Microgrid Energy Storage System Single Debugging Report

This report details the single debugging of a microgrid energy storage system, covering charge and discharge experiments, black start, planned off-grid, off-grid operation, frequency modulation, and voltage regulation tests. The charge and discharge experiments verify PCS performance under various power settings, SOC-based power allocation, and power limits. Black start tests confirm the system's self-power capability and parallel VF mode operation. Planned off-grid experiments demonstrate seamless voltage switching. Off-grid operation tests validate stable voltage and frequency under load. Frequency and voltage modulation experiments confirm correct wiring and pulse step sizes. All experiments were conducted under specified conditions, with data recorded for each test. The conclusions indicate that the PCS operates normally within design ranges, the centralized control system effectively balances SOC values, and the system can maintain stability during grid disturbances. The report provides essential validation for the energy storage system's reliability and performance in microgrid applications.
