Compared with the traditional control strategy, the proposed control strategy can effectively balance the SOH and SOC of each energy storage unit and keeps the system's overall capacity for a longer period.
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.
If the system is operated according to the traditional equal sharing control strategy, the simulation results are shown in Fig. 7 d, where the energy storage system has storage units whose health state drops to 80% after 3556 h of operation, which in turn reduces the capacity of the whole system.
Due to the disordered charging/discharging of energy storage in the wind power and energy storage systems with decentralized and independent control, sectional energy storage power stations overcharge/over-discharge and the system power is unbalanced, which leads to the failure of black-start.
The energy storage power station is dynamically distributed according to the chargeable/dischargeable capacity, the critical over-discharging ES 2# reversely charges 0.05MW, and the ES 1# multi-absorption power is 0.25 MW. The system has power deficiency of 0.5 MW in 1.5–2.5 s.
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.
