Comparative performance of wind turbine driven PMSG with PI-controllers tuned using heuristic optimization algorithms

An efficient methodology for the tuning of proportional-integral controllers´ gains for the generator-side converter of a wind turbine driven permanent magnet synchronous generator using a self-adaptive global best harmony search algorithm is proposed. Performance of the generator with the optimized controller parameters obtained using the proposed algorithm is compared with the parameters obtained using the Ziegler-Nichols technique, bees colony, and simulated annealing algorithms. Studies demonstrate that the performance of the system with the optimized controller parameters permits an improvement of the converter capability.
