Robust Control Techniques for Four-Area System with DFIG System

Distributed power generation based on solar power, wind energy will give critical energy in future. There has been an important progress in grid Technology to use the local energy sources and furthermore to reduce the transmission losses and increase the power sharing capability. This work considers the effect of disturbance and fault in four area system connected to DFIG. The controlling of four area system connected to DFIG is performed. The different PSSs are utilized in primary control action. The comparison in time domain response having without any controller mean without PSS, with simple or conventional PSSs (Delta Omega (ω) and Delta Pa (acceleration power)), MB (Multi-Band) PSS and Fuzzy Logic (FL) based PSSs. Using a test DFIG model, the performance of fuzzy controller (FL) power system stability is accessed via time domain simulation of the test DFIG model on MATLAB/Simulink (R2015a) environment.
