Embodiment Construction

[0069] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0070] It should be noted that peak shaving means that energy-consuming regions can use energy storage devices in the region to supply energy to their energy-consuming devices, helping the main grid to share part of the energy supply demand. The peak shaving rate in the following method embodiments refers to the contribution ratio of the energy storage equipment in each area to be powered to the energy supply of the main grid side.

[0071] The method for constant capacity of distribution network energy storage equipment provided by the embodiment of the present invention ...

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.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a capacity constant method, device, device and storage medium for energy storage equipment of a distribution network. Background technique [0002] Energy storage is an important part of the Energy Internet system, and has become an indispensable supporting technology in the fields of renewable energy utilization, distributed power generation, and microgrid. The application of energy storage technology runs through all links of power generation, transmission, distribution, and power consumption in the power system. It can alleviate the peak load power supply demand, improve the utilization rate of existing grid equipment and the operating efficiency of the grid, and can effectively respond to grid failures. generation, improve power quality and power efficiency, so as to meet the requirements of economic and social development for reliable power supply and efficient power...
