Modes in stable operation of energy storage include modes 13, 14, 15, 16, 18, 20 and 22. Taking mode 13 as an example, the power coordinated distribution method of ES in the critical over-discharge operation is verified.
Although some energy storage power stations are in the overcharge range in modes 2, 5 and 6, the system requires energy storage discharging. So it does not need to be modified, and it can be dynamically distributed based on the chargeable/dischargeable amount of ES.
The energy storage power station is dynamically distributed according to the chargeable/dischargeable capacity, the critical over-charging ES 1# reversely discharges 0.1 MW, and the ES 2# multi-absorption power is 1.1 MW. The system has rich power of 0.7MW in 1.5–2.5 s.
The remaining modes 4, 7, 8, 9, 10, 11 and 12 are the same as the mode 3 energy storage power distribution. At this point, the energy storage SOC using the V/f control strategy is in the critical over-discharge range.
Critical range: SOC is in the critical over-chargeable/over-dischargeable range (S min ≤SOC t ≤S min_stable, S max_stable ≤ SOC t ≤ S max). At this time, the critical operation of the energy storage power station should be controlled to make it return to the normal range.
In this paper, the SOC variation range of stable operating energy storage is set as [0.3, 0.7], the critical overcharge interval is [0.7, 0.9], the critical overcharge interval is [0.1, 0.3], the pre-stop overcharge interval is [0.9, 1], and the pre-stop overcharge interval is [0, 0.1].
