Design of Wind Turbine Battery Charging Control a Buck-Boost Converter with PID Control Optimized by Ant Colony Optimization

This research proposes a voltage control strategy for battery voltage in wind turbine battery charging systems. Changes in wind speed in wind turbine systems can cause the generated voltage to be non-optimal, which in turn can affect the life of the battery. A buck-boost DC-DC converter can be used to regulate the battery charging mode. This converter is controlled by PID to keep the battery voltage constant. In this study, the PID parameters are optimized using Ant Colony Optimization (ACO) to achieve optimal control. This study will use a comparison of 2 methods, viz: System using PID tuning control method and system controlled by PID with Ant Colony Optimization. The results obtained in this study are the battery voltage generated by the PID tuning system of 51.87 V and the battery voltage generated by the ACO system of 51.95 V. While the battery SOC generated by the tuning system is 50.02 and the SOC generated by the ACO system is 50.12, The time required for the tuning system is 0.53 and the time required for the ACO system is 0.42. It can be seen that the ACO system is better and more efficient than the tuning system. This research was designed using MATLAB/Simulink.
