Simulation Model of Voltage Balancing Circuit Among Supercapacitors in Photovoltaic Microgrids

This paper focuses on the simulation model research of voltage balancing circuits among supercapacitors in photovoltaic microgrids. To ensure stable voltage output in microgrid systems, detailed investigation of voltage balancing circuits between supercapacitors is essential. The study begins by introducing fundamental concepts of photovoltaic microgrids, followed by an in-depth exploration of supercapacitor characteristics and their functional roles. Subsequently, we elaborate on the operational principles of voltage balancing circuits connecting supercapacitors and establish a comprehensive simulation model. The implementation involves algorithmic approaches for voltage equalization using passive/active balancing techniques, with simulation code typically modeling capacitor dynamics and control logic. Finally, through analysis of simulation results, we evaluate the performance of the balancing circuit, providing valuable references and guidance for the design and optimization of photovoltaic microgrid systems. Key simulation aspects include state-of-charge balancing algorithms and voltage regulation mechanisms implemented through control loops.
