Control strategies of a microgrid which includes both synchronous generators and converter-based distribution generation (DG) units must be designed such that effective operation of the microgrid is achieved. The main objective of this paper is to develop a high performance control strategy for an islanded medium voltage (MV) microgrid consisting of inverter and non-inverter interfaced DG units. A...
Microgrids (MGs) and Distributed Generation are becoming a significant area of research because of their peculiar distinctiveness. Microgrids are composed of generating sources which can be renewable, placed near the customer side. Also, they have the intrinsic property of islanding i.e. the disconnection of either the MG from the main grid or a part of the MG from the rest of the MG. In this paper,...
Because of the increasing share of distributed generation (DG) units, a coordinated approach for their integration in the electrical network is required. Therefore, the microgrid concept has been introduced. Most DG units use power-electronic interfaces, i.e., converters, for which control strategies have been developed such that these units can participate in the microgrid control. Because of the...
This paper investigates dynamic behavior of a distribution subsystem (microgrid) with three distributed generation (DG) units to planned and accidental switching event. Three DG units are one gas-turbine synchronous generator and a variable-speed wind turbine with doubly fed induction generator (DFIG) and a converter based DG. A power control approach is proposed for DG units to provide both voltage...
