Wind turbine performance enhancement by control of pitch angle using PID controller and particle swarm optimization

In this paper we present a new control strategy of wind turbine, by controlling the pitch angle that must be regulated to capture the maximum of power using PID controller and particle swarm optimization, the problem is to identify the PID controller parameters employing the PSO technique. This study makes a mathematical model, which is used to control the power characteristics of the turbine, a comparison with proposed strategy and genetic algorithm PID controller is performed. Simulation results show that the proposed approach results is better power regulation and less pitch action. The proposed strategy is easy to realize and has stronger robustness.
