Voltage control of fuel cell-wind-diesel hybrid power system using FA based SVC and AVR controller

Abstract

This paper presents the voltage control of an isolated Fuel Cell (FC) wind diesel hybrid power system by coordinated control of static Var Compensator (sVC) and Automatic Voltage Regulator (AVR). The SVC and AvR are equipped with of Proportional and integral (Pi) controller, the parameters of which are optimized simultaneously using Firefly Algorithm (FA) under certain disturbance conditions. The dynamic response of the system has been tested variable load disturbances plus variable nature of the wind power.
