AI Technical Summary
When existing energy storage devices are connected to the main power grid, they cannot actively provide additional power support during system disturbances, resulting in the need to improve grid stability and power quality.
By obtaining the reference frequency, its change amount, and its rate of change of the inverter output, various compensation values are calculated to adaptively adjust the output power of the energy storage system. The voltage source method is used to support the power grid, avoiding the accuracy impact of the phase-locked loop structure, and achieving autonomous power compensation.
It improves the power output characteristics of the energy storage system under grid disturbances, enhances the power supply quality and stability of the grid, and provides more effective active support functions.
