Ouagadougou energy storage station intelligent auxiliary control

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 is the power deficiency of the energy storage system?

The wind power and energy storage system is self-starting in 0–1.5 s, the system power deficiency is 0.3 MW. The power of ESSs is distributed by 1:1, and each all energy storage power stations absorbs 0.15 MW. The power deficiency of the system is 0.6 MW in the 1.5–2.5 s, and the absorbed power of each energy storage power station is 0.3 MW.

What is adaptive multi-energy storage coordinated optimization?

Aiming at the over-charge/discharge, an adaptive multi-energy storage coordinated optimization method is proposed. The power allocation is based on the chargeable/dischargeable capacity and limit power. A black-start model of multiple wind power and energy storage system model is established.

What is the output power of energy storage charging?

The output power of energy storage discharging is positive, while the output power of energy storage charging is negative. When the energy storage station participates in the black-start power dynamic distribution, the reference charge-discharge power/of the ith energy storage station can be obtained from the following equation.

What is the maximum chargeable/dischargeable power of energy storage?

Meantime, combined with wind power prediction, the maximum chargeable/dischargeable power of energy storage is the maximum deficiency of the wind power compared with the auxiliary machine of the thermal power unit, and the energy storage capacity required in the black-start period can be obtained.

What is total output power of energy storage power station?

And the actual output power of each energy storage power station controlled by the converter was Pbn, which can constitute the total output power of ESSs. The total output power is the difference between the output power Pwind of wind power cluster and the auxiliary power Pref of thermal power plant.
