Abstract

The global community is actively investigating strategies to harness renewable energy power sources (REPS) in order to tackle the problem of global warming and reduce reliance on fossil fuels. Wind and solar energies are among the most plentiful and easily accessible forms of renewable energy available on Earth. Utilizing these sources for electrical power generation can prove to be an effective solution in meeting the energy demands of various regions. Photovoltaics (PVs) and Permanent Magnet Synchronous Generator (PMSG) coupled wind power conversion units are commonly installed for medium power applications. By integrating these two sources, a reliable and flexible power supply can be ensured for consumers at all times. Additionally, the incorporation of an energy storage device, such as batteries, is essential for maintaining energy management in standalone power supply units. As a result, a hybrid wind, battery and PV based microgrid has been developed, along with a novel control technique to ensure power quality at the load point. Traditional controllers like the Proportional-Integral (PI) controller may not perform optimally during rapid system changes due to their fixed gains. Therefore, a novel TS-Fuzzy controller-based control scheme has been implemented in this system. To optimize the utilization of REPS, the system has been equipped with devices that ensure maximum power point integration. The energy management system is facilitated by connecting the battery bank to the system through a DC to DC bidirectional circuit. The results of various case studies have been presented using the MATLAB software in this study.
