Gravitational search algorithm based optimal pitch controller design for an isolated wind-diesel hybrid power system

In this paper, Gravitational Search Algorithm based optimal pitch controller design is proposed for an isolated wind-diesel hybrid power system. The Gravitational search algorithm (GSA) is one of the newest meta-heuristic searching algorithms, which is motivated by the Newton’s law of gravity and law of motion. The optimal controller parameters are obtained using Integral Square Error (ISE) criterion.  Simulation results show that the proposed Controller gives a superior dynamic performance and damps out the frequency deviation and attains the steady state value with less settling time.
