Enhanced Proportional Resonant – Second-Order General Integrators (EPR-SOGI) With Fuzzy Logic Control in Hybrid Renewable Energy Source-Based STATCOM

Abstract

In this paper, the fuzzy-logic controllers (FLC)-based enhanced proportional resonant – second-order general integrators (SOGI) method for Static Compensator is provided to improve the quality of power. The Hybrid Renewable Energy Sources provide support for the quasi-Z- source inverters (qZSI) that is known as HRES-STATCOM. In the usual approach, the actual dc-link voltages of the inverters are controlled by the PI controllers using a fixed reference DC-link voltage, which may result in excessive switching loss and switching noise. As system or load characteristics vary in real-world applications, a low DC-link voltage may be required, resulting in less switching losses and noise. As a result, an FLC-based EPR-SOGI method has been suggested. This approach gives the optimal reference DC-link voltage, which reduces the switching losses and hence offers improved compensation in varying-parameter settings as well. In the framework of Matlab/Simulink, the EPR-SOGI algorithm is designed and then simulated for three distinct cases. According to the findings of the research, it is abundantly clear that the suggested algorithm is better than the conventional algorithm in terms of its adaptability and its robustness. A laboratory-developed experimental setup is also used to verify the superiority of the suggested algorithm over the traditional method.
