Closed loop proportional resonant controller controlled DC microgrid system with advanced material technology in solar PV system

Abstract

Direct Current microgrid has emerged as one of the major research fields in recent years due to the higher level of benefits of the DC system when compared to the AC system, such as energy storage, flexibility with modernized loads, and renewable energy sources. Many studies have been conducted on the DC microgrid system in order to improve its efficiency. In this work, by using conventional PI controllers and advanced controllers like fractional order proportional integral derivative (FOPID) and proportional resonance (PR) controllers, a DC microgrid system is controlled. A closed-loop DC micro-grid containing sustainable power sources, stockpiled components, and transients is introduced. The PI controller is the most commonly used in power frameworks for assisting with the control of microgrids. Aside from PI, there are a slew of independent and hybrid regulators that can serve significantly better than PI in terms of microgrid framework relevance. The closed-loop DC microgrid framework systems with FOPID-FOPID and PR-PR-based DC microgrid structures are investigated and re-enacted utilising Simulink in MATLAB, and their outcomes are introduced. This paper also looks at advanced solar cell material technology, which has been used as an energy source in the DC microgrid system for higher power delivery. In this work, the performance of several solar cell types is compared along with an overview of recent developments in solar cell technology.
