A simple Human Simulating Intelligent PID for wind turbine Control under wind speed variation

Abstract

The biggest disadvantage of direct current vector is that the PI control is a linear regulator which is suitable just for linear time invariant systems. However, wind turbines components work as nonlinear systems where electromechanical parameters change frequently [3]. DFIG WT is an attractive solution in variable wind turbines [1, 2] because of its advantages like reduces losses, minimum cost, an improved efficiency and power control capabilities [2]. Inspired by the PID simplicity, a Human Simulating Intelligent PID is suggest to contribute with some important features like simplicity, flexibility, self-learning and heftiness ,ameliorate respond time, dealing with grid requirements. The variable speed wind energy generation system is validated in the Matlab/Simulink environment and the simulation results obtained confirm the effectiveness of the HIS-PID.
