Abstract

The invention provides a large-scale battery energy storage system based on temperature field control and an energy dispatching method thereof, and belongs to the technical field of batter temperature field control. The large-scale battery energy storage system is formed by connecting a plurality of energy storage power modules in parallel, and each energy storage power module comprises a battery pack and a bidirectional electrical energy conversion topology circuit based on batteries. Each bidirectional electrical energy conversion topology circuit based on batteries comprises a bidirectional direct-current and direct-current conversion module, a bidirectional direct-current and alternating-current conversion module and a voltage output end. The system can realize that the energy storage system can protect and maintain the battery packs while meeting the power requirement of energy storage, so that the battery packs work in a safe and proper temperature range, and the service lives of the batteries are finally prolonged.

Description

technical field [0001] The invention relates to the technical field of battery temperature field control, in particular to a large-scale battery energy storage system based on temperature field control and an energy scheduling method thereof. Background technique [0002] In the current battery application field, the battery heat dissipation technology usually adopts external forced cooling (air cooling, water cooling, etc.), and the goal of the heat dissipation design scheme is to heat uniformly, to ensure that the battery works in a safe temperature range, and to prolong the service life of the battery. . In large-scale energy storage applications, in order to meet the requirements of energy storage power and capacity, it is usually necessary to connect single cells in series and parallel to form a group, and cooperate with the electric energy conversion device to provide or absorb power to the upper power system. The working environment of large-scale energy storage devi...
