STATCOM and PID Controller Based Stability Enhancement of a Grid Connected Wind Farm (original) (raw)

2019 International Conference on Energy and Power Engineering (ICEPE), 2019

Abstract

Wind energy are drawing utmost importance in the research arena day by day as one of the renewable energy sources due to the limitation in conventional energy resources. But to stabilize the voltage harvested from wind energy has become a point of major concern. Different methodology are being adopted to mitigate this. In this study, grid-connected wind farm stability has been upgraded by mitigating voltage fluctuation and attaining reactive power compensation using Static Synchronous Compensator (STATCOM). Voltage control loop with PID controller has been used to control STATCOM. A Pulse Width Modulation (PWM) method has been adopted as the control strategy of STATCOM. Different comparative study regarding stabilization of a wind farm has been performed using different approach (i.e. wind farm with capacitor bank and STATCOM or using STATCOM along with Proportional-integral-derivative (PID) controller) during wind speed change. Comparison of result shows that STATCOM with PID controller offers better performance with enhanced stability.
