Controlling Energy-Efficient Buildings in the Context of Smart Grid: A Cyber Physical System Approach

Controlling Energy-Efficient Buildings in the Context of Smart Grid: A Cyber Physical System Approach by Mehdi Maasoumy Haghighi Doctor of Philosophy in Engineering Mechanical Engineering University of California, Berkeley Professor Alberto Sangiovanni-Vincentelli, Chair The building sector is responsible for about 40% of energy consumption, 40% of greenhouse gas emissions, and 70% of electricity use in the US. Over 50% of the energy consumed in buildings is directly related to space heating, cooling and ventilation. Optimal control of heating, ventilation and air conditioning (HVAC) systems is crucial for reducing energy consumption in buildings. We present a physics-based mathematical model of thermal behavior of buildings, along with a novel Parameter Adaptive Building (PAB) model framework to update the model parameters, as new measurements arrive, to reduce the model uncertainties. We then present a Model Predictive Control (MPC), and a Robust Model Predictive Control (RMPC) algorithm and a methodology for selecting a controller type, i.e. RMPC or MPC, versus Rule Based Control (RBC) as a function of model uncertainty. We then address the “Cyber-Physical” aspect of a building HVAC system in the design flow. We present a co-design framework that analyzes the interaction between the control algorithm and the embedded platform through a set of interface variables, and demonstrate how the design space is explored to optimize the energy cost and monetary cost, while satisfying the constraints for occupant comfort level. The last part of this dissertation is centered on the role of smart buildings in the context of the smart grid. Commercial buildings have inherent flexibility in how their HVAC systems consume electricity. We first propose a means to define and quantify the flexibility of a commercial building. We then present a contractual framework that could be used by the building operator and the utility company to declare flexibility on one side and reward structure on the other side. We also present a control mechanism for the building to decide its flexibility for the next contractual period to maximize the reward. We also present a Model Predictive Control (MPC) scheme to direct the ancillary service power flow from buildings to improve upon the classical Automatic Generation Control (AGC) practice. We show how constraints
Dynamic Link Improvements using a Reconfigurable Reflector Antenna

This paper demonstrates that adapting the reflector surface shape of a spacecraft antenna according to the actual weather situation can reduce the transponder power margin by as much as 6 dB. The computer time required to calculate a new scenario is about 30 seconds. The range of the setting of the actuators to obtain the different surface shapes is within ±10 mm for a typical antenna operating at 12 GHz. (4 pages)
THESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY A Large Eddy Simulation Based Fluid-Structure Interaction Methodology with Application in Hydroelasticity

The phenomenon of hydroelasticity is a subarea of Fluid-Structure Interaction (FSI) and of major importance in many engineering applications related to hydrodynamics and naval architecture e.g. wave-induced vibrations, such as springing, whipping and slamming, propeller singing, composite propellers or turbines, acoustic signatures from naval vessels, highly loaded thin propeller blades, and cavitation erosion. Some of these phenomena can be assessed with reasonable reliability, but in cases where mediumto small-scale flow features are important the computational models need to be further developed to improve predictive capability and enable new conceptual designs. The work presented in this thesis has this kind of development as objective and a method capable of providing hydroelasticity predictions based on LES is presented and validated. The problem is particularly challenging as the densities of the fluid and the structure are comparable and an implicit coupling is thus needed to ensure a stable solution procedure. Furthermore, LES is not well established in the FSI context and especially not within the area of hydroelasticity. High resolution of the computation is necessary and the algorithm needs to run efficiently on large parallel computer systems. Reliable results also include predicting the correct separation pattern, in general on smoothly curved geometries. To address this a validation of LES in terms of predicting the correct separation pattern was performed and presented here, including also the development and validation of a LES turbulence trip model. The results presented can be divided into three parts, firstly the prediction and validation of open separation phenomena around a prolate spheroid, secondly the prediction and validation of the flow around an oscillating cylinder and thirdly the development of a fluid-structure interaction methodology for hydrodynamic applications and corresponding prediction and validation of the deformation of a flexible hydrofoil. The results all show a good agreement with experimental data, thus supporting the validity of the fluid-structure interaction methodology for hydroelastic applications presented within the scope of this thesis. Finally, the parallel performance of the implementation is analyzed through both weak and strong scaling and found to be satisfactory.
Response to Referee #2

This study conducts a signal detection analysis for global changes in mean and extreme precipitation using three observational datasets and CMIP6 multi-model outputs. The authors apply a ridge regression (RR) method to construct fingerprints, which helps increase a signal-to-noise ratio of precipitation change patterns. Results show a robust detection of anthropogenic signals in all observations for both mean and extreme precipitation even when removing global mean trends, further supporting the human-induced intensification of global hydrological cycle. I find this paper very well written with sufficient details provided about methods as well as various sensitivity tests and therefore suggest publication after addressing some minor issues.
A thermistor based sensor for flow measurement in water

There is limited experimental data describing the mixing processes and coherent velocity structures near the surface of the ocean. These play an important part in the interactions between the atmosphere and the ocean and thus affect the climate of the earth. A robust, low cost thermistor based sensor suitable for use in the detection and quantification of velocity structures has been designed and developed. The flow sensor, a thermal anemometer, consists of a self-heated thermistor that is maintained at constant temperature using a feedback control circuit. The thermistor is exposed to the moving fluid and the heat transfer from it is a function of the velocity of the fluid. The sensor has been interfaced with a PC to facilitate data acquisition. A tow tank calibration and testing facility also interfaced to a PC was developed. The sensor is compensated for changes in ambient fluid temperature, which is a major problem for all thermal anemometers that operate in water. The calibration relation that is normally used for thermistor anemometers has been improved upon and gives better results than any found in the literature. In order to provide electrical isolation from the water the sensor was protected with an insulating coating. The effect of coating thickness and the type of coating used on sensor performance was investigated. It was found that a polymer coating resulted in a sensor that did not show any appreciable drift due to sensor contamination over a number of months. This is a significant improvement over glass coated hot film sensors, which are widely used for velocity measurements in water and previously developed thermistor based sensors. The effect of various control circuit parameters on the frequency response of the sensor was determined and these parameters were tuned to give maximum frequency response A procedure for easily replacing broken/damaged sensors in the field was also developed.

Online Programming Semantic Error Feedback using Dynamic Template Matching

Many of automated computer programming feedback is generated based on static template matching that need to be provided by the experts. This research is focusing on developing an automated online programming semantic error feedback by using dynamic template matching models based on students’ correct answers submission. Currently, there is a lack of research using dynamic template matching model due to their complexity and varies in terms of programming structure. To solve the formulation of the dynamic templates, a new automated feedback model using front and rear n-gram sequence as the matching technique was developed to provide feedback to students based on the missing structure of the best-matched template. We have tested 60 student’s Java programming answers on 3 different types of programming questions using all the dynamic templates randomly chosen for each student. An expert was assigned to manually match the student’s answer with the 3 randomly chosen templates. The result shows that 80% of the best-matched templates for each student using the technique were similarly chosen by the expert. Based on the matched template, the student will be given feedback notifying the possible next programming instruction that can be included in the answer to get it correct as was achieved by the template. This model can contribute to automatically assist students in answering computational programming exercises. Keywords—Dynamic; feedback; online programming; semantic error; template matching
An exploratory study of the development of virtual learning environments for adult literacy education

This thesis fundamentally was derived from the increasing demand for more flexible models of adult literacy education, within a wider agenda that aimed to improve accessibility to a wide range of users with different learning styles and to promote the use of Information and Communication Technology (ICT) as a necessary life-skill. A study in 1997 by the Organisation for Economic Co-operation and Development, OECD, reported that one in four Irish adults lacked the basic literacy skills needed to function in society. In 2001, anecdotal evidence suggested that as low as four percent o f Irish adults with literacy problems were receiving literacy tuition and support in established adult literacy centres in Ireland. A proposed solution to the problems of access and support, retention of anonymity and provision of flexibility in literacy education involved the establishment of virtual learning environments. The focus of this research was to present a synthesis of developments in the area of the adult literacy tuition and support, and, furthermore, to ascertain whether there existed elements of a ''workable process’ for designing and integrating technology in literacy programmes that could be utilised in future developments of virtual learning environments. The focus of this investigation was primarily on design team and stakeholders engagement in the software design and development processes, as opposed to an investigation into the suitability of the learning processes adopted from an instructional perspective. The findings of this research present a four-level 'workable process' that can be used to guide design teams through the process of software development. A contextual review of the area in which the software is to be embedded, and an analysis of the needs of the various participants, is considered pivotal to the success of this four-level process. The findings also emphasise the importance of collaborative teamwork, and furthermore the engagement of design team members in a dialectical process in consensus formation, as being critical to the successful implementation of this 'workable process'.
Grumman WS33 wind system: prototype construction and testing, Phase II technical report

The prototype fabrication and testing of the 8 kW small wind energy conversion system are reported. The turbine is a three-bladed, down-wind machine designed to interface directly with an electrical utility network. The machine as finally fabricated is rated at 15 kW at 24 mpH and peak power of 18 kW at 35 mph. Utility compatible electrical power is generated in winds between a cut-in speed of 9 mph and a cut-out speed of 35 mph by using the torque characteristics of the unit's induction generator combined with the rotor aerodynamics to maintain essentially constant speed. Inspection procedures, pre-delivery testing, and a cost analysis are included.
Service Design for Six Sigma: A Roadmap for Excellence

This book introduces Design for Six Sigma (DFSS), an easy-to-master, yet highly effective data-driven method that prevents defects in any type of service process. The particular focus of this publication is service DFSS, which leads to what the authors term "a whole quality business," one that takes a proactive stance and gets things right the first time. Not only does the whole quality business produce a high-quality product and offer high-quality services, but it also operates at lower cost and higher efficiency, throughout the entire life cycle, than its competitors because all the links in the supply chain are optimized
Model-based control of venetian blinds

Commercial and institutional buildings are being designed with increased transparent areas of the facade. Provision of views to the exterior is desirable, but more importantly, human health and productivity benefits may result from well day-lit interior spaces. The increased use of natural light, coupled with daylight responsive lighting systems, can reduce the peak electrical load and internal heat gains caused by artificial lighting. However, excessive transmission of solar irradiance can result in a net increase in energy consumption required for cooling, and may also affect the visual comfort of occupants. Manually operated shading devices are commonly used to deal with this problem, though their control is generally not optimal. This thesis investigates the potential of an automated model-based control strategy for diffuse reflecting venetian blinds. Radiosity theory was used to numerically approximate the transmittance of a blind and glazing system for clear-sky conditions, and to determine the venetian slat angle required to maintain favourable transmission values based on the HVAC demand and the visual comfort of the building occupants. Experimental measurements were carried out using a controlled motorized venetian blind installed on a clear glass window unit in a small-office space. The daylight transmission of the system was quantified and compared to the modelled prediction. A dimmable luminaire was also installed in this zone to determine the electric lighting energy savings possible in perimeter zones with the blinds continuously controlled to intercept direct sun rays
Multi-domain text classification for unit selection Text-to-Speech synthesis

This paper presents a new approach for designing a concatenative text-to-speech (TTS) system based on multi-domain unit selection. The method achieves good synthetic quality with reasonable computational cost for a general-purpose TTS system. The architecture of the multi-domain database and the text classification algorithm for domain assignment are the basis of the method. The performance of the adjusted text classification algorithm for the multi-domain TTS aim is analyzed in several encouraging experiments.
Advanced techniques for the determination of sound spatialization in italian opera theatres

As Italy possesses a rich heritage of Opera houses and since, owing to the period in which they were built, they were not planned for electroacoustical amplification systems and the quality of the listening conditions in the theatres was still wholly due to their spatial characteristics, the materials and the techniques used to build them, the Teatro Comunale of Bologna was chosen for this research. An experimental measuring campaign was conducted in this late 18th century "Italian-style" theatre so as to define a map of the impulse responses (IR) able to significantly represent the acoustics perceived by the audience seated in the stalls or balconies. Using the geometric and constructional data, a three-dimensional model of the theatre was then made and used to numerically simulate the acoustic properties in the theatre and, after appropriate calibration, the respective impulse responses were calculated in the same points as where the measurements had been taken in the experimental campaign. Lastly, the method for auralising an anechoic signal was used for qualitatively comparing the simulation of the theatre's acoustic response. This was done by calculating an IR from the experimental data and extrapolating an IR from the numeric model.
Balanced gene retention, transcription and methylation levels between subgenomes produced by soybean-specific paleo-tetraploidization

BackgroundPolyploidization creates duplicated sets of genomes in a plant. Dominance by a subgenome is often observed in a polyploid species. Here, we studied the duplicated genomic regions in soybean, which was affected by a tetraploidization 13 million years ago.ResultsBy referring to eudicot relatives, we detailed that duplicated genes are retained in a balanced manner among homoeologs. Moreover, we found that duplicated genes in colinearity in extant genome are expressed at balance. Notably, the DNA methylation patterns of duplicated genes shared similar methylation levels among three different soybean lines (W931A, WR016, and ZAYOU1), suggesting that either the epigenetic information could be maintained transgenerationally for millions of years or homoeologs in this paleo-autopolyploid species have similar methylation patterns under similar environment.ConclusionsThese findings support the paleo-autotetraploidy of soybean. We proposed that, if taking maize as a model plant for studying paleo-allotetraploids, soybean is a model plant for studying paleo-autotetraploids.
Particulate Generation During Disruption Simulation on the SIRENS High Heat Flux Facility

Successful implementation of advanced electrical power generation technology into the global marketplace requires at least two fundamental ideals: cost effectiveness and the guarantee of public safety. These requirements can be met by thorough design and development of technologies in which safety is emphasized and demonstrated. A detailed understanding of the many physical processes and their synergistic effects in a complicated fusion energy system is necessary for a defensible safety analysis. One general area of concern for fusion devices is the production of particulate, often referred to as dust or aerosol, from material exposed to high energy density fusion plasma. This dust may be radiologically activated and/or chemically toxic, and, if released to the environment, could become a hazard to the public. The goal of this investigation was to provide insight into the production and transport of particulate generated during the event of extreme heat loads to surfaces directly exposed to high energy density plasma. A step towards achieving this goal was an experiment campaign carried out with the Surface InteRaction Experiment at North Carolina State (SIRENS), a facility used for high heat flux experiments. These experiments involved exposing various materials, including copper, stainless steel 316, tungsten, aluminum, graphite (carbon), and mixtures of carbon and metals, to the high energy density plasma of the SIRENS source section. Material mobilized as a result of this exposure was collected from a controlled expansion chamber and analyzed to determine physical characteristics important to safety analyses (e.g., particulate shape, size, chemical composition, and total mobilized mass). Key results from metal-only experiments were: the particles were generally spherical and solid with some agglomeration, greater numbers of particles were collected at increasing distances from the source section, and the count median diameter of the measured particle size distributions were of similar value at different positions in the expansion chamber, although the standard deviation was found to increase with increasing distances from the source section, and the average count median diameters were 0.75 micron for different metals. Important results from the carbon and carbon/metals tests were: particle size distributions for graphite tests were bi-modal (i.e. two distributions were present in the particle population), particles were generally smaller than those from metals-only tests (average of 0.3 micron), and the individual particles were found to contain both carbon and metal material. An associated step towards the goal involved development of an integrated mechanistic model to understand the role of different particulate phenomena in the overall behavior observed in the experiment. This required a detailed examination of plasma/fluid behavior in the plasma source section, fluid behavior in the expansion chamber, and mechanisms responsible for particulate generation and growth. The model developed in this…
