Distribution System Voltage Regulation with Distributed Generation Based on VQC and SVC

Abstract:

The distributed generation (DG) may lead to a great impact on the reactive power flow, feeder voltage profile and the means of voltage regulation when integrated into a typical distribution system. Therefore, there is possibility that the customers voltage violate the permissible limits. In order to regulate the voltage of the distribution system with DG, local voltage and reactive power control (VQC) based on fuzzy control theory is adopted in substation and the Static Var Compensator (SVC) is installed in the appropriate node in this paper, and the fuzzy controller of VQC has been designed at the same time. A simplified model of a real 10kV radial distribution system has been simulated in MATLAB to illustrate the use of the voltage regulation method, and the simulation results show that the proposed method can regulate the line voltage of distribution system with DG within the regulated voltage ranges.
