A “MPPT/power limitation” optimization strategy to Extend Optimal Energy Management in Hybrid Wind Turbine

Now a days research focus is towards the variable speed power generation in instead fixed speed power generation in wind energy conversion system (WECS). This paper proposes a new algorithm of maximum power point tracking (MPPT) supported by a power limitation controller. This system based on a variable structure” Automatic Systems approach. Moreover, the proposed algorithm is added to an advanced control and management system applied to hybrid wind turbines (WT) with permanent magnet synchronous generator (PMSG) to strengthen the extraction capacity of wind power and expands wind turbines (WTs) operating areas. The results have showed that the proposed control system (MPPT /power limitation control) is very effective compared to conventional methods and can maintain adequate performance on the entire operating range.
