Renewable energy, distributed generation, and micro-grid technology have been widely concerned for a long time. The traditional grid-connected inverter control strategy does not take into account the problem of inertia which is short and fast to cause the frequency change. The virtual synchronous generator control strategy is adopted to simulate the synchronous generator characteristics, which enhanced the inertia and damp of the system. For the micro-grid of wind power grid-connected, the storage battery is arranged on the AC side of the permanent magnet direct-drive wind turbine, and the model of the virtual synchronous generator is established. Thus the grid-connected performance of large-scale wind farm is improved. Here, the effect of moment of inertia in the virtual synchronous generator and the grid-connected regulation of virtual synchronous generator are verified by using PSCAD/EMTDC. The simulation results show that the grid-connected inverter controlled by the virtual synchronous generator is approximately equivalent to the synchronous generator in external characteristic. The grid-connected inverter based virtual synchronous generator control has a beneficial to adjust frequency and voltage, and can enhance the standby inertia of new energy and grid power generation

The virtual synchronous generator (VSG) technology of inverter is widely used to provide the inertia and damping support for power system. However, an additional measurement device PLL (phase-locked loop) is required in the virtual synchronous generator grid connection to track the voltage phase, amplitude, and frequency, which restricts the flexible output of the distributed power generation system. To tackle this challenge, a method for grid-connected control of virtual synchronous generator based on virtual impedance is proposed. It is assumed that there is a virtual power exchange between the synchronous machine and the power grid when the virtual synchronous generator is off-grid, the virtual impedance is developed to calculate the virtual current, and when the virtual current is zero, the output voltage of the VSG can be synchronized with the voltage of the power grid, thereby seamlessly switching between off-grid and grid-connected VSG. A semiphysical simulation platform is built based on RT-LAB; simulation and experimental results show that the proposed grid synchronization control strategy of the VSG can achieve seamless transform between different VSG modes, which is simpler than the conventional synchronization control, while having a good active and reactive power tracing performance.

This paper describes a series of our studies for developing functions for robots to better interact with humans, especially in the welfare field. The caregiver support robot is proposed to help caregivers in the welfare field and functions related to realizing affective behavior were studied. We believe such robotmust understand human emotion state, have own virtual emotion state and be able to express emotion in order to behave affectively. The Virtual Kansei (VK) was proposed to answer this set of requirements and various elements of VK were developed. The VK consists of three parts; the Kansei detector, the Kansei generator and the Kansei expressive regulator. The Kansei detector detects human partner’s emotion state using facial images, voice sounds and body movements. The Kansei generator generates human-like virtual emotion for robots. We devised a mimicking approach in developing the generator where emotion distances are defined and are used in learning and evaluating the generator. The Kansei expressive regulator makes the robot behave emotionally in executing everyday tasks. It modulates the basic robot motion according to the generated virtual emotion. This paper focuses on the concept and the relationship of these elements.

In this paper, virtual synchronous converter (VSCon) is modelled which behaves as synchronous generator including its all real-time characteristics in operating inverter. This VSCon is used to synchronize grid and inverter while integrating distributed generated power to microgrids. The frequency and voltage synchronization can be controlled by using synchronous generator mathematical model is installed into the inverter. The whole unit of VSCon operated is simulated in Matlab/Simulink for observing all consequences for synchronizing voltage, frequency and phase-angle. It is verified that the next generation energy resources can be integrated into microgrid making synchronization grid-inverter using VSCon. The simulation results are given to verify the concept of modelling VSCon functioning inverter as a synchronous generator.

Besides achieving an optimal scheduling generator, the operation safety of the generator itself needs to be focused on. The development of the virtual visualization of a generator capability curve simulation to visualize the operation condition of a generator is proposed in this paper. In this paper, a neural network is applied to redraw the original generator’s capability curve. The virtual visualization of a generator’s capability curve can simulate the generator’s operating condition considering the limitation of the constraints on the various elements of the generator. Furthermore, it is able to show the various possibilities that occur in the operation of a generator in reality, and it can even simulate special conditions which are based on various conditions.

Electrical Engineering M.S.E.E. In conventional centralized power systems, power is generated mostly by large synchronous generators (SGs), where the frequency of the grid depends on the rotational frequency of the prime mover. If there are any sudden changes in the load, the rotor inertia property restrains the changes in frequency and keeps the system stable. During transient periods, rotor kinetic energy of the rotor is injected into the grid to balance power supply between generation and load. With the recent high penetration of renewable energy sources (RES), the power grid is undergoing structural changes with an increased inverter-based distributed generation. Since inverter based power sources do not have inertia as conventional synchronous machines (SM), high penetration of inverters may cause instability and sharp voltage fluctuations in the grid. If inverter based power sources could be configured as regular SM by introducing virtual inertia and damping property, many of the problems, such as frequency regulation, islanded operation, and parallel operation of inverter-based DGs will be resolved. This thesis investigates mathematical modeling and control of VSG’s to emulate the inertia and damping property of SMs. Simulation results are presented on the modeling and closed-loop performance of VSGs for an island microgrid.

This research addresses some of the difficulties faced when operating voltage controlled inverters with synchronous generators in microgrids. First, an overview of microgrid value propositions is provided, and the problems faced when attempting to use microgrids to provide improved power quality are discussed. Design considerations for different types of microgrids are provided to enable microgrids to deliver the desired functionality without adding unnecessary cost. The main body of this research investigates the poor transient load sharing encountered between voltage controlled inverters and synchronous generators in islanded operation. Poor transient load sharing results in high peak inverter rating requirements and high cost. The tradeoff between power quality and power sharing is highlighted, and methods to improve transient load sharing are proposed. The use of current limiting to protect inverters during faults and overloads is also investigated. Stability problems are identified when using simple inverter current limiting methods when operating in parallel with synchronous generators. Virtual impedance current limiting is proposed to improve transient stability during current limiting. The methods proposed in this thesis for mitigating inverter overloads and faults will allow for more reliable and cost effective application of inverter based distributed energy resources with synchronous generators in microgrids.

Nowadays, the number of processors integrated on system-on-chip (SoC) increases rapidly and makes multiprocessor system-on-chip design (MPSoC) a regular feature of the embedded system. [25] To support the communication between several homogeneous or heterogeneous processors a communication infrastructure, Networkon-Chip (NoC) technology was raised more than ten years ago. Decades of research provides the NoC area with an increasingly sophisticated knowledge system. A wide variety of NoC systems are developed and evaluated. To simplify the design flow of NoC systems, a NoC System Generator Tool (NGS) [23] [25] [26] is developed by researchers of Royal Institute of Technology. It aims to generate NoC systems with different topology, size, processing elements, and network protocols on FPGAs. NoC routers are central parts in modelling NoC communications. In the current version, Nostrum router is used as only supported communication backbone. This project starts from an analysis to NoC theory and steps into important aspects related to NoC router design to implement a register transfer level (RTL) synthesizable wormhole (WH) router in VHDL for NGS tool. WH router is a comparatively old however widely used NoC router structure. A Virtual-Channel (VC) based flow control is adopted in this design to improve the performance. After implementing the WH router, functional tests on a single router, 2×2 and 3×3 WH Router based network are performed on Modelsim 10.0. VHDL test benches with “textio” operations are prepared to generate a clear report to reveal packets’ transfer details in the network. The router and 2×2 network is synthesized on Quartus II for the Cyclone IV E FPGA family to compare the area overhead with Nostrum NoC.

As the backbone of many computing environments today, it is important that process virtual machines be both performant and robust in mobile, personal desktop, and enterprise applications. This thesis focusses on code generation within these virtual machines, particularly addressing situations where redundant work is being performed. The goal is to exploit information sharing in order to improve the performance and robustness of virtual machines that are accelerated by native code generation. First, the thesis investigates the potential to share generated code between multiple threads in a dynamic binary translator used to perform instruction set simulation. This is done through a code generation design that allows native code to be executed by any simulated core and adding a mechanism to share native code regions between threads. This is shown to improve the average performance of multi-threaded benchmarks by 1.4x when simulating 128 cores on a quad-core host machine. Secondly, the ahead-of-time code generation system used for executing Android applications is improved through the use of profiling. The thesis investigates the potential for profiles produced by individual users of applications to be shared and merged together to produce a generic profile that still provides a lot of benefit for a new user who is then able to skip the expensive profiling phase. These profiles can not only be used for selective compilation to reduce code-size and installation time, but can also be used for focussed optimisation on vital code regions of an application in order to improve overall performance. With selective compilation applied to a set of popular Android applications, code-size can be reduced by 49.9% on average, while installation time can be reduced by 31.8%, with only an average 8.5% increase in the amount of sequential runtime required to execute the collected profiles. The thesis also shows that, among the tested users, the use of a crowd-sourced and merged profile does not significantly affect their estimated performance loss from selective compilation (0.90x-0.92x) in comparison to when they they perform selective compilation with their own unique profile (0.93x). Furthermore, by proposing a new, more powerful code generator for Android’s virtual machine, these same profiles can be used to perform focussed optimisation, which preliminary results show to increase runtime performance across a set of common Android benchmarks by 1.46x-10.83x. Finally, in such a situation where a new code generator is being added to a virtual machine, it is also important to test the code generator for correctness and robustness. The methods of execution of a virtual machine, such as interpreters and code generators, must share a set of semantics about how programs must be executed, and this can be exploited in order to improve testing. This is done through the application of domain-aware binary fuzzing and differential testing within Android’s virtual machine. The thesis highlights a series of actual code generation and verification bugs that were found in Android’s virtual machine using this testing methodology, as well as comparing the proposed approach to other state-of-the-art fuzzing techniques.

Atualmente, as tecnologias disponíveis para a fabricação de dispositivos eletrônicos permitem um alto grau de integração de semicondutores. Entretanto, esta integração torna o projeto, a verificação e o teste de circuitos integrados mais difíceis. Normalmente, o projeto de circuitos integrados é consideravelmente afetado com a diminuição do tamanho dos dispositivos eletrônicos em tecnologias sub-micrônicas. Conseqüentemente, os projetistas adotam metodologias rígidas para produzir circuitos de alta qualidade em tempo razoável. Ferramentas de auxílio ao projeto de circuitos eletrônicos são utilizadas para automatizar algumas das etapas do projeto, ajudando o projetista a encontrar boas soluções rapidamente. Uma das tarefas mais difíceis no projeto de circuitos integrados é fazer com que o circuito respeite as restrições de atraso. Isto depende de várias etapas do processo de síntese. Em metodologias baseadas em bibliotecas de células, isto está diretamente relacionado ao algoritmo para mapeamento tecnológico e as células disponíveis na biblioteca. O atraso de cada célula depende do tamanho dos transistores e da topologia da rede de transistores. Isso determina as características de atraso, potência e área de uma célula. O mapeamento tecnológico define as principais características estruturais do circuito, principalmente em área, potência e atraso. A qualidade do circuito mapeado depende das células disponíveis na biblioteca de células. Este trabalho propõe um novo método para mapeamento com bibliotecas virtuais para redução de atraso em circuitos combinacionais. Ambos os algoritmos baseiam-se em uma topologia de células capaz de implementar funções Booleanas com cadeias mínimas de transistores em série. Os algoritmos reduzem o número de transistores em série do caminho mais longo do circuito, considerando que cada célula é implementada por uma rede de transistores que obedecem um número máximo de transistores em série. O número de transistores em série é calculado de forma Booleana, garantindo que este seja o número mínimo necessário para implementar a função lógica da célula. Os algoritmos estão integrados a um gerador de células que utiliza tal topologia e realiza o dimensionamento dos transistores. Ganhos significativos podem ser obtidos combinando estas duas técnicas em uma ferramenta para mapeamento tecnológico. Currently, microelectronic technologies enable high degrees of semiconductor integration. However, this integration makes the design, verification, and test challenges more difficult. The circuit design is often the first area under assault by the effects of aggressive scaling in deep-submicron technologies. Therefore, designers have adopted strict methodologies to deal with the challenge of developing high quality designs on a reasonable time. Electronic Design Automation tools play an important role, automating some of the design phases and helping the designer to find a good solution faster. One of the hardest challenges of an integrated circuit design is to meet the timing requirements. It depends on several steps of the synthesis flow. In standard cell based flows, it is directly related to the technology mapping algorithm and the cells available in the library. The performance of a cell is directly related to the transistor sizing and the cell topology. It determines the timing, power and area characteristics of a cell. Technology mapping has a major impact on the structure of the circuit, and on its delay and area characteristics. The quality of the mapped circuit depends on the richness of the cell library. This thesis proposes two different approaches for library-free technology mapping aiming delay reduction in combinational circuits. Both algorithms rely on a cell topology able to implement Boolean functions using minimal transistors stacks. They reduce the overall number of serial transistors through the longest path, considering that each transistor network of a cell has to obey to a maximum admitted chain. The mapping algorithms are integrated to a cell generator that creates cells with minimal transistor stacks. This cell generator is also in charge of performing the transistor sizing. Significant gains can be obtained in delay due to both aspects combined into the proposed mapping tool.

Annotation:

Transport of solid particles in a slit virtual impactor has been analyzed using visualization techniques. Particle trajectories were observed using laser-induced fluorescence of monodisperse particles seeded in the virtual impactor flow. It was observed from these trajectories that for smaller inertia particles essentially followed the flow streamlines, whereas higher inertia particles tend to deflect from their initial streamlines. These transport characteristics were used to determine particle collection efficiency curves, and the percentage of defect particle transmission, particles transmitted to the major flow that are well beyond the experimentally determined 50% cutoff. Defect percentages were found to be in good agreement with those based on a local stokes number approach, an analytical model using a converging flow velocity profile. It was hypothesized that these defects occur by virtue of larger particles passing through the near wall flow region and consequently transported to the major flow. The trajectories of such defect occurrences clearly show that these particles originated in the near wall region. Performance at higher mass loadings was evaluated using a background dust matrix generated by a turntable aerosol generator. At high mass loadings, clogging of the slit led to the deterioration of the impactor's performance. The time taken to clog the silt was estimated by modeling the slit edge as a single filter fiber of rectangular cross section with the primary mechanism of filtration being interception and was found to be in good agreement with the experimental data. Elimination of defect transmission and clogging would be possible by the provision of a sheath airflow, which ensures that the near wall regions are free of particles.

Les sources classiques d'énergie distribuée (DER) fournissant de l'énergie aux microgrids (généralement des groupes électrogènes diesel) sont progressivement remplacées par les onduleurs basés sur des sources d'énergie renouvelables (RES). Cependant, l'intermittence des sources d'énergie renouvelables pose des problèmes de stabilité majeurs, en particulier dans le contexte des microgrids, notamment parce que ces sources diminuent l'inertie disponible du réseau. Par conséquent, les stratégies de contrôle traditionnelles pour les onduleurs, qui interfacent les différents DER connectés au microgrid, doivent être adaptées.Le générateur virtuel synchrone (VSG) est l’une des solutions les plus populaires pouvant participer à l’augmentation de l’inertie des microgrids et pouvant être intégré dans les études de stabilité traditionnelles car il présente des similitudes avec une machine synchrone. Le VSG étant encore un concept récent, principalement pris en compte pour l'intégration de la DER dans un microgrid, diverses problématiques demeurent non résolues (certaines d'entre elles sont abordées dans ce manuscrit). De plus, les différentes solutions trouvées dans la littérature ne prennent pas en compte les aspects industriels et pratiques de son développement (également pris en compte dans cette thèse industrielle).Cette thèse est dédiée aux onduleurs basés sur le VSG et à leur intégration dans des microgrids à forte pénétration d'énergie renouvelable variable. Cette thèse a été réalisée grâce à la coopération de deux laboratoires, G2Elab et Gipsa-Lab, en collaboration avec Schneider Electric et son équipe de R & D, Power Conversion The classical distributed energy resources (DER) supplying energy to microgrids (usually diesel generator-sets) are progressively supplanted by supplier based on renewable energy sources (RES). However, the intermittency of RES leads to major stability issues, especially in the context of microgrids, notably because these sources usually decrease the available inertia of the grid. Hence, the traditional control strategies for inverters, interfacing the various DERs connected to the microgrid, needs adapting.The virtual synchronous generator (VSG) is one of the most popular solution that can participate in increasing the microgrids inertia and that could be integrated into traditional stability studies because it presents similarities with a synchronous machine. As the VSG is still a recent concept, mostly considered for the DER integration in microgrid, various problematics remain unresolved (some of which are addressed in this manuscript). In addition, the different solutions that can be found in the literature do not consider the industrial and practical aspect of its development (also considered in this industrial thesis).This thesis is dedicated to the VSG-based inverters and their integration in microgrids with a high level of variable renewable energy penetration. This PhD have been carried out thanks to the cooperation between two laboratories, G2Elab and Gipsa-Lab, in collaboration with Schneider Electric and its R&D team, Power Conversion

La grande distribution affiche une politique anti-gaspillage et a ainsi proposé dès 2014des Fruits et Légumes (F&Ls) « moches » [109] à la vente. Mais ces ventes sont temporaires et locales,et ont des effets peu étudiés sur le comportement des consommateurs. Nous proposons ici d'étudier si un magasin virtuel immersif (dans lequel nous contrôlons les F&Ls) peut être utilisé pour étudier le comportement des consommateurs confronté à des F&Ls « moches ». Afin d'avoir assez de F&Ls pour remplir le magasin virtuel, nous avons généré des F&Ls d'apparences variables de manière semi-procédurale comme suit :(1) nous générons le maillage avec des Cylindres Généralisés (CGs) [6] ; puis (2) gêneront les couleurs avec un système de particule.Nous avons réalisé 2 études comparatives (resp.N=142 et N=196). L'une portant sur le comportement consommateur lorsque les F&Ls sont plus ou moins anormaux (8F&Ls séparés en 4 groupes : sans déformation,légèrement déformés, déformés et fortement déformés). Ces différences n'avaient pas d'incidences sur le comportement. L'autre portait sur le comportement consommateur lorsque l'environnement est plus ou moins immersif (8 F&Ls sans déformation et 8 F&Ls déformés, séparés en 3groupes : magasin laboratoire, magasin virtuel non immersif et magasin virtuel immersif). Il existe des différences entre ces environnements sur le comportement. Enfin, nous avons étudié si la représentation virtuelle du consommateur avait un effet lors de l'achat des produits (incluant, mais ne se limitant pas aux F&Ls) nous avons donc réalisé une étude (N=29) avec 2 groupes : avatar obèse et avatar non-obèse. Il existe des différences localisées entre ces représentations sur le comportement consommateur The retail sector has an anti-waste policyand has therefore offered “ugly” FaVs (Fruits and Vegetables) for sale as early as 2014 [109]. But these sales remain temporary and local and have little studied effects on consumer behavior. We propose here to study if an immersive virtual store (in which we control the FaVs) can be used to study consumer behavior confronted to “ugly” FaVs To have enough “ugly” FaVs to fill the virtual store, we developed a method capable of generatings emiprocedural FaVs. To do so we: (1) generate the mesh with Generalized Cylinders (GCs) [6]; then (2) generate the colors with a particle system.We conducted 2 comparative studies (N=142 andN=196 respectively). The first study focused on consumer behavior when the FaVs are abnormal (8 FaVs separated into 4groups: no deformation, slightly deformed, deformed and strongly deformed). These differences had no impact on consumer behavior. The other study focused on consumer behavior when the environment is more or less immersive (8 FaVs without deformation and 8 FaVs with deformation, separated into 3 groups: laboratory store, non immersive virtual store and immersive virtual store).There are differences between these environments on consumer behavior. Finally, we studied if the virtual representation of the consumer had an impact during the purchase of products (including, but not limited to, FaVs). To do so we carried out a third consumer study (N=29) (2groups: obese avatar and non-obese avatar). There are very localized differences between these representations on consumer behavior
