【 摘 要 】

Aiming at the high-efficiency charging application requirements of solar photovoltaic (PV) energy storage systems, a novel control system architecture for solar photovoltaic energy storage applications is presented. The system dynamically adjusts its working state according to the real-time power generation data of solar photovoltaic output, thus realizing the hierarchically combined operating mode and operation state changes when applying different Environmental parameters. In addition, the corresponding algorithm was proposed to achieve efficient control. Compared with the conventional control system architecture, the developed circuits can realize high-efficiency solar charging and multi-mode flexible applications. An experimental prototype is implemented and the test results are derived to verify the effectiveness and superiority of the proposed system, which provides the new ideas and references for the application of photovoltaic energy storage systems.
