PMSG based WECS with MPPT via modified P & O algorithm

Gearless wind energy conversion system based supplies can be a long term solution in case of distributed generation. This paper validates a modified control algorithm for maximum power point tracking of Permanent magnet synchronous generator (PMSG) based wind energy conversion system. This work aims to optimize the losses by extracting maximum wind energy. Permanent Magnet Synchronous Generator is used as it provides gear free mechanism, low noise and it's easy to control. DC-DC boost converter has been used for implementing MPPT by controlling the duty ratio. This ensures effective utilization of wind energy. In this work the instantaneous values of input side current and voltage are used for implementing MPPT. Modified (P&O) algorithm is used which is more efficient as compared to its traditional counterpart. It reduces the problem of unsettlement around the peak point. The whole work is verified in MATLAB/ Simulink environment by carrying out simulation for the proposed work.
