DE-Assisted LFC of Three-Area Six-Source Interconnected Power System with Wind Model and Fuel Cell Under Restructured Environment

摘要

The area frequency control named as load frequency control (LFC) of three-area six-machine power system with asynchronous power transfer links in the presence of the combination of wind generating system and fuel cell is studied in this paper. Instead of concentrated conventional environment, deregulated environment with different scenarios is presented in this work. The test system influences the frequency in the presence of the combination of wind and fuel cell under constant load conditions leads the frequency oscillations. The overall system performance is improved in the presence of asynchronous tie-lines along with sudden load disturbances with proportional-integral-derivative controller as secondary controller. The secondary controller parameters are optimized using differential evaluation technique. The observations from results show that the powerful differential evaluation technique validates with renewable energy sources under open market system. The peak values and settling time are reduced with the insertion of both AC and DC links. The simulations are done in MATLAB/Simulink environment.
