I n this paper, a PID controller designed for frequency stabilizing in an isolated wind-diesel power system and tuning of PID controller gains, formulated as an optimization problem and solved using Interior Search Algorithm (ISA). In order to prove the performance of proposed method, four cases of simulations are assumed, step change in load of diesel side, step change in wind speed, random changing of the diesel side load and random changing of the wind speed. Also, performance indices like overshoot, undershoot, settling time, ITAE and ISTSE are calculated and compared with Bee Colony (BC) algorithm. Results show that the proposed method is very robust and effective.
