Performance analysis of maximum power point tracking control system for standalone wind power system in Sittwe, Myanmar

Abstract

One of the most feasible Renewable Energy resources of the World is wind energy. The performance of the Maximum Power Point Tracking (MPPT) control system for the operation of the Standalone Wind Power generation system is studied in this research. Sittwe, the capital of Rakhine State in Western Coastal Region, is the chosen case study area that enriches the Wind Energy resources in Myanmar with the low electrification rate. The proposed Standalone Wind Power generation system is composed of three-phase, 20kW Permanent Magnet Synchronous Generator (PMSG), DC-DC bidirectional converter, switch mode rectifier, voltage source inverter, and three-phase load. It is modelled and simulated in the MATLAB/Simulink. The simulation period is set to 15 seconds. Under Wind speed variation from 3 m/s to 13 m/s, the investigation is performed with the nexus of the speed, torque, power, DC link input, DC link output, and the parameters of the load side. In the simulation results, the power characteristics show the 20 kW standalone wind power system. It is observed that the output load voltage can be controlled by load side converter to required load voltage. In addition, the simulation results reflect the dynamic performance can be improved with the proposed MPPT control system.
