6 FAQs about [Several energy storage power stations were randomly inspected]
Why does a sectional energy storage power station fail?
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.
How to solve power distribution problem in energy storage power stations?
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.
Where should the energy storage power station be located?
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.
What is the power deficiency of energy storage power station?
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.
Can energy storage power stations be controlled again if blackout occurs?
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.
What happens when energy storage absorption power is in critical state?
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.
