STATCOM based fuzzy logic damping controller for improving dynamic stability of a grid connected wind power system

Abstract

In this paper, a Fuzzy Logic Damping Controller (FLDC) is applied to control a Static Synchronous Compensator (STATCOM) to improve the stability of a grid connected wind power system. The wind power system is represented as a Doubly Fed Induction Generator (DFIG) driven by a wind turbine. The power grid is simulated by a standard IEEE 14-bus power system. Basically this studied system has 14 buses, 5 generators and 11 loads. The studied 6-MW wind power system includes 3×2-MW wind generator connected to Bus 14 of the studied system. Simulation results are performed with different disturbance conditions for testing the stability of the studied system. It can be concluded from simulation results that the designed FLDC for the proposed STATCOM helps to improve the stability of the studied system.
