AI Customer ServiceThe 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.
Among the rest, compared with the wind turbine side and the point of grid-connected wind power cluster, it is more appropriate to configure the energy storage power station in the gathering place of the wind farm group.
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.
The energy storage power station absorbs the abundant power according to the ratio of chargeable/dis-chargeable capacity by 5:1. Up to 3.5 s, the ES is continuously discharged. If not corrected by Δ SOC, critical-charge ES 2 # will continue the critical discharge.
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.
According to the above distribution method, when the ESSs outputs power, the unit with higher discharge capacity outputs more power, so as to avoid the occurrence of pre-shutdown and over-discharge due to the output power of the energy storage power station with lower discharge capacity.
