PI controller parameters design of doubly fed induction generator based on Mine Blast Algorithm

Abstract

In this paper, a control strategy optimized by Mine Blast Algorithm (MBA) is applied on a variable speed wind generator (VSWG) system based on a doubly fed induction machine. The proposed MBA is applied to evaluate the optimal parameters of the current PI controller such that obtaining rotor current closes to the desired one; this purpose is achieved by minimizing the sum of squared error (SSE) between two currents. A direct closed loop control of stator current is taken place to regulate the reactive power of DFIG. The obtained results confirmed the efficiency of the proposed algorithm for determining the optimal gains of PI controller.
