PID Type Stabilizer Design Using Grey Wolfe Optimization Algorithm

摘要

In this paper Grey Wolfe (GW) optimization algorithm is proposed for optimal tuning of PID based stabilizer. The time domain based objective function is considered for the robustly PID parameters tuning problem under a wide range of operating conditions. The optimization problem is solved by the GW Algorithm (GWA) which provides robust and desirable solutions. Results evaluation on a Single Machine connected to Infinite Bus (SMIB) confirm an excellent capability of the GWA based tuned PID to stabilize power system in comparison to the invasive weed optimization based PID controller for different operating conditions. Also, overshoot, undershoot, settling time and some system performance indices are calculated for two PID based stabilizers, and results prove that the proposed GWA method is better than IWA based PID stabilizer.
