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.
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.
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 configuration of the storage system in the new energy grid is divided into two modes: distributed and centralized configuration. The configuration methods are widely applied in wind farms. The distributed configuration is applied on the excitation DC link of a wind turbine or on the output terminal of each wind turbine.
In the power computational distribution layer, the operating mode of the ESSs is divided by establishing the working partition of the ES. An adaptive multi-energy storage dynamic distribution model is proposed to solve the power distribution problem of each energy storage power station.
When the energy storage absorption power of the system is in critical state, the over-charged energy storage power station can absorb the multi-charged energy storage of other energy storage power stations and still maintain the discharge state, so as to avoid the occurrence of over-charged event and improve the stability of the black-start system.
