PV in the Electricity Markets

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 3894-3900
description: This study builds on a 2013 paper from M.Gourvitch, M.Gouzerh, M.Carton and M.Masson on “Quantitative analysis of the merit order effect from photovoltaic production in Italy”. This study proposes a method to quantify the savings incurred by the end consumers in a set of European countries over the past 8 years as a result of the decrease in electricity spot market prices observed when PV plants feed electricity into the grid. The 2013 study showed that the total electricity demand retreated by PV production is well correlated to market prices, following a stable exponential curve. Estimating such curve enables to calculate what the additional energy payments would have been had there been no PV production. Such gain, called merit order effect, has varied over time. This study will research whether the same effect can be seen in other European countries, France, Germany, Austria and Switzerland. The authors have run Monte Carlo simulations on a large number of irradiation profiles and showed that the merit order effect does not depend much on the PV penetration rate but rather on the electricity demand profile, and therefore on how well it correlates with the PV production profile. The social gain expressed per MWh of PV electricity fed into the grid gets close to 100 €/MWh, and has exceeded € 20 Bn at the country scale over the past 7 years. Also, average wholesale prices would have been 3% (or 1.5 €/MWh) higher had there been no PV production. If that money could be captured by the government, it could be used to finance support schemes and grid infrastructure works for instance.

description: We study the gravitational collapse of a homogeneous time-dependent scalar field that, besides its coupling to curvature, it is also kinematically coupled to the Einstein tensor. This coupling is a part of the Horndeski theory and we investigate its effect on the collapsing process. We find that the time required for the scalar field to collapse depends on the value of the derivative coupling and the singularity is protected by a horizon. Matching the internal solution with an external Schwarzschild- AdS metric we show that a black hole is formed, while the weak energy condition is satisfied during the collapsing process. The scalar field takes on a finite value at the singularity.

description: Solar cells used in building integrated photovoltaic (BIPV) cells are traditionally made from crystalline
wafer cells. This contribution addresses the assessment of thin-film silicon solar cells and their potential use in BIPV
cell application, especially in the case of bifacial solar cells. We tested single junction and multi junction layouts and
evaluated their benefits and challenges in their use as bifacial BIPV cells. We optimized our single junction bifacial
cell in terms of back contact and n-layer and managed to double its output power when illuminated from both sides.
Our multi junction bifacial solar cell experiments achieved 122 % output power with twice the Voc compared to the
single junction cells by improving the tunnel recombination junction.

description: The installed capacity of photovoltaic (PV) is rising steadily. Most PV is installed in highly electrified countries as on-grid systems. Further, there are reams of small off-grid systems in rural areas of developing countries. Due to this, reliable installation rates for PV are available only for a small number of countries. For the end of 2013 EPIA reports 138,858 MWp of installed PV capacity, using data for 45 countries, whereas 2,098 MWp are not allocatable to specific countries. IEA-PVPS gives a number of 136,200 MWp installed by providing detailed data for 32 countries, 24 of which coming from official sources in IEA PVPS member countries. This paper gives an overview of installed PV for all countries in the world, being predicated based on the examination of publically accessible data. Furthermore, an analysis of the development of cumulative PV capacities in recent years is given. Resulting from this evaluation, PV installations are localized in 191 countries, representing 137,500 MWp.

description: We characterize the 795 nm $^3$H$_6$ to $^3$H$_4$ transition of Tm$^{3+}$ in a Ti$^{4+}$:LiNbO$_{3}$ waveguide at temperatures as low as 800 mK. Coherence and hyperfine population lifetimes -- up to 117 $μ$s and 2.5 hours, respectively -- exceed those at 3 K at least ten-fold, and are equivalent to those observed in a bulk Tm$^{3+}$:LiNbO$_{3}$ crystal under similar conditions. We also find a transition dipole moment that is equivalent to that of the bulk. Finally, we prepare a 0.5 GHz-bandwidth atomic frequency comb of finesse $>$2 on a vanishing background. These results demonstrate the suitability of rare-earth-doped waveguides created using industry-standard Ti-indiffusion in LiNbO$_3$ for on-chip quantum applications.

Die Patienten erhielten 20mg/Kg Triclabendazol in 2 Dosierungen a 10 mg/Kg im Abstand von 12 h postprandial. Der Therapieerfolg wurde durch mikroskopische Stuhluntersuchungen, Bestimmung exkretorisch-sekretorischer Antigene im Stuhl und Ultraschall überprüft. Bei Siebzig (92%) von 76 Patienten konnten in der Nachuntersuchungsperiode (60 Tage) keine Fasciola hepatica-Eier in den mikroskopischen Stuhluntersuchungen nachgewiesen werden. Die häufigsten unerwünschten Wirkungen waren kolikartige Oberbauchbeschwerden, die bei 40 Patienten (49%) zeitgleich mit der Passage der Parasiten durch die Gallengänge beobachtet wurden. Triclabendazol ist eine effektive Therapie für Patienten mit Fasziolose bei denen andere antihelmithische Therapien nicht wirksam sind.
description: The efficacy and tolerability of triclabendazole (TCZ) was assessed in a clinical phase 2 study. Eighty-one patients (51 female, 30 male, age 15- 81 years) with chronic or latent F. hepatica infection refractory to previous anti-helminthic chemotherapy were enrolled in a 60 day open, non-comparative trial. Patients received 20 mg/kg TCZ as two doses of 10 mg/kg administered after food 12 hr apart. Efficacy of treatment was assessed by stool microscopy, determination of fasciola excretory-secretory antigen in feces, and by ultrasonography. Seventy (92%) of the 76 patients who completed the 60 day follow up period became egg negative. The most important adverse event was colic-like abdominal pain (40 patients [49%]) consistent with the expulsion of the parasite through the bile ducts as confirmed by US on Days 2 - 7. Triclabendazole is an effective therapy for the treatment of F. hepatica infection in patients who have failed to respond to other antihelminthic agents.

description: Introduction

Thermal Pollution is the harmful increase in water temperature in streams, rivers, lakes, or occasionally, coastal ocean waters.It is the degradation of water quality by any process that changes ambient water temperature.A temperature increase as small as 1 or 2 Celsius degrees (about 2 to 4 Fahrenheit degrees) can kill native fish, shellfish, and plants, or drive them out in favor of other species, often with undesirable effects.

When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects ecosystem composition.Fish and other organisms adapted to particular temperature range can be killed by an abrupt change in water temperature (either a rapid increase or decrease) known as “Thermal shock.”

PV as Building Material Component (focus on technical issues)

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 3733-3737
description: The paper presents the refurbishment of a residential building located in Chiasso (Switzerland) fully
covered by photovoltaic modules.
The eight storey apartment house was built in 1965 and after 45 years it was decided, due to its bad condition, to
refurbish it. The building owner has set itself the target to totally renovate the building and to achieve the passive
house standard. At the beginning of the construction phase, the builders put the goals even higher, deciding that by
the use of BIPV modules to the entire facades they can achieve the Plus energy house standard (netZero Energy
building). The renovation ended in November 2013. Beside the BIPV facades, a single-axis tracking photovoltaic
plant was also installed on the pergola roof terrace in October of 2013 as a last resort.
This paper describes the building before and after renovation and discusses the critical points in the planning phase
and during construction. Moreover, in order to assess the mechanical stability of the glass-glass a-Si module
assembly on the facade, mechanical stress tests were performed in the SUPSI laboratories, which are explained in
detail in this paper together with an accurate raytracing analysis (based on RADIANCE tool simulation) done to
optimize the BIPV module strings and consequently to increase the energy production on an annual basis.

description: Control of dopants in silicon remains the most important approach to tailoring the properties of electronic materials for integrated circuits, with Group V impurities the most important n-type dopants. At the same time, silicon is finding new applications in coherent quantum devices, thanks to the magnetically quiet environment it provides for the impurity orbitals. The ionization energies and the shape of the dopant orbitals depend on the surfaces and interfaces with which they interact. The location of the dopant and local environment effects will therefore determine the functionality of both future quantum information processors and next-generation semiconductor devices. Here we match observed dopant wavefunctions from low-temperature scanning tunnelling microscopy (STM) to images simulated from first-principles density functional theory (DFT) calculations. By this combination of experiment and theory we precisely determine the substitutional sites of neutral As dopants between 5 and 15A below the Si(001):H surface. In the process we gain a full understanding of the interaction of the donor-electron state with the surface, and hence of the transition between the bulk dopant (with its delocalised hydrogenic orbital) and the previously studied dopants in the surface layer.

description: In dieser Arbeit werden Berechnungen zur klimatischen Sensitivität der Eiskappe von Devon Island (Nunavut, Kanada) durchgeführt, die auf einem mit Wärmesummen arbeitenden Massenbilanzmodell basieren. Wichtigste Datenbasis für die Modellrechnungen sind dabei höhenabhängige Massenbilanzreihen der Devon-Eiskappe sowie tägliche Klimadaten der WMO-Station Resolute Bay. Durch die Bestimmung geeigneter Modellparameter (Temperaturgradienten, Wärmesummenkoeffizienten) ist es möglich, das mittlere Massenbilanzprofil gut zu simulieren. Das auf diese Weise kalibrierte Modell kann dann – als einfache Alternative zu Energiebilanzmodellen – zur Berechnung der Sensitivität der Massenbilanz auf Veränderungen von Temperatur und Niederschlag genutzt werden. Anwendungen des Modells verdeutlichen, dass die Massenbilanz der Devon-Eiskappe stark abhängig von der Entwicklung der Sommertemperaturen und die klimatische Sensitivität im Vergleich mit anderen Eismassen aus feuchteren Klimaten sehr klein ist. Die Einbeziehung der saisonalen Abhängigkeit der Massenbilanz kann schließlich helfen, eine mit Schwierigkeiten verbundene Rekonstruktion der jährlichen Massenbilanz zu verbessern.
description: In this study, a degree-day approach is used to carry out model simulations to determine the climatic sensitivity of the mass balance of the Devon Island ice cap (Nunavut, Canada). The most important data the model is fed by are a 38 yr long series of specific mass balance data and daily air temperature data from the WMO station Resolute Bay. By determining suitable model parameters (temperature lapse rates, degree-day coefficients) it is possible to simulate the mean mass balance profile convincingly. As a simple alternative to energy balance models, the calibrated degree-day model can then be used to determine the sensitivity of the mass balance to changes in temperature and precipitation. Results show that the mass balance of the Devon Ice Cap is strongly dependent on the summer temperatures and that the overall climatic sensitivity is small compared to those of other ice masses in more humid regions. The reconstruction of the mass balance series is attended with difficulties, but can be improved by including the mass balance''s seasonal sensitivity.
Nonparametric imputation method for nonresponse in surveys

description: Many imputation methods are based on statistical models that assume that the variable of interest is a noisy observation of a function of the auxiliary variables or covariates. Misspecification of this model may lead to severe errors in estimates and to misleading conclusions. A new imputation method for item nonresponse in surveys is proposed based on a nonparametric estimation of the functional dependence between the variable of interest and the auxiliary variables. We consider the use of smoothing spline estimation within an additive model framework to flexibly build an imputation model in the case of multiple auxiliary variables. The performance of our method is assessed via numerical experiments involving simulated and real data.

description: The present work includes aspects for the optimized use of photovoltaics, combined effectively with
other RES and environmental technologies in the buildings, to achieve energy saving, minimizing building pollutants,
especially in existing buildings and resulting to cost effective building eco retrofitting. Solar energy systems appear
as a new material in the architect’s hands, ready to be shaped to create alternative buildings and they can be an
important part of the building design. Towards zero energy buildings, a more frequent installation of photovoltaics to
buildings will be performed, effectively combined with other smart building energy technologies. In this paper the
parameters to optimize the contribution of photovoltaics to building energy demand and the technologies for building
eco retrofitting are presented. For the case of photovoltaics, their mounting on building facades and inclined roofs
causes electrical output reduction due to view and to heat problems, from their installation. We studied the effect of
azimuth and slope angles of PV panels to the corresponding electricity output, their temperature increase from
mounting thermal loss suppression and the energy output rise by using diffuse reflectors. The design of a new and
low cost PV/T collector is presented, including results from outdoors laboratory experiments. Finally, considerations
for energy and building eco improvement suggestions to a Greek building are presented and analyzed.

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 3658-3661
description: The aim of this paper is to demonstrate the technical potential of the combination of Building
Integrated Photovoltaics (BIPV) and supercapacitor storage in a smart apartment complex. The BIPV set-up
described in this paper can connect up to 16 60-cell PV modules. Each module is equipped with an individual dc-dc
converter which connects the module to the supercapacitor storage. Each module is thus equipped with an individual
MPP tracker to increase the yield of the installation when some modules are (partially) shaded. The supercapacitor
pack is a 268 F module operated between 78 and 120 V. The purpose of the supercapacitor storage is two-fold; Firstly
the power fluctuations originating from the BIPV are mitigated by the supercapacitor storage and secondly the peak
consumers of the smart apartment complex are powered by the PV-supercapacitor system if sufficient power and
energy storage is available. The first functionality is demonstrated in a first case wherein the grid power slowly varies
over a period of several minutes despite an abrupt change in the PV output. The second functionality is demonstrated
in a second case wherein the supercapacitor supplies the energy demand of several communal loads without drawing
any grid current.

description: Turaev conjectured that the classification, realization and splitting results for Poincaré duality complexes of dimension $3$ (PD$_{3}$-complexes) generalize to PD$_{n}$-complexes with $(n-2)$-connected universal cover for $n \ge 3$. Baues and Bleile showed that such complexes are classified, up to oriented homotopy equivalence, by the triple consisting of their fundamental group, orientation class and the image of their fundamental class in the homology of the fundamental group, verifying Turaev's conjecture on classification. We prove Turaev's conjectures on realization and splitting. We show that a triple $(G, ω, μ)$, comprising a group, $G$, a cohomology class $ω\in H^{1}\left(G, \mathbb{Z}/2\mathbb{Z}\right)$ and a homology class $μ\in H_{n}(G, \mathbb{Z}^ω)$, can be realized by a PD$_{n}$-complex with $(n-2)$-connected universal cover if and only if the Turaev map applied to $μ$ yields is an equivalence. We show that such a PD$_{n}$-complex is a connected sum of two such complexes if and only if its fundamental group is a free product of groups. We then consider the indecomposable $PD_n$-complexes of this type. When $n$ is odd the results are similar to those for the case $n=3$. The indecomposables are either aspherical or have virtually free fundamental group. When $n$ is even the indecomposables include manifolds which are neither aspherical nor have virtually free fundamental group, but if the group is virtually free and has no dihedral subgroup of order $>2$ then it has two ends.

description: Quantum impurity problems can be solved using the numerical renormalization group (NRG), which involves discretizing the free conduction electron system and mapping to a `Wilson chain'. It was shown recently that Wilson chains for different electronic species can be interleaved by use of a modified discretization, dramatically increasing the numerical efficiency of the RG scheme [Phys. Rev. B 89, 121105(R) (2014)]. Here we systematically examine the accuracy and efficiency of the `interleaved' NRG (iNRG) method in the context of the single impurity Anderson model, the two-channel Kondo model, and a three-channel Anderson-Hund model. The performance of iNRG is explicitly compared with `standard' NRG (sNRG): when the average number of states kept per iteration is the same in both calculations, the accuracy of iNRG is equivalent to that of sNRG but the computational costs are signifficantly lower in iNRG when the same symmetries are exploited. Although iNRG weakly breaks SU(N) channel symmetry (if present), both accuracy and numerical cost are entirely competitive with sNRG exploiting full symmetries. iNRG is therefore shown to be a viable and technically simple alternative to sNRG for high-symmetry models. Moreover, iNRG can be used to solve a range of lower-symmetry multiband problems that are inaccessible to sNRG.

description: In this paper the environmental and energy performance of PV systems as part of a building is
investigated, following the assessment methods in the latest Dutch building code. It is shown that the use of two
separate assessments of materials environmental performance next to energy performance can form a stumbling block
for PV acceptance by building designers. This is illustrated in a case study for a house with a 3 kWp PV system in 3
solar technology variants: crystalline silicon, cadmium telluride and a-Si foil. An improved assessment is presented
which shows the integral environmental impacts of materials and energy over the building life cycle. With this
integrated method the environmental benefits of PV on a building are clearly shown. Furthermore we discuss the
need for good quality LCA data on state-of the-art PV components in order to provide building designers with the
right tools and data for optimal building design, including PV systems.

description: Exponential integrators have been introduced as an efficient alternative to explicit and implicit methods for integrating large stiff systems of differential equations. Over the past decades these methods have been studied theoretically and their performance was evaluated using a range of test problems. While the results of these investigations showed that exponential integrators can provide significant computational savings, the research on validating this hypothesis for large scale systems and understanding what classes of problems can particularly benefit from the use of the new techniques is in its initial stages. Resistive magnetohydrodynamic (MHD) modeling is widely used in studying large scale behavior of laboratory and astrophysical plasmas. In many problems numerical solution of MHD equations is a challenging task due to the temporal stiffness of this system in the parameter regimes of interest. In this paper we evaluate the performance of exponential integrators on large MHD problems and compare them to a state-of-the-art implicit time integrator. Both the variable and constant time step exponential methods of EpiRK-type are used to simulate magnetic reconnection and the Kelvin--Helmholtz instability in plasma. Performance of these methods, which are part of the EPIC software package, is compared to the variable time step variable order BDF scheme included in the CVODE (part of SUNDIALS) library. We study performance of the methods on parallel architectures and with respect to magnitudes of important parameters such as Reynolds, Lundquist, and Prandtl numbers. We find that the exponential integrators provide superior or equal performance in most circumstances and conclude that further development of exponential methods for MHD problems is warranted and can lead to significant computational advantages for large scale stiff systems of differential equations such as MHD.

description: A compound Poisson process whose parameters are all unknown is observed at finitely many equispaced times. Nonparametric estimators of the jump and Lévy distributions are proposed and functional central limit theorems using the uniform norm are proved for both under mild conditions. The limiting Gaussian processes are identified and efficiency of the estimators is established. Kernel estimators for the mass function, the intensity and the drift are also proposed, their asymptotic properties including efficiency are analysed, and joint asymptotic normality is shown. Inference tools such as confidence regions and tests are briefly discussed.

description: By a market study and economic modeling we studied the suitability, limitations and opportunities of
BIPV products in the Dutch terraced houses renovation sector. A large share of Dutch terraced houses is in the
possession of social housing organizations. The combined approach of roof renovation, roof insulation and PV
application can lower the energy index of these houses by more than 1.0 and realize a four energy label improvement
steps (e.g. from label E to label A). Approaches that combine roofing, insulation and PV functionalities in one
product only need to access the roof once and can cut the total system cost by 20%. The annual energy savings on
heating and electricity by the combined product add up to 1500 euro for a typical household. An internal rate of
return on the initial investment of almost 10% can be achieved. The renovation repays itself in about 12 years.
Finally, we describe the development of a prototype BIPV roof that is specifically developed for the Dutch terraced
housing renovation market and indeed combines the roofing, insulation and PV functionalities.

description: Many automated system analysis techniques (e.g., model checking, model-based testing) rely on first obtaining a model of the system under analysis. System modeling is often done manually, which is often considered as a hindrance to adopt model-based system analysis and development techniques. To overcome this problem, researchers have proposed to automatically "learn" models based on sample system executions and shown that the learned models can be useful sometimes. There are however many questions to be answered. For instance, how much shall we generalize from the observed samples and how fast would learning converge? Or, would the analysis result based on the learned model be more accurate than the estimation we could have obtained by sampling many system executions within the same amount of time? In this work, we investigate existing algorithms for learning probabilistic models for model checking, propose an evolution-based approach for better controlling the degree of generalization and conduct an empirical study in order to answer the questions. One of our findings is that the effectiveness of learning may sometimes be limited.

description: Façades are the central element in the design and architectural definition of contemporary buildings.
Several solutions, with different aesthetical appeal, perform the finishing materials of existing building and new
constructions. A sustainable design process today is intended to produce high-performance buildings that are energyefficient,
healthy and economically feasible, by wisely using renewable resources to minimize the impact on the
environment and to reduce, as much as possible, the energy demand. For this reason, the facade system plays an
important role for achieving these energy and environmental goals and Photovoltaic can play a leading role in this
challenge. Relying on a vast database of products and building examples, collected in different research projects, a
multi-criteria analysis has been performed to compare BIPV solutions with other technological possibilities for
façade (either traditional than innovative), in terms of technological, architectural, energetic, environmental and
economic requirements. As this study demonstrates, PV will be able to become an affordable alternative to
conventional façades since a more precise information and a common language will be implemented and shared.

The document, commissioned by British Prime Minister Winston Churchill, is drawn up by an English military commission (British Committee on the Preservation and Restitution of Works of Art, Archives and Other Material in Enemy Hands) whose precise task is to assess the damage caused. to the Italian cultural heritage during the war years. This is an editorial initiative that is part of the work of the Allied Commission for Monuments, Fine Arts and Archives (MFAA), a commission created by the American and British governments in the spring of 1943, shortly before the Allied landing in Sicily, to the protection of works of art and archives in Europe at war.

description: Vehicle-integrated Photovoltaics (ViPV) is on the verge to become a feasible solution to provide
additional electrical energy to the electrical power supply system of standard road vehicles. Moreover, by relieving
the alternator and combustion engine with this extra energy source, fuel consumption can be reduced. Compared to
fix-installed PV, the integration into vehicles bears great advantages in terms of temperature reduction from headwind
cooling. Our study deals with the effect of convective heat losses on the thermal and electrical behaviour of
ViPV systems. Based on dynamic-simulations the temperature and performance behaviour of different PV
technologies were evaluated for various wind speeds. Four different ViPV operation scenarios were analysed for
different initial temperature conditions. Our results show that already low vehicle speeds are sufficient enough to
reduce the module temperature significantly (one third for e.g. mc-Si). In line with the temperature reduction, also the
PV performance increases. In this work, we discuss the dependence of ViPV system performance on the heat loss
from forced convection – in the form of vehicle head-wind. The outcome is critically analysed.

description: Against the background of reduced PV feed-in tariffs in many important European countries and
increasing problems with grid stability at PV peak power times due to tremendously growing capacities, electricity
storage and self-consumption of PV power has emerged to be a crucial topic for the PV community. One promising
approach lies in thermal storage of PV power in the HVAC supply for buildings. Besides cost-effective but lowefficiency
ohmic heaters, a new development is compression heat pumps and chillers directly operated with PV.
However, if directly coupled to a PV-plant, commercially available heat pump systems suffer from severe control
problems due to highly transient PV power supply. Both On-Off control and combinations of scroll compressor and
frequency inverter have a more or less limited control range. In the present study, a novel heat pump set-up with swashplate
compressor will be presented, offering a number of advantages: other than with conventional single-degree-offreedom
on-off or FI-scroll control systems, rpm plus cylinder stroke can be actively controlled. At frequently occurring
solar part load conditions coming mostly parallel with elevated heating demand, swash-plate compressors offer a higher
efficiency factor at a much wider control range. The study is providing details on the novel heat pump set up with swashplate
compressor together with experimental results on part-load efficiency as well as step function response on sudden
PV power increase or decrease. Based on these results, theoretical investigations yield a first potential analysis of the
novel system compared to a conventional FI-scroll compressor set-up. A yearly simulation showed improvement
potentials of 35 % in PV self-consumption and 30 % in solar heat supply.

description: The mitochondrial voltage-dependent anion channel 1 (VDAC1) plays a central role in metabolism and apoptosis, which makes it a promising therapeutic target. Nevertheless, molecular mechanisms governing VDAC1 functioning remain unclear. Small-molecule ligands specifically interacting with the channel provide an attractive way of exploring its structure-function relationships and can possibly be used as founding stones for future drug-candidates. While around 30 VDAC1 ligands have been identified over the years, various techniques have been used by research teams, making a fair and direct comparison between compounds impossible. To tackle this issue, we performed ligand-binding assays on a representative set of seventeen known VDAC1 ligands using nano-differential scanning fluorimetry and microscale thermophoresis. While all the compounds have been confirmed as VDAC1 ligands by at least one method, combining both technologies lead to the selection of four molecules (cannabidiol, curcumin, DIDS and VBIT4) as chemical starting points for future design of VDAC1 selective ligands.
