Currently, there are two primary switching strategies for bidirectional energy storage converters: one is the switching strategy combining PQ control and V/f control, and the other is the switching strategy based on droop control [3, 4, 5, 6].
Grid-connected control strategy of energy storage system based on additional frequency control. 1. Existing flat/smooth control strategy. The power of the PV station is taken as the input signal. The output power of the ESS is generated to suppress the fluctuation of the PV/ESS station according to different time scales.
Due to the disruptive impacts arising during the transition between grid-connected and islanded modes in bidirectional energy storage inverters, this paper proposes a smooth switching strategy based on droop control to mitigate such impacts.
Here, both inverters are set to an active power reference of 30 kW and a reactive power reference of 5 kVAR. Note that the initial battery charge levels are set to 80% for the first and 50% for the second battery to allow evaluation of the inverter's capability to disconnect a battery as it approaches its lower SoC limit.
Step changes in the inverter's reference power show the strategy's quick adaptation to reactive power demands, while maintaining a stable active power supply. Furthermore, active power control disconnects the BESS when it approaches its lower SoC limit in a near-depleted battery scenario.
