Substation energy storage capacity configuration method and device, computer equipment and storage medium

Abstract

The invention relates to a substation energy storage capacity configuration method and device, computer equipment and a storage medium. The substation energy storage capacity configuration method comprises the steps: obtaining all load curves of a substation in one year and obtaining a target load curve according to all the load curves and the peak-valley difference of the target load curve; obtaining the standard bearing load value of the substation and removing a curve corresponding to the standard bearing load value from the target load curve to obtain an effective load curve; obtaining thepeak regulation proportion of the substation; determining a daily load difference interval according to the peak regulation proportion and the peak-valley difference; determining an upper load boundary line and a lower load boundary line corresponding to end values of the daily load difference interval in the target load curve; and determining the minimum energy storage capacity required by the substation according to a plurality of discharge energy storage capacities and the plurality of charging energy storage capacities so as to obtain the target energy storage capacity. According to the substation energy storage capacity configuration method and device, the computer equipment and the storage medium, the problem of unreasonable energy storage capacity configuration in the traditional scheme can be solved.

Description

technical field [0001] The present application relates to the field of substation technology, in particular to a substation energy storage capacity configuration method, device, computer equipment, and storage medium. Background technique [0002] With the acceleration of urbanization and the increase of regional power load density, this has brought great challenges to the planning and construction of the power grid under the traditional model, which increases the peak-valley load difference of the power grid and also poses a threat to the safety of the power system. Running brought problems. [0003] Aiming at the problem of increasing grid load, researchers have designed power energy storage technology, that is, adding energy storage devices in substations, so that the energy storage devices can bear the excess load that substations cannot bear. However, it is not realistic to invest heavily in the construction of energy storage devices at present. Therefore, how to conf...
