Aiming at the problem that wind power and energy storage systems with decentralized and independent control cannot guarantee the stable operation of the black-start and making the best of power relaxation of ESSs, a coordinated control strategy of multi-energy storage supporting black-start based on dynamic power distribution is proposed.
According to the above literature, most of the existing control strategy of energy storage power stations adopt to improve the droop control strategy, which has a great influence on the system stability and cannot be controlled again in case of blackout.
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.
Aiming at the over-charge/discharge, an adaptive multi-energy storage coordinated optimization method is proposed. The power allocation is based on the chargeable/dischargeable capacity and limit power. A black-start model of multiple wind power and energy storage system model is established.
Modes in stable operation of energy storage include mode 1, 2, 5, 6, 17, 19, 21, 23 and 24. Taking mode 1 as an example, the power coordinated distribution method of ES in the stable operation is verified. T = 0–1.5 s. The wind storage system is self-starting.
Establishment of bus voltage and frequency When the wind power and energy storage system receives the instruction to cooperate with the black-start of the power grid, the self-starting of the ESSs is to establish the stable voltage and frequency.
