Available in PDF, EPUB and Kindle. Book excerpt: Although Photovoltaic (PV) sources have been around for a long time, their contribution in power systems is limited due to factors related to their low efficiency and the complexity of their control. In this dissertation, efficient and effective control algorithms are developed for single phase microgrid-connected photovoltaic (MCPV) sources. The developed algorithms are divided into three levels based on their scopes. Level-1 includes algorithms that perform tasks within the MCPV control system. Level-2 coordinates the parts of the MCPV control system. Level-3 analyzes microgrids and the interactions among their sources. In level-1, algorithms are developed for phase-locked loop and harmonics estimation. The available algorithms for these tasks are computationally demanding and are sensitive to the disturbances that take place in microgrids. Efficient, accurate and robust algorithms are therefore developed in this dissertation for these tasks. The real power control of MCPV sources is covered in level-2. To operate effectively, the MCPV sources need to produce the maximum possible amount of power and to participate in regulating the voltage and frequency of the microgrid. The MCPV control system can be configured in different ways to achieve these tasks, however the performance of some of the configurations is unsatisfactory. A novel configuration for the MCPV controllers is proposed to perform the required tasks effectively without a need of supervisory controllers. Moreover, a procedure is developed to tune the controllers and ensure the stability of the MCPV sources. In level-3, an algorithm is developed to perform load flow analysis (LFA) for microgrids. The developed LFA is used in an optimization process that tunes the droop parameters such that the load is fairly distributed among the sources. The optimization problem takes into consideration the nature of the MCPV sources by adjusting their parameters adaptively such that their reactive powers increase when their production of real power decreases. The tasks in the three levels are combined in the MCPV control system. The developed algorithms are found to be effective through simulation studies and hardware experimentation. Using the developed controllers, the MCPV sources can provide many services to the power systems using low cost control systems.

Available in PDF, EPUB and Kindle. Book excerpt: Modeling of photovoltaic sources and their emulation by means of power electronic converters are challenging issues. The former is tied to the knowledge of the electrical behavior of the PV generator; the latter consists in its realization by a suitable power amplifier. This extensive introduction to the modeling of PV generators and their emulation by means of power electronic converters will aid in understanding and improving design and set up of new PV plants. The main benefit of reading Photovoltaic Sources is the ability to face the emulation of photovoltaic generators obtained by the design of a suitable equipment in which voltage and current are the same as in a real source. This is achieved according to the following steps: the source electrical behavior modeling, the power converter design, including its control, for the laboratory emulator. This approach allows the reader to cope with the creation of an indoor virtual photovoltaic plant, in which the environmental conditions can be imposed by the user, for testing real operation including maximum power point tracking, partial shading, control for the grid or load interfacing, etc. Photovoltaic Sources is intended to meet the demands of postgraduate level students, and should prove useful to professional engineers and researchers dealing with the problems associated with modeling and emulation of photovoltaic sources.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of DC microgrids is a promising concept that could improve power system reliability and stability in the future. The advantages of microgrids in general include an increase in energy efficiency through lowered energy transmission and operational costs, a reduced carbon footprint through the integration of renewable energy resources, and improvements in power quality and availability to end users through the use of advanced control techniques. DC microgrids have the potential to provide additional advantages, including decreasing interconnection conversion levels of distributed energy resources and energy storage systems, and preventing the propagation of power system disturbances. Power system research groups around the world are investigating the DC microgrid concept through simulation platforms and experimental setups. Several strategies have been proposed for the control of DC microgrids, including hierarchical, distributed, and intelligent control strategies. In this work, PSCAD/EMTDC simulation environment was used for the modeling and simulation of a DC microgrid. A power management strategy was then implemented in order to ensure voltage regulation and seamless transition between grid-connected and isolated modes. The strategy is based on an autonomous distributed control scheme in which the DC bus voltage level is used as an indicator of the power balance in the microgrid. The autonomous control strategy does not rely on communication links or a central controller, resulting in reduced costs and enhanced reliability. As part of the control strategy, an adaptive droop control technique is proposed for PV sources in order to maximize the utilization of power available from these sources while ensuring acceptable levels of system voltage regulation. These goals are achieved by avoiding the curtailment of renewable energy until violation of the voltage regulation limit occurs. The adaptive droop control then curtails the output power of the PV sources and, at the same time, restores the DC voltage level to within an acceptable tolerance range.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research program is to investigate promising techniques for enhancing the performance and robustness of grid-forming photovoltaic (PV) sources in microgrids and other distribution power system applications during large load disturbances and unbalanced operating conditions. Natural gas-powered generators are attractive candidates for backing up PV sources to enhance the power system's robustness as the PV penetration level increases. The technical challenges in this type of mixed-source system caused by PV dynamic overloading conditions include rapid drops in system frequency and PV dc bus voltage sags. PV power reserves represent a particularly promising solution to deal with these survivability challenges. Effective control strategies to implement and enhance power reserve capabilities have been proposed and confirmed using closed-form analysis, simulation, and experimental verification tests. Data-driven dynamic performance predictions and control development of two-stage grid-forming PV sources are also investigated as promising approaches for enhancing power reserve performance by improving the selection of the power reserve level and suppressing undesirable dc-link voltage dynamics, respectively. A new algorithm for model-based maximum power point (MPP) estimation that does not require additional atmospheric sensors is proposed that delivers more accurate MPP estimates with low computational complexity. Time-correlated relationships identified in changing atmospheric condition values have been harnessed to improve the estimation accuracy under harsh weather conditions. An undesirable dc bus voltage overshoot condition that can develop in lightly-loaded grid-forming PV sources has been characterized, and a minimum power limit control has been successfully applied to alleviate the adverse effects caused by the inverter diode freewheeling current paths. Abnormal operating conditions including grid faults, asymmetrical transmission line impedances, and uneven distribution of single-phase loads can appear in three-phase microgrids and distribution systems, causing adverse effects on grid-forming PV sources. The dynamic phasor model has been adopted to investigate the impact of network component values and source-related characteristics on system dynamic performance for varying voltage unbalance levels. Control techniques have been developed to alleviate the associated stress from power oscillations on the PV dc bus and improve the power quality by counteracting the effects of negative sequence voltage components caused by unbalanced operating conditions.

Available in PDF, EPUB and Kindle. Book excerpt: At present, photovoltaic (PV) systems are taking a leading role as a solar-based renewable energy source (RES) because of their unique advantages. This trend is being increased especially in grid-connected applications because of the many benefits of using RESs in distributed generation (DG) systems. This new scenario imposes the requirement for an effective evaluation tool of grid-connected PV systems so as to predict accurately their dynamic performance under different operating conditions in order to make a comprehensive decision on the feasibility of incorporating this technology into the electric utility grid. This implies not only to identify the characteristics curves of PV modules or arrays, but also the dynamic behaviour of the electronic power conditioning system (PCS) for connecting to the utility grid. To this aim, this chapter discusses the full detailed modelling and the control design of a three-phase grid-connected photovoltaic generator (PVG). The PV array model allows predicting with high precision the I-V and P-V curves of the PV panels/arrays. Moreover, the control scheme is presented with capabilities of simultaneously and independently regulating both active and reactive power exchange with the electric grid. The modelling and control of the three-phase grid-connected PVG are implemented in the MATLAB/Simulink environment and validated by experimental tests.

Available in PDF, EPUB and Kindle. Book excerpt: Energy independence depends greatly on the adoption of renewable energy sources. Yet, electricity, a commodity of everyday life, is currently being generated primarily from fossil fuels in the U.S. Despite the abundance of solar energy, the total electricity from photovoltaic (PV) sources is negligible, mainly because of the relatively high cost of PV systems. For PV electricity to become mainstream, its price has to reach grid parity, which is unachievable unless the overall cost of PV systems is reduced. Alternating-current (ac) PV modules are shown to have the potential to significantly decrease the cost of PV systems. An ac PV module consists of an individual conventional PV module embodying a small inverter, often called a microinverter. AC PV modules provide simpler, faster, and less expensive installation. Unlike typical inverters, microinverters are more reliable and robust and do not have to be replaced once or twice over the lifetime of the system. The flexibility provided by ac PV modules with individual maximum power point tracking (MPPT) may also increase the energy yield. With several microinverters operating simultaneously in a PV system, as opposed to only one or two bigger inverter(s), it is of particular interest to investigate the behavior and dynamics of such a PV system and its compliance with regulatory codes and standards when interconnected with the utility grid. For this purpose, complete detailed ac PV module models, along with different possible control techniques, are developed, analyzed, and tested through simulations. Average-value models (AVMs) for the ac PV modules are shown to drastically reduce simulation times while preserving their performances. The ac PV module AVMs therefore allow for rapid simulations and analyses of several ac PV modules running concurrently under numerous conditions.
