Variable Step Perturbation MPPT Method Based on Fuzzy Control for Wind Power Generation System

Abstract:

Traditional MPPT control strategy by hill climbing searching for wind power generation system (WPGS) dependent on wind turbines parameters, the oscillation around maximum power point (MPP) was serious. A new variable step perturbation MPPT was presented based on fuzzy control, the variable perturb step was determined with the power characteristic curves point slope, the control system was described with fuzzy language for maximum power capture, the principle of MPPT was analyzed and the variable step method was adopted with fuzzy control, the simulation result shows that this advanced control strategy could improve tracking speed, enhance the stability and the oscillation around maximum power point reduced.
