ENHANCEMENT OF POWERQUALITY IN WIND GRID ENERGY SYSTEM USING SHUNT FACTS DEVICE DRIVEN WITH BESS-CONTROL SCHEME

Abstract

The renewable energy resources like wind, solar, hydro, biomass etc. are required for sustainable growth and social progress, it is essential to meet the energy need by utilizing the renewable energy resources. The necessity of integrated renewable energy like wind energy in to the power system is to make it possible to minimize the environmental impacts. This project proposes the STATCOM control scheme for grid connected wind energy system for power quality enhancement. A bang-bang controller which his based on hysteresis current control scheme is developed for STATCOM. STATCOM is connected at a point of common coupling (PCC) to mitigate the power quality problems. The STATCOM control scheme applied for the grid connected wind energy generation system (WEGS) used for enhancement of power quality is simulated using MATLAB/SIMULINK in power system block set. This proposed scheme assures the enhancement of power quality in a generated output.
