Automatic Generation Control of Micro Grid Interconnected Power System Using GWO

Abstract: In this paper, a micro grid (MG) power generation system is interconnected with a single area reheat thermal power system for load frequency control study. A new heuristic optimization algorithm Grey wolf Optimization (GWO) algorithm is applied to evaluate optimal gains of the proportional integral and derivative (PID) controllers. The system dynamic performance is studied by comparing the results with GWO optimized PI/PID controllers. Also the system performance is investigated with PID controller optimized by recently developed grey wolf optimizer (GWO) algorithm, which has proven its superiority over other previously developed algorithm in many interconnected power systems.

Keywords: Micro grid, Load frequency control, Grey wolf optimization algorithm, PI/PID controllers.
