Abstract

The invention provides a method and a system for distributing real-time power of a battery energy storage power station for tracking planned output. The method comprises the following steps of reading relevant data of a battery energy storage power station in real time, and carrying out storage and management through the data; calculating a total power requirement command value of the current battery energy storage power station; calculating power command values of energy storage units in the battery energy storage power station; and summarizing the power command values of the energy storage units and outputting the summarized power command values to an external monitoring platform. The system comprises that the method for distributing the real-time power of the battery energy storage power station for tracking planned output is completed through a communication module, a data storage and management module, a tracking plan control module and a genetic algorithm control module, which are arranged on an industrial personal computer, together with the external monitoring platform, thereby being capable of realizing a function that a tracking plan curve is supported by applying the battery energy storage power station, and realizing the purposes of effectively controlling and distributing the real-time power of megawatt-grade lithium battery energy storage power stations.

Description

technical field [0001] The invention belongs to the technical field of smart grid and energy storage and conversion, and specifically relates to a real-time power control method based on a large-scale lithium battery energy storage power station, especially suitable for the energy storage power station when the megawatt-level battery energy storage power station participates in the tracking plan output. Real-time power distribution of energy storage units in the station and energy management of energy storage power stations. Background technique [0002] With the continuous development of batteries and their integration technologies, it has gradually become a feasible solution to apply large-scale battery energy storage power stations to participate in tracking plan output. The battery energy storage unit in the battery energy storage power station has the advantages of fast response and short start-stop time compared with the traditional generator set, and will play an impo...
