Artificial immune system based design of current controlled voltage source converter for PM wind generator

In this paper a novel design method of current controlled voltage source converter for variable speed permanent magnet wind generator is proposed. The method is based on optimum tuning process of PI gain parameters of voltage source converter control system with the artificial immune system (AIS) algorithm considered. The analytical simulation studies have been performed using MFILE/MATLAB. In order to verify the effectiveness of the proposed method, the simulation studies using PSCAD/EMTDC have also been performed. Simulation results show that the proposed method is very effective in enhancing the dynamic stability of the wind generator system.
