Allocation of energy storage power stations

How to solve power allocation problem in hybrid energy storage system?

Addressing the power allocation issue of the hybrid energy storage system, an optimization algorithm (Arithmetic Optimization Algorithm, AOA) combined with Variational Mode Decomposition (VMD) is employed to solve the model.

How is energy storage power station distributed?

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.

Why do energy storage power stations output more power?

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.

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.

How does the energy storage power station absorb the abundant power?

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.

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.
