Power Quality Enhancements of AC Grid Using Luo Converter with GWO Based MPPT

Abstract

The Hybrid Renewable Energy System (HRES), which consists of multiple solar panels and wind turbines along with energy storage device, has been used in this work to satisfy the requirements of power consumers. Because of its multiple benefits like cheap maintenance, economic benefits, and fuel independence, photovoltaic power generation has gotten a lot of attention in recent decades. However, getting stable and enhanced power from the PV is the most difficult task and so the highly efficient LUO converter is developed in this work which generates a stable output voltage from an unregulated dc source. In order to optimize the performance of LUO converter and to get supreme power output, GWO based MPPT algorithm is used since it is the most adaptive methodology that is not dependent on system information. On the other hand, Wind Energy Conversion System (WECS) contribution to global energy supply has been steadily increasing. To enhance the wind power generation, a DFIG is utilized, also a PI controller has been assigned which controls the power delivered to the inverter through the PWM rectifier. Grid synchronization is achieved by employing a PI controller which analogize the real and reactive power and delivers it output to the 3ϕ inverter through the PWM generator. MATLAB/Simulink is used to simulate the overall system in this work.
