Abstract

The invention discloses a control method and device of a flow cell system. The control method comprises the steps that an optimal control function of the flow cell system is updated according to a preset period, wherein the optimal control function is used for representing the relation between optimal control parameters of the flow cell system and monitoring parameters; current monitoring parameter values of the flow cell system are obtained; current optimal control parameter values are determined by utilizing the optimal control function according to the current monitoring parameter values; based on the determined current optimal control parameter values, the flow cell system is controlled. The technical problem that flow cell system control methods in the related arts cause deviation or even failure of optimizing points.

Description

technical field [0001] The invention relates to the field of control of a liquid flow battery system, in particular to a control method and device for a liquid flow battery system. Background technique [0002] System efficiency is one of the most important indicators to measure the performance of a flow battery system. In order to improve system efficiency, on the one hand, the energy conversion efficiency of the key component battery stack can be improved, and on the other hand, the energy consumption of auxiliary components can be reduced. However, the existing technologies only dynamically adjust the system operation control parameters through the monitoring of the system state of charge (SOC, State of Charge) or other monitoring parameters from the perspective of a single cycle, so as to achieve the purpose of optimizing system efficiency. However, in actual operation, if the monitoring method of monitoring parameters such as SOC determined by the initial state of the ...
