Title:
ENERGY CONTROL METHOD AND SYSTEM FOR CASCADE UTILIZATION ENERGY STORAGE BATTERY OF ENERGY STORAGE UNIT
Document Type and Number:
WIPO Patent Application WO/2020/107542
Kind Code:
A1
Abstract:
Disclosed are an energy control method and system for a cascade utilization energy storage battery of an energy storage unit. The method comprises: acquiring a power command value of a cascade utilization energy storage battery of each energy storage unit at the current moment (101); according to the power command value of the cascade utilization energy storage battery of each energy storage unit at the current moment, using a pre-established recurrent neural network model to acquire a power command value of the cascade utilization energy storage battery of each energy storage unit at the next moment (102); and adjusting the current discharge rate of the cascade utilization energy storage battery of each energy storage unit according to the power command value of the cascade utilization energy storage battery of each energy storage unit at the next moment (103). In the method, the power command value is predicted using a recurrent neural network, so that the surge in a cascade utilization battery output when a power change is too large is avoided, a response can be made in advance, and the cascade utilization battery can be used more stably. In the method, an energy control method for an energy storage system is optimized, and the energy management efficiency of the energy storage system is improved.
