Abstract

The invention relates to a power distribution method and system for an electrochemical energy storage power station. The method includes: when the power demanded by grid dispatching is less than the sum of the rated capacities of all electrochemical energy storage power stations, according to the obtained grid dispatching instruction information and electrochemical energy storage power stations The operation statistical information of the energy storage power station determines the technical evaluation index of the electrochemical energy storage power station, and uses the comprehensive evaluation coefficient of the electrochemical energy storage power station to participate in the grid dispatch to determine the power allocated by each electrochemical energy storage station; when the power grid dispatch requires power When the amount is greater than or equal to the sum of the rated capacity of all electrochemical energy storage power stations, the power distributed by the electrochemical energy storage power station is determined by using the power grid dispatching demand power; the technical scheme of the present invention corrects the electrochemical energy storage power station by rolling update the evaluation coefficient The new power distribution algorithm improves the rationality of the power distribution of the grid dispatching electrochemical energy storage power stations, and at the same time effectively guides the operator's decision to dispatch the electrochemical energy storage power stations, and promotes the stable operation of the power grid.
