Fuzzy sliding mode-based STATCOM for stability and reactive power compensation in DG-based power system

Abstract

The objective of the paper is to study the reactive power regulation and stability study of an isolated wind-fuel cell hybrid power system. A Fuzzy sliding mode-based STATCOM controller has been considered for compensating reactive energy in a wind-diesel-fuel cell-based remote hybrid power system. For detailed analysis and simulation, a transfer function small signal model of the hybrid power system has been considered. A double-fed induction generator-based wind turbine and fuel cell are the main constituents of hybrid system with a diesel generator as backup. The system performance is studied with a random variation of loads and wind power input. Further the system performance is improved and analyzed with the incorporation of Fuzzy sliding mode-based STATCOM controller.
