Problems solved by technology

From the current point of view, no unified standard has been formed, and the requirements for matching with cabinet installation and system design are easily ignored in the design of existing modules, resulting in poor modularization capabilities of products
[0003] After the system voltage is raised from 1000V to 1500V, the system integration level is improved and the overall cost is reduced. The subsequent system voltage is raised to 2000V, 3000V or even higher. The adaptability of the existing energy storage modules to the system voltage is relatively poor.

Abstract

The invention provides a module screening method applied to energy storage of a power system, and the method comprises the following steps: S1, starting a program, carrying out the matching calculation of the voltage of the power system, and defining a first input packet; s2, performing installation matching calculation on an energy storage cabinet body of the power system, and defining a second input packet; s3, designing matching calculation for the power system, and defining a third input packet; s4, when the output result of the third input packet is unique, ending the process, and realizing optimal module screening of energy storage of the power system; according to the invention, by setting the input parameters, the energy storage module suitable for a plurality of voltage levels can be calculated.

Description

technical field [0001] The invention relates to the technical field of power system module screening, in particular to a module screening method applied to power system energy storage. Background technique [0002] In the construction of a new power system with new energy as the main body, the power supply characteristics and safe operation characteristics of the new power system will undergo major changes, and energy storage will play a vital role. At present, electrochemical energy storage represented by LFP has been commercially applied, and energy storage power stations are gradually developing towards GW level or even TW level. However, when applied to power system energy storage production, integration manufacturers have various definitions of energy storage modules, forming 1000V, 1500V and other systems, using thermal management solutions such as air cooling, liquid cooling, etc., and indoor installation methods Single cabinet, outdoor single cabinet, outdoor contai...
