Abstract

The invention provides a method and a system for controlling power of a battery energy storage power station based on an ant colony algorithm. The method comprises the steps of: A, reading relevant data of the battery storage power station in real time and storing the data; B, determining an energy storage unit participating in power distribution of the battery energy storage power station in real time through the ant colony algorithm; C, calculating a power command value of the energy storage unit participating in the power distribution; and D, storing the power command value calculated in the step C of the energy storage unit and outputting the power command value. The system comprises a communication module, a data storage module, a management module, an ant colony algorithm control module and a power distribution control module. The method and the system for controlling complete power control of the battery energy storage power station based on the ant colony algorithm through the modules in an industrial personal computer, transmit data to an external monitoring platform so as to be monitored, and can realize the purposes of effectively controlling and distributing the real-time power of megawatt-grade 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 an ant colony algorithm-based power control method and system for a battery energy storage power station, and is especially suitable for grid-connected systems of large-scale distributed and centralized energy storage power stations The real-time power and energy management method of the battery energy storage unit. Background technique [0002] With the continuous development of batteries and their integration technologies, the application mode of large-scale distributed and centralized battery energy storage power stations will gradually become a preferred solution. Several large-capacity energy storage batteries commonly used in battery energy storage systems include sodium-sulfur batteries, flow batteries, and lithium-ion batteries. [0003] By reasonably controlling the converters connected to the energy storage equipment, the...
