Interdisciplinary Vision of the Digitalized Future Energy Systems
Creators: Zhao Yang Dong and Yuchen Zhang
Publisher: name: IEEE

This paper envisages interdisciplinary digitalized future energy systems for emission reductions and proposes a 6-theme template to shape the future energy system.
Global energy systems are transforming from fossil fuels to renewables, but the conventional electricity systems are so fragile that could lead to negative consequences such as soaring prices, rolling blackouts, security issues and delays to emission reductions. Confronting to these issues, electricity systems of the future will be vastly changed, dominated by new technologies and business models, increasingly digital and highly complex. Such transformation will be enabled by means to efficiently, stably and affordably distribute electrical power from many sources and storage points. Market design, policy, regulations, legislations, cyber security and politics are barely keeping up with advances in technologies, and energy technology choices have multi-generational implications for people and economies. These issues are global and to find a solution requires true systems thinking, informed by cutting-edge research. This paper envisages interdisciplinary digitalized future energy systems for emission reductions and proposes a 6-theme template to shape the future energy system. The six research themes have been designed such that the "whole is greater than the sum of the parts''. Each theme is informed by the others and the inter-linking of the six themes' inputs and outputs will drive the outcomes and impacts of future energy systems.

This paper provides an overview of several applications of synchrophasor data utilizing the low-rank property.
There is a growing acceptance of using synchrophasor data collected over large power systems in control centers to enhance the reliability of power system operations. The spatial and temporal nature of power system ambient and disturbance response allows the analysis of large amount of synchrophasor data by low-rank methods. This paper provides an overview of several applications of synchrophasor data utilizing the low-rank property. The tools to capitalize on the low-rank property include matrix completion methods, tensor analysis, adaptive filtering, and machine learning. The applications include missing data recovery, bad data correction, and disturbance recognition.

description: Nearby young clusters are privileged places to study the star formation history. Over the last decade, the sigma-Orionis cluster has been a prime location for the study of young very low mass stars, substellar and isolated planetary mass objects and the determination of the initial mass function. To extend previous studies of this association to its core, we searched for ultracool members and new multiple systems within the 1.5'x1.5' central region of the cluster. We obtained deep multi-conjugate adaptive optics (MCAO) images of the core of the sigma-Orionis cluster with the prototype MCAO facility MAD at the VLT using the H and Ks filters. These images allow us to reach Delta H~5mag as close as 0.2" on a typical source with H=14.5mag. These images were complemented by archival SofI Ks-band images and Spitzer IRAC and MIPS mid-infrared images. We report the detection of 2 new visual multiple systems, one being a candidate binary proplyd and the other one a low mass companion to the massive star sigma Ori E. Of the 36 sources detected in the images, 25 have a H-band luminosity lower than the expected planetary mass limit for members, and H-Ks color consistent with the latest theoretical isochrones. Nine objects have additional Spitzer photometry and spectral energy distribution consistent with them being cluster members. One of them has a spectral energy distribution from H to 3.6micron consistent with that of a 5.5 MJup cluster member. Complementary NTT/SofI and Spitzer photometry allow us to confirm the nature and membership of two L-dwarf planetary mass candidates.

description: We present a variational approach based on the string picture to analyze the internal structure and dispersion of spin polarons with different symmetries in an antiferromagnet. We then use this to discuss the properties of underdoped cuprate superconductor within the `doped insulator' picture. The theory explains the remnant Fermi surface for the undoped compunds, as well as hole pockets, Fermi arcs, high energy pseudogap and the the mid-infrared band in doped materials. Destructive interference between the phases of a photohole near $Γ$ and the internal phases of the Zhang Rice singlet combined with our theory moreover explains the `waterfall' phenomenon.

Because of rotational symmetry of the spheroid the solutions are separated by the azimuthal index $m$. By the two-fold variation of a refractive index and the aspect ratio we achieve exceptional points (EPs) at which the resonant frequencies and resonant modes are coalesced in the sectors $m=0$ for both TE and TM polarizations and $m=1$.

description: We treat the spin injection and extraction via a ferromagnetic metal/semiconductor Schottky barrier as a quantum scattering problem. This enables the theory to explain a number of phenomena involving spin-dependent current through the Schottky barrier, especially the counter-intuitive spin polarization direction in the semiconductor due to current extraction seen in recent experiments. A possible explanation of this phenomenon involves taking into account the spin-dependent inelastic scattering via the bound states in the interface region. The quantum-mechanical treatment of spin transport through the interface is coupled with the semiclassical description of transport in the adjoining media, in which we take into account the in-plane spin diffusion along the interface in the planar geometry used in experiments. The theory forms the basis of the calculation of spin-dependent current flow in multi-terminal systems, consisting of a semiconductor channel with many ferromagnetic contacts attached, in which the spin accumulation created by spin injection/extraction can be efficiently sensed by electrical means. A three-terminal system can be used as a magnetic memory cell with the bit of information encoded in the magnetization of one of the contacts. Using five terminals we construct a reprogrammable logic gate, in which the logic inputs and the functionality are encoded in magnetizations of the four terminals, while the current out of the fifth one gives a result of the operation.

Ezra Pound’s early experiments with major forms, 1904-1925 : Directio Voluntatis
Creators: name: McKeown, Thomas Wilson
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation argues that the coherent vision and single impulse which led to the major form of the Cantos also underlay Ezra Pound's seemingly disparite early experiments. In order to demonstrate that Pound's pre-occupation with major form provided a common denominator between his earliest, middle, and mature poetry, I have divided this study into three sections, which correspond to the three main stages of Pound's development. Part One: Instigation (1904-1911), demonstrates the two theories of perfect form that first attracted the young Pound, and documents his drive toward ever-subtler architectonic structures in his initial phase of development. Part Two: Experiment (1912-1919), re-defines the three qualities of rhythm, tone, texture, as they apply to Pound's experiments with major form. Part Three: Accomplishment (1920-1925), describes what stimulated Pound's theoretical breakthrough in 1922, and traces the expression of this theory through XVI Cantos, to show that this first installment of Pound's major poem fused his theory and practice of poetry. This achievement can only be properly appreciated properly, however, in the context of his earlier twenty-year experiment with other major forms. The Conclusion points out that the critical moment in the evolution of Pound's exploration of major forms occurred when he dropped his aspiration to write a purely personal document featuring "perfect" form, and became content to write a broader social "testament." Underneath the formal superstructures of his attempts at major form, Pound's holistic vision provided the base, or "unwobbling pivot", for his attempt to "show men the way to try" to gain a more comprehensive understanding of the patterned integrities of the "vital universe": stone, tree, and mind—alive.

This paper investigates real-time self-dispatch of a remote wind-storage integrated power plant connecting to the main grid via a transmission line with a limited capacity.
This paper investigates real-time self-dispatch of a remote wind-storage integrated power plant connecting to the main grid via a transmission line with a limited capacity. Because prediction is a complicated task and inevitably incurs errors, it is a better choice to make real-time decisions based on the information observed in the current time slot without predictions on the uncertain electricity price and wind generation in the future. To this end, the operation problem is formulated under the Lyapunov optimization framework to maximize the long-term time-average revenue of the wind-storage plant. Inter-temporal storage dynamics are represented by a virtual queue which is mean rate stable. An online method for real-time dispatch is proposed based on Lyapunov drift algorithm via a drift-minus-revenue function. The upper bound of such a function, which does not depend on future uncertainty, is minimized in each time slot. Explicit dispatch policies are obtained through multi-parametric programming technique so that no optimization problem is solved online. It is proved that the online algorithm can maintain all the constraints across the entire horizon and the expected optimality gap compared to the deterministic offline optimum with perfect uncertainty information is inversely proportional to the weight coefficient in the drift-minus-revenue function. Numerical tests using real wind and electricity price data validate the effectiveness and performance of the proposed method.
Coupled two-component atomic gas in an optical lattice

description: We present an ab initio study of the ground state of an ideal coupled two-component gas of ultracold atoms in a one dimensional optical lattice, either bosons or fermions. Due to the internal two-level structure of the atoms, the Brillouin zone is twice as large as imposed by the periodicity of the lattice potential. This is reflected in the Bloch dispersion curves, where the energy bands regularly possess several local minima. As a consequence, when the system parameters are tuned across a resonance condition, a non-zero temperature phase transition occurs which arises from an interplay between internal and kinetic atomic energies. For fermions, this phase transition is of topological character since the structure of the Fermi surface is changed across the critical value. It is shown that these phenomena are also expected to occur for two and three dimensional optical lattices.

description: Detecting abnormal activities in real-world surveillance videos is an important yet challenging task as the prior knowledge about video anomalies is usually limited or unavailable. Despite that many approaches have been developed to resolve this problem, few of them can capture the normal spatio-temporal patterns effectively and efficiently. Moreover, existing works seldom explicitly consider the local consistency at frame level and global coherence of temporal dynamics in video sequences. To this end, we propose Convolutional Transformer based Dual Discriminator Generative Adversarial Networks (CT-D2GAN) to perform unsupervised video anomaly detection. Specifically, we first present a convolutional transformer to perform future frame prediction. It contains three key components, i.e., a convolutional encoder to capture the spatial information of the input video clips, a temporal self-attention module to encode the temporal dynamics, and a convolutional decoder to integrate spatio-temporal features and predict the future frame. Next, a dual discriminator based adversarial training procedure, which jointly considers an image discriminator that can maintain the local consistency at frame-level and a video discriminator that can enforce the global coherence of temporal dynamics, is employed to enhance the future frame prediction. Finally, the prediction error is used to identify abnormal video frames. Thoroughly empirical studies on three public video anomaly detection datasets, i.e., UCSD Ped2, CUHK Avenue, and Shanghai Tech Campus, demonstrate the effectiveness of the proposed adversarial spatio-temporal modeling framework.

description: We present a new approach, kernel regression, to determine photometric redshifts for 399,929 galaxies in the Fifth Data Release of the Sloan Digital Sky Survey (SDSS). In our case, kernel regression is a weighted average of spectral redshifts of the neighbors for a query point, where higher weights are associated with points that are closer to the query point. One important design decision when using kernel regression is the choice of the bandwidth. We apply 10-fold cross-validation to choose the optimal bandwidth, which is obtained as the cross-validation error approaches the minimum. The experiments show that the optimal bandwidth is different for diverse input patterns, the least rms error of photometric redshift estimation arrives at 0.019 using color+eClass as the inputs, the less rms error amounts to 0.020 using ugriz+eClass as the inputs. Here eClass is a galaxy spectra type. Then the little rms scatter is 0.021 with color+r as the inputs.

This paper proposes a probabilistic transient stability-constrained preventive dispatching method for power systems under a high inclusion of wind power.
This paper proposes a probabilistic transient stability-constrained preventive dispatching method for power systems under a high inclusion of wind power. First, a set of instability mode (IM)-categorized probabilistic transient stability constraints (PTSCs) are constructed, which facilitate the development of a dispatching plan against various fault scenarios. Next, to avoid massive transient stability simulations in each dispatching operation, a machine learning-based model is trained to predict the critical clearing time (CCT) and IM for all preconceived fault scenarios. Based on the predictions, the system operation plan is assessed with respect to the PTSCs. Then, the sensitivity of the probabilistic level of the CCT is calculated to the active power generated from the critical generators for each IM category. Accordingly, the implicit PTSCs are converted into explicit dispatching constraints, and the dispatch is rescheduled to ensure the probabilistic stability requirements of the system are met at an economical operating cost. The proposed approach is validated on two modified IEEE test systems, reporting high computational efficiency and high-quality solutions.

description: Magnetohydrodynamic (MHD) waves are candidates for heating the solar chromosphere, although it is still unclear which mode of the wave is dominant in heating. We perform two-dimensional radiative MHD simulation to investigate the propagation of MHD waves in the quiet region of the solar chromosphere. We identify the mode of the shock waves by using the relationship between gas pressure and magnetic pressure across the shock front and calculate their corresponding heating rate through the entropy jump to obtain a quantitative understanding of the wave heating process in the chromosphere. Our result shows that the fast magnetic wave is significant in heating the low-beta chromosphere. The low-beta fast magnetic waves are generated from high-beta fast acoustic waves via mode conversion crossing the equipartition layer. Efficient mode conversion is achieved by large attacking angles between the propagation direction of the shock waves and the chromospheric magnetic field.

description: This paper presents a more complete version than hitherto published of our explanation of a transition from regular to irregular motions and more generally of the nature of a certain kind of deterministic chaos. To this end we introduced a simple model analogous to a three-body problem in the plane, whose general solution is obtained via quadratures all performed in terms of elementary functions. For some values of the coupling constants the system is isochronous and explicit formulas for the period of the solutions can be given. For other values, the motions are confined but feature aperiodic (in some sense chaotic) motions. This rich phenomenology can be understood in remarkable, quantitative detail in terms of travel on a certain (circular) path on the Riemann surfaces defined by the solutions of a related model considered as functions of a complex time. This model is meant to provide a paradigmatic first step towards a somewhat novel understanding of a certain kind of chaotic phenomena.

description: Most research data collections created or used by astronomers are intrinsically multi-dimensional. In contrast, all visual representations of data presented within research papers are exclusively 2-dimensional. We present a resolution of this dichotomy that uses a novel technique for embedding 3-dimensional (3-d) visualisations of astronomy data sets in electronic-format research papers. Our technique uses the latest Adobe Portable Document Format extensions together with a new version of the S2PLOT programming library. The 3-d models can be easily rotated and explored by the reader and, in some cases, modified. We demonstrate example applications of this technique including: 3-d figures exhibiting subtle structure in redshift catalogues, colour-magnitude diagrams and halo merger trees; 3-d isosurface and volume renderings of cosmological simulations; and 3-d models of instructional diagrams and instrument designs.

This paper deals with the derivation of dynamic equivalents of active distribution networks, hosting inverter-based generators as well as static and motor loads.
This paper deals with the derivation of dynamic equivalents of active distribution networks, hosting inverter-based generators as well as static and motor loads. Equivalents are reduced-order models for use in dynamic simulations of the transmission system. They are of the grey-box types and their parameters are identified from large-disturbance Monte-Carlo simulations accounting for model uncertainty. After presenting an overview of the identification method at a single operating point, the paper deals with the update the equivalent when the operating conditions of the distribution network change. A procedure identifies the parameters to update, hence avoiding a complete new identification. Besides illustrative examples, two sets of simulation results are reported. First, the accuracy of the equivalent is validated in a long-term voltage instability scenario. Second, a larger-scale application is presented, with numerous instances of the equivalent attached to the model of the IEEE Nordic transmission test system. This combined model is used to assess the impact on short- and long-term voltage stability of the inverter-based generators with fast and slow controls.

description: Population studies of stellar-mass black-hole binaries have become major players in gravitational-wave astronomy. The underlying assumptions are that the targeted source parameters refer to the same quantities for all events in the catalog and are included when modeling selection effects. Both these points have so far been neglected when estimating the orientations of the black-hole spins. In particular, the detector-frame gravitational-wave frequency used to define frequency-dependent quantities (e.g., 20 Hz) introduces an inconsistent reference between events at the population level. We solve both issues by modeling binary black-hole populations and selection effects at past time infinity, corresponding to the well-defined reference frequency of 0 Hz. We show that, while current gravitational-wave measurement uncertainties obfuscate the influence of reference frequency in population inference, ignoring spins when estimating selection effects leads to an over-prediction of spin alignment in the underlying astrophysical distribution of merging black holes.

description: Let $X$ be an irreducible smooth projective curve of genus $g\ge3$ defined over the complex numbers and let ${\mathcal M}_ξ$ denote the moduli space of stable vector bundles on $X$ of rank $n$ and determinant $ξ$, where $ξ$ is a fixed line bundle of degree $d$. If $n$ and $d$ have a common divisor, there is no universal vector bundle on $X\times {\mathcal M}_ξ$. We prove that there is a projective bundle on $X\times {\mathcal M}_ξ$ with the property that its restriction to $X\times\{E\}$ is isomorphic to $P(E)$ for all $E\in\mathcal{M}_ξ$ and that this bundle (called the projective Poincaré bundle) is stable with respect to any polarization; moreover its restriction to $\{x\}\times\mathcal{M}_ξ$ is also stable for any $x\in X$. We prove also stability results for bundles induced from the projective Poincaré bundle by homomorphisms $\text{PGL}(n)\to H$ for any reductive $H$. We show further that there is a projective Picard bundle on a certain open subset $\mathcal{M}'$ of $\mathcal{M}_ξ$ for any $d>n(g-1)$ and that this bundle is also stable. We obtain new results on the stability of the Picard bundle even when $n$ and $d$ are coprime.

Active and reactive power control using smart inverters (SI) is highly effective in mitigating voltage rise in distribution systems, which is caused by the high penetration of photovoltaic (PV) power generation. However, the voltage control performance depends on the SI settings. We propose a new approach that uniquely determines the parameter settings for volt-VAR-watt control based on the active and reactive power-voltage sensitivity matrix of SIs. Because the voltage sensitivity matrix is calculated based solely on the impedance of the distribution system and it does not vary with time or the number of SIs, the proposed method can determine the individual SI parameter settings theoretically and efficiently without the need for optimization problem formulation, power flow calculation, or communication between the SIs. To evaluate the proposed method, the voltage control performance in a real distribution system model with a large number of PV installations is compared with that of volt-VAR-watt control using default parameters and optimized parameters in case that the load demand and PV generation are given in advance. The results show that the proposed method achieves better control performance than other conventional methods in terms of all the evaluation indices; in particular, it realizes effective control in the case of voltage rise. Furthermore, the proposed method can also achieve the same level of voltage control performance as the optimization results, even though it uses only the voltage sensitivity matrix and SI rating capacities for parameters determination, and the accuracy of the proposed voltage control can be ensured.

description: The discovery of fast radio burst (FRB) 200428 from galactic SGR J1935+2154 makes it possible to measure rotational changes accompanied by FRBs and to test several FRB models which may be simultaneously associated with glitches. Inspired by this idea, we present order of magnitude calculations to the scenarios proposed. FRB models such as global starquakes, crust fractures and collisions between pulsars and asteroids/comets are discussed. For each mechanism, the maximum glitch sizes are constrained by the isotropic energy release during the X-ray burst and/or the SGR J1935+2154-like radio burst rate. Brief calculations show that, the maximum glitch sizes for different mechanisms differ by order(s) of magnitude. If glitches are detected to be coincident with FRBs from galactic magnetars in the future, glitch behaviors (such as glitch size, rise timescale, the recovery coefficient and spin down rate offset) are promising to serve as criterions to distinguish glitch mechanisms and in turn to constrain FRB models.

Platform Intermediaries in the Sharing Economy: Questions of Liability and Remedy

description: National and international characteristics of sharing economy imply that a platform intermediary may hold a dominant legal and economic position between a debtor and a creditor. Legally, such an agent will be the commercial link between the performance debtor and the performance creditor. Hence, the platform intermediary’s contractual obligations do not appertain to the performance creditor by default but to the economic and legal nexus between the committed and legitimate contractors. Yet recent legal practice in Danish substantive law, along with a series of court rulings, indicates that a platform intermediary may under certain circumstances be considered duty subject in relation to the performance creditor. In such cases, the platform intermediary—though originally deemed an agent—is contractually obliged to the performance debtor. This creates two interesting legal issues which are analysed in our article. First, we address the requirements and circumstances which may lead to the platform intermediary being directly liable to the performance creditor in case of non-performance of the sharing economy service in question. Secondly, we analyse which remedies the performance creditor can impose on the intermediary in a situation where the intermediary is considered contractually obliged to the performance debtor.

description: The relative effective population sizes of populations of ascomycete fungi can be estimated based on skews in the frequency of mating type idiomorphs and based on the frequency of hermaphrodites in the population. Additionally, the frequency of hermaphrodites can be used to estimate the relative frequency of sexual reproduction in populations with a mixed mode of reproduction, where individuals reproduce by vegetative propagation and occasional sexual reproduction. To aid in the computation of relative effective population sizes (Ne), the expected range of hermaphrodite frequencies in a stable equilibrium of fluctuating hermaphrodite frequencies, and the number of asexual generations per sexual generation, g, I have created spreadsheet templates with the relevant equations encoded. The first template presents formulas to compute the two relative Ne estimates. The second template takes the observed frequency of hermaphrodites from a population and computes the expected minimum and maximum frequencies of hermaphrodites in the equilibrium cycle of asexual generations between each nonconsecutive sexual generation, the expected number of asexual generations in each cycle under various assumptions, and this last quantity’s inverse, which can be interpreted as the proportion of individuals participating in sexual reproduction in any given generation. The template also calculates the mean number of mutations to female sterility per strain both before and after sexual reproduction under the dual assumptions that the sample has just completed a sexual generation and that it was just about to start one.

This paper reviews the challenges associated with renewable energy resource integration on system frequency response and how these challenges affect system reliability.
Due to their many advantages, renewable energy resources (RERs) are proliferating rapidly to satisfy a significant portion of the global energy demand. It is predicted that the importance of RER generation will continue to increase in the future of the energy industry. In spite of all their known benefits, the integration of RERs poses several challenges to system stability and reliability. Low inertia characteristics and the intermittent output of RERs introduces additional variation into an already variable grid frequency. System regulation capability and reliability are reduced as RERs gradually replace conventional generators. This paper reviews the challenges associated with RER integration on system frequency response and how these challenges affect system reliability. Advanced methods for mitigating challenges associated with increasing RER integration, while ensuring system security, are discussed, and the necessary mathematical background is provided in concise form. A model is developed for determining the maximum level of RER penetration based on stability constraints. Emerging methods to advance the integration of RERs are discussed.

description: Η εργασία αυτή εξετάζει πώς οι αναμνήσεις επηρεάζουν την αντίληψη του χώρου και την αρχιτεκτονική. Ξεκινώντας από βασικές αρχές της μνήμης και της αντίληψης, αναλύεται η διαφορά ανάμεσα στην προσωπική και τη συλλογική μνήμη, καθώς και ο ρόλος των αισθήσεων στη δημιουργία και ανάκληση μνημών. Στη συνέχεια, παρουσιάζονται τα αρχιτεκτονικά αρχέτυπα και η σύνδεσή τους με τη μνήμη μέσα από ιστορικά και πολιτισμικά παραδείγματα. Η εργασία αναλύει επίσης τον τρόπο με τον οποίο καλλιτέχνες, σκηνογράφοι και αρχιτέκτονες ενσωματώνουν τη συλλογική μνήμη στο έργο τους, όπως το Εβραϊκό Μουσείο Βερολίνου. Στην ενότητα της προσωπικής μνήμης, διερευνάται πώς η ανάμνηση διαμορφώνει την αντίληψη του οικείου χώρου, με παραδείγματα έργων όπου οι αρχιτέκτονες σχεδίασαν τις δικές τους κατοικίες, καθώς και με μια πιο προσωπική αναφορά στο σπίτι της γιαγιάς μου. Τέλος, τα συμπεράσματα αναδεικνύουν τη βαθιά σχέση μεταξύ μνήμης και χώρου, υπογραμμίζοντας πώς οι αναμνήσεις μας καθορίζουν την ταυτότητα των χώρων που μας περιβάλλουν.
description: This study explores how memories influence spatial perception and architecture. Beginning with fundamental principles of memory and perception, it examines the distinction between personal and collective memory, as well as the role of the senses in creating and recalling memories. Subsequently, architectural archetypes and their connection to memory are presented through historical and cultural examples.The study also analyzes how artists, scenographers, and architects incorporate collective memory into their work, with examples such as the Jewish Museum Berlin. In the section on personal memory, it investigates how reminiscence shapes the perception of familiar spaces, including case studies of architects designing their own homes.

description: The descent algebra of the symmetric group, over a field of non-zero characteristic p, is studied. A homomorphism into the algebra of generalised p-modular characters of the symmetric group is defined. This is then used to determine the radical, and its nilpotency index. It also allows the irreducible representations of the descent algebra to be described.

description: We study the effects of the introduction of a $\vartheta$ term in minimal gauged supergravity in four dimensions. We show why this term is not present in supergravity duals of field theories arising on wrapped $M2$-branes, but is there in the case of $M5$-branes wrapping hyperbolic manifolds $Σ_3$, and compute the higher-derivative corrections. Having proved that the on-shell supergravity action of any supersymmetric solution can be expressed in terms of data from the fixed points of a Killing vector, we show that it is proportional to a complex topological invariant of $Σ_3$. This is consistent with the characteristics of the dual three-dimensional $\mathcal{N}=2$ SCFT predicted by the $3d$-$3d$ correspondence, and we match the large $N$ limit of its partition functions in the known cases.

This paper explores various technologies available for power generation, storage, and distribution for space microgrids on the Moon.
Several space organizations have been planning to establish a permanent, manned base on the Moon in recent years. Such an installation demands a highly reliable electrical power system (EPS) to supply life support systems and scientific equipment and operate autonomously in a fully self-sufficient manner. This paper explores various technologies available for power generation, storage, and distribution for space microgrids on the Moon. Several factors affecting the cost and mass of the space missions are introduced and analysed to provide a comprehensive comparison among the available solutions. Besides, given the effect of base location on the design of a lunar electrical power system and the mission cost, various lunar sites are introduced and discussed. Finally, the control system requirements for the reliable and autonomous operation of space microgrids on the Moon are presented. The study is complemented by discussing promising future technological solutions that could be applied upon a lunar microgrid.
