Abstract
En 中文
This study presents a hybrid energy storage power converter solution for island microgrids, integrating photovoltaic (PV) systems, energy storage batteries, and diesel generators to ensure a stable power supply. The system design considers the variability and uncertainty of renewable energy sources. When weather changes affect PV or energy storage systems, the diesel generator can quickly start as a backup power source, maintaining stable electricity to the load. Experimental validation was conducted through load switching tests (6 kW to 32 kW), diesel generator integration scenarios, and battery charge/discharge verification using a 100 kW power conversion system with 100 kWh energy storage capacity. Results show that the system effectively integrates renewable energy, enhances power supply reliability, and maintains high efficiency under various operational conditions with response times under 50 ms, voltage stability within +/- 2%, and frequency deviation below 0.1 Hz. These findings provide both a theoretical basis for island microgrid applications and valuable reference for future design and implementation of stable microgrid systems, with significant implications for improving energy autonomy and sustainable development in island regions.
