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.
However, the ESUs are mostly integrated in distributed PV power plants in the previous research. Actually, if integrated energy storage station (BESS) is adopted by the power grid operator, it will be more effective to address the PV power fluctuation that can seriously increase the AGC reserve capacity.
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.
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.
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.
Power tracking control layer: it focuses on the internal operation mechanism of the energy storage power station and fully considers the cycle life of energy storage and the operation effect of the converter under different controls.
