An Optimal Control Strategy for Improving the Output Power of a Standalone Wind Energy System

Abstract

This research provides an optimal control technique for increasing a solitary wind energy system's output power. Because of the potential for strong winds, the use of renewable energy, particularly wind turbines, is becoming more popular in Indonesia. In general, the wind turbines deployed in Indonesia are small-scale, based on the existing wind potential. A permanent magnet synchronous generator (PMSG) type generator is best suited for this tiny scale wind turbine. Because it adapts the very unpredictable wind speed, the wind turbine system implements the off-grid system. This work used a method based on maximum power point tracking (MPPT) control to increase the performance of this wind turbine system. Converters connected to PMSG generators use an MPPT control-based control technique. The perturbing and observing (PO) algorithm support this MPPT control technique. A characteristic test on a 1000-watt wind power plant running at wind speeds ranging from 3 to 10 m/s is carried out in this study. Simulink- MA TLAB software is used to simulate this performance test. The results revealed that using MPPT control on wind turbine systems can greatly increase power output.
