Title
(EN) Cascade utilization energy storage battery energy control method and system for energy storage unit
(ZH) 一种储能机组的梯次利用储能电池能量控制方法和系统
Abstract
(EN)
The invention relates to a cascade utilization energy storage battery energy control method and system for an energy storage unit; the method comprises the following steps of acquiring a power commandvalue of the cascade utilization energy storage battery of each energy storage unit at the current moment; obtaining a power command value of the cascade utilization energy storage battery of each energy storage unit at the next moment according to the power command value of the cascade utilization energy storage battery of each energy storage unit at the current moment through a pre-establishedrecurrent neural network model; and adjusting the current discharging 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. By virtue of the technical scheme, the power command value is predicted through the recurrent neural network, sothat the problem that due to the fact that the power change is too large, the battery output is sharply increased is avoided, and a response can be made in advance, so that the use of the cascade utilization battery is more stable; and the energy control method of the energy storage system is optimized, and energy management efficiency of the energy storage system is improved.
