Capacity constant method, device, equipment and storage medium for energy storage equipment in distribution network

Abstract

The invention relates to a method, apparatus, apparatus and storage medium for fixing the capacity of an energy storage device of a distribution network. The method comprises acquiring the maximum load power from the area to be supplied to the grid side in a preset operation period according to the minimum peak clipping ratio requirement of the grid side; determining the maximum energy transmission power generated to the grid side under the current iteration times of the area to be supplied; and determining the maximum load power generated to the grid side according to the minimum peak clipping ratio requirement. According to the load demand curve of the power supply area to the grid side in the operation cycle and the maximum energy transmission power under the current iteration number, determining a first energy storage chargedischarge power curve required by the energy storage device in the operation period, and calculating a first total energy consumption and a first total energy supply of the energy storage device in the operation period according to the first energy storage chargedischarge power curve. The target capacity of the energy storage device is determined based on the first total energy consumption, the first total energy supply, and the maximum energy transmission power under the current number of iterations. The target capacity of the energy storage device is determined based on the first total energy consumption, the first total energy supply, and the maximum energy transmission power under the current number of iterations. The invention can improve the peak clipping effect of the energy storage device and ensure the energy supply reliability of the energy storage device.
