What is a peak load period?

Midday to evening is the peak load period, where BESS is used for discharging to relieve the pressure of peak power consumption. The interval of PSVF applications can be used for FR. The overall regulated power has a maximum unidirectional demand of around 45 MW and a short duration, while most power demand falls within 20 MW.

Are battery energy storage systems a practical and flexible resource?

More flexible resources are needed to supplement and complement regulation to maintain the safe and stable operation of the grid . Battery energy storage systems (BESS), as a practical and flexible regulation resource , have been widely studied and applied for the characteristics of energy time-shifting and power fast-accurate response .

Can energy balancing reduce peak-to-Valley load difference?

The use of BESS to achieve energy balancing can reduce the peak-to-valley load difference and effectively relieve the peak regulation pressure of the grid . Lai et al. proposed a method that combines the dynamic thermal rating system with BESS to reduce system dispatch, load curtailment, and wind curtailment costs.

How does power load affect power efficiency?

With the increase of power load, the peak-to-valley difference of load is increasing, which will affect the generation efficiency of the unit and the operation stability of the system.

Why are the initial charge state and capacity parameters set?

Specifically, the initial charge state and capacity parameters of the BESS are set so that when the BESS is operated under the corresponding operating conditions, the complete charge and discharge cycle is completed and the charge state of the BESS can be restored to the initial state or as close to the initial state as possible.
