Abstract

This paper discusses robust fuzzy sliding mode based UPFC controller for stability improvement in a standalone wind- diesel-fuel cell hybrid power system. Small signal model of the hybrid power system with UPFC controller has been modeled and state space equations of the system matrix is formulated for complete analysis. Performance of PI controller based UPFC has been analyzed in stability analysis and it is further improved with a fuzzy logic enhanced sliding mode controller. Variations of different parameters of the hybrid system are noticed for different wind power inputs and load variations. Results with conventional controller have been compared with Fuzzy sliding mode controller and Adaptive Fuzzy sliding mode controller. From the simulation results, the system performance is observed and vital information regarding voltage stability, damping of power oscillations and transient stability are collected.
