REAL-TIME POWER DISTRIBUTION METHOD AND SYSTEM FOR LITHIUM/LIQUID FLOW BATTERY COMBINED ENERGY STORAGE POWER STATION

摘要

A real-time power distribution method and system for a lithium/liquid flow battery combined energy storage power station. The system includes a communication module (10), a data storage and management module (20), a total power coordination and control module (30) and a real-time power distribution module (40). The method includes: A) reading and storing a total active power real-time demand value of a battery energy storage power station and real-time data when the power station operates; B) calculating the active power command values of a lithium battery energy storage substation and a liquid flow battery energy storage substation in the battery energy storage power station; C) calculating an active power command value to be distributed to each lithium battery energy storage unit and each liquid flow energy storage unit respectively; and D) summarizing the active power command value to be distributed to each lithium battery energy storage unit and each liquid flow energy storage unit and then outputting same to the battery energy storage power station. The method and system can not only complete the real-time power distribution of each energy storage unit in the battery energy storage power station but can also realize the effective control and distribution purpose of the real-time power of the lithium/liquid flow battery combined energy storage power station.
