TL;DR: In this article, the authors give a description of state of the art for distributed power generation systems (DPGS) based on renewable energy and explore the power converters connected in parallel to the grid which are distinguished by their contribution to the formation of the grid voltage and frequency and are accordingly classified in three classes.
Abstract: The introduction of microgrids in distribution networks based on power electronics facilitates the use of renewable energy resources, distributed generation (DG) and storage systems while improving the quality of electric power and reducing losses thus increasing the performance and reliability of the electrical system. The hierarchical control structure, which consists of primary, secondary, and tertiary levels for microgrids that mimic the behavior of the mains grid, is reviewed. The main objective of this article is to give a description of state of the art for distributed power generation systems (DPGS) based on renewable energy and explore the power converters connected in parallel to the grid which are distinguished by their contribution to the formation of the grid voltage and frequency and are accordingly classified in three classes. This analysis is extended focusing mainly on the three classes of configurations: grid-forming, grid-feeding, and grid-supporting. The article ends up with an overview and a discussion of the control structures and strategies to control distribution power generation system (DPGS) units connected to the network.

TL;DR: In this article, a droop control strategy is presented for accurate power sharing between parallel connected inverters in an AC microgrid in autonomous mode, which allows for maintaining voltage and frequency stability and regulating the power flows between the primary energy sources and the common AC bus.
Abstract: In this paper, a droop control strategy is presented for accurate power sharing between parallel connected inverters in an AC microgrid in autonomous mode. The proposed strategy is based on the droop control techniques P-f/Q-V and P-V/Q-f, with a virtual impedance and using monitored quantities directly at the inverter. This droop control approach can be used in microgrids where communications are not reliable or not available. It allows for maintaining voltage and frequency stability and for regulating the power flows between the primary energy sources and the common AC bus. The design methodology of the control scheme under study is based on grid-supporting-grid-forming controls using multi-loop dq control. The time domain simulation is conducted, in the MATLAB®/SimPowerSystems environment and the RT-EVENTS toolbox from OPAL-RT is also used to model the inverters. Resulting waveforms show that the proposed method can allocate both real and reactive powers effectively and can enhance the stability of a micro-grid in the autonomous operation mode.

TL;DR: This paper explores the control of shunt active power filters based on: 1) instantaneous power control strategy (p-q Theory) for extracting the reference currents for APF, and 2) adaptive hysteresis current control (AHCC) strategy for performance evaluation.
Abstract: In power grids, the active power filter (APF) is an important device for compensation of harmonic pollution and reactive power caused by nonlinear loads However, the control method has a significant influence on the APF performance in eliminating the distorted currents Henceforth, this paper explores the control of shunt active power filters based on: 1) instantaneous power control strategy (p-q Theory) for extracting the reference currents for APF, and 2) adaptive hysteresis current control (AHCC) strategy for performance evaluation Different case studies are carried out such as, balanced/unbalanced source with balanced/unbalanced load, distorted source with balanced load in Matlab®/ SimPowerSystems Simulation results highlight the effectiveness of the proposed control method

TL;DR: An attempt has been made to review the applications of fuzzy logic based models in renewable energy systems namely solar, wind, bio-energy, micro-grid and hybrid applications and indicates that fuzzy based models provide realistic estimates.
Abstract: In recent years, with the advent of globalization, the world is witnessing a steep rise in its energy consumption. The world is transforming itself into an industrial and knowledge society from an agricultural one which in turn makes the growth, energy intensive resulting in emissions. Energy modeling and energy planning is vital for the future economic prosperity and environmental security. Soft computing techniques such as fuzzy logic, neural networks, genetic algorithms are being adopted in energy modeling to precisely map the energy systems. In this paper, an attempt has been made to review the applications of fuzzy logic based models in renewable energy systems namely solar, wind, bio-energy, micro-grid and hybrid applications. It is found that fuzzy based models are extensively used in recent years for site assessment, for installing of photovoltaic/wind farms, power point tracking in solar photovoltaic/wind, optimization among conflicting criteria. The review indicates that fuzzy based models provide realistic estimates.

TL;DR: In this paper, the scheduling problem of DERs is studied from various aspects such as modeling techniques, solving methods, reliability, emission, uncertainty, stability, demand response (DR), and multi-objective standpoint in the microgrid and VPP frameworks.
Abstract: Due to different viewpoints, procedures, limitations, and objectives, the scheduling problem of distributed energy resources (DERs) is a very important issue in power systems. This problem can be solved by considering different frameworks. Microgrids and Virtual Power Plants (VPPs) are two famous and suitable concepts by which this problem is solved within their frameworks. Each of these two solutions has its own special significance and may be employed for different purposes. Therefore, it is necessary to assess and review papers and literature in this field. In this paper, the scheduling problem of DERs is studied from various aspects such as modeling techniques, solving methods, reliability, emission, uncertainty, stability, demand response (DR), and multi-objective standpoint in the microgrid and VPP frameworks. This review enables researchers with different points of view to look for possible applications in the area of microgrid and VPP scheduling.

TL;DR: An analytical technique using the `Newton-Raphson' method is presented to identify the saturated magnetising reactance and the generated frequency of a self-excited induction generator for a given capacitance, speed and load.
Abstract: An analytical technique using the `Newton-Raphson' method is presented to identify the saturated magnetising reactance and the generated frequency of a self-excited induction generator for a given capacitance, speed and load. The technique is shown to be very efficient in analysing such systems under steady state. Computed results are compared with the experimentally obtained values on a laboratory machine, and a reasonable correlation has been observed. Effects of various system parameters on the steady-state performance have been studied, and the results presented provide guidelines for optimum design of such systems.

TL;DR: In this paper, the most interesting topologies of hybrid ac/dc microgrids based on the interconnection of the ac and dc networks and the conventional power network are discussed.
Abstract: Microgrids have been widely studied in the literature as a possible approach for the integration of distributed energy sources with energy storage systems in the electric network. Until now the most used configuration has been the ac microgrid, but dc-based microgrids are gaining interest due to the advantages they provide over their counterpart (no reactive power, no synchronization, increasing number of dc devices, etc.). Therefore, hybrid ac/dc microgrids are raising as an optimal approach as they combine the main advantages of ac and dc microgrids. This paper reviews the most interesting topologies of hybrid ac/dc microgrids based on the interconnection of the ac and dc networks and the conventional power network. After performing a description and analysis of each configuration, a comparative evaluation has been performed to highlight the most important features of each one. The future trends identified during the study also show that several features such as the scalability, modeling or design require further research towards the integration of hybrid microgrids in the power network.
