Grey Wolf Optimized Pi Controller for High Gain SEPIC Converter for PV Application

A high gain SEPIC converter for PV applications, as well as a Grey Wolf Optimized PI controller are used in this modules. As there are frequent variations in climatic conditions, solar irradiation is not constant for every time. Hence for boosting the output of the PV system, it employs a DC-DC SEPIC converter are used. A GWO optimized PI controller based on the closed loop approach is used to maintain constant DC link voltages at the converter's output. The improved PV system efficiency is achieved with the application of GWO and further, the voltage of the DC link reached the load. With the defined work, high gains and switching losses are attained. In this modules is implemented by MATLAB simulation.
