Mitigation of Power Quality Issues in Hybrid Solar-Wind Energy System using Distributed Power Flow Controller

Abstract

Renewable Energy Sources find a scope for the prospects in meeting the growing demand with high power quality and reliability. This has led to the concept of Microgrid with widespread power supplying generation units called distribution generation units. The operation of a Micro-grid can be autonomous or with public grid interconnection. The combination of solar power and wind power is a reliable source of energy creating a constant energy flow by avoiding the fluctuations. The increase in penetration of non-linear loads and power-electronic incorporated distribution generation system initiates power quality disputes in the distributed power system. Hence, the mitigation of power quality issues is more fixated and few investigations led to the use of FACTS devices such as custom power semiconductor devices for this purpose. Distributed Power Flow Controller, which is emerged from Unified Power Flow Controller, is considered as the most reliable device among all the devices. The main difference between these devices is the absence of DC-link in Distributed Power Flow Controller. This paper presents the enactment of Solar-wind hybrid system without custom power device and with Distributed Power Flow Controller. The simulation results are validated using MATLAB/SIMULINK software.
