Energy storage power station active scheduling control method and system with peak regulation and frequency modulation functions

Abstract

The invention discloses an energy storage power station active scheduling control method and system with peak regulation and frequency modulation functions. The method comprises the following steps: determining a time interval, peak regulation power and peak regulation energy of each energy storage power station for peak up-regulation and peak down-regulation; determining the capacity of a converter capable of being used for frequency modulation based on the working condition time period of each energy storage power station at the current moment; determining an automatic power control instruction of each energy storage power station at the current moment according to the capacity of the converter capable of being used for frequency modulation and a preset automatic power control strategy, and issuing the automatic power control instruction to the energy storage power stations for execution. The invention aims to make full use of the limited active power regulation capability of the energy storage power station, meet the requirements of peak regulation and frequency modulation, improve the utilization efficiency of the converter, and realize the active power scheduling control of the energy storage power station with the functions of peak regulation and frequency modulation; on the basis of not influencing the peak regulation capability, the frequency modulation capability of the energy storage power station is effectively enhanced, and the utilization efficiency of the converter is remarkably improved.

Description

technical field [0001] The invention relates to power system dispatching technology, in particular to an active power dispatching control method and system of an energy storage power station that takes into account both peak regulation and frequency regulation functions. Background technique [0002] With the goal of "carbon peak" and "carbon neutrality", the proportion of thermal power stations has gradually decreased and the proportion of new energy power stations has gradually increased. It will play an increasingly significant role in the dispatch control of power grid operation. In terms of active power regulation, energy storage power stations have the advantages of fast regulation speed, less equipment damage, and no need to abandon wind, water, and light. Peak shaving is one of the main functions of active power support of energy storage power stations at present. When the energy storage power station is peak-shaving, at most 2 charges and 2 discharges are performe...
