Energy storage power optimal distribution control method for all-vanadium redox flow battery

Abstract

The invention discloses an energy storage power optimal distribution control method for an all-vanadium redox flow battery. The method comprises the following steps: indirectly acquiring and / or radiating electrolyte heat of an all-vanadium redox flow battery by using heat exchange liquid of electrolyte different from the all-vanadium redox flow battery so as to provide the heat from the electrolyte to a heat utilization mechanism; in the heat utilization mechanism, the heat is used as primary energy to be directly used for heating a corresponding production object; and the electric power generated by the all-vanadium redox flow battery is provided for the heat utilization mechanism, so that the electric power can be directly used for at least one other function of the heat utilization mechanism in a non-transduction manner.

Description

Technical field[0001]The present invention relates to the field of battery control management, and in particular, to a full vanadium flow battery energy storage power optimization allocation control method.Background technique[0002]At present, the energy storage batteries used in large-scale power generation facilities such as industrial or wind power, hydropower, and the liquid flow battery such as a full vanadium flow battery is a battery that is a more popular in a liquid flow battery. The basic principle of its discharge is to use the oxidation of the vanadium ions (divalent, trivalent, quad and five-price) to form electronics flow to discharge, due to its main electrical energy source material as an electrolyte, Therefore, the full vanadium flow battery can provide or stored in the amount of energy depends on the size of the electrolyte storage volume. During the discharge of the vanadium fluid flow battery, the positive and negative electrolyte flows from the respective electr...

Problems solved by technology

[0004] CN 205828544 U utility model patent provides an air-cooled electrolyte temperature controller utilizing a heat conducting plate and a cooling fan, but the disadvantage of using the air-cooling method is that the heat transfer coefficient of the air-cooling is low, and the cooling time is long In addition, affected by the ambient temperature, it is often necessary to introduce auxiliary cooling equipment such as a cold dryer or refrigerant, which increases energy consumption and occupies more space

The CN202651271U utility model patent introduces a water-cooled electrolyte temperature controller utilizing heat conduction pipes and cooling water. The defect of this water-cooling method is that in order to meet the requirements of water-cooling, relatively large equipment such as cooling towers need to be set, and there are The problem that the water cooling effect is greatly reduced when the ambient temperature is too high

The existing technology can also solve the problem of solute precipitation caused by the low temperature of the electrolyte when the vanadium redox flow battery is used in severe cold regions. In addition, the existing technology does not propose to adapt the heat exchanged by the heat exchange fluid to the heat that is required at the same time.
