A virtual energy storage system

Abstract

The invention discloses a virtual energy storage system which comprises a virtual battery, an energy storage system simulator, a virtual power supply changeover system, a virtual data acquisition and supervisor control system and a virtual battery management system, wherein the energy storage system simulator is respectively connected with the virtual battery, the virtual power supply changeover system, the virtual data acquisition and supervisor control system and the virtual battery management system in a communication mode. The virtual energy storage system can be utilized to implement input / output of virtual data and signals among functional modules. The virtual energy storage system can implement the functions of setting the battery protection parameters, saving the history failure data and the like. Compared with the existing scheme, the virtual energy storage system does not need real battery modules or hardware equipment with various functions, thereby saving the huge equipment cost; and the virtual energy storage system does not need real current or voltage, can implement complete digitized analog, is simple to operate and convenient for testing, and has favorable real-time performance.

Description

technical field [0001] The invention relates to the field of energy storage systems, in particular to a virtual energy storage system. Background technique [0002] With the advancement of science and technology and the development of society, people pay more and more attention to the development of new energy. In the field of new energy, a smart microgrid energy storage system is usually composed of a power management unit (PMU), an energy management system (EMS), battery management system (BMS) and battery pack system. [0003] Among them, the battery management system (BMS) is mainly composed of two parts: the battery control unit (BCU) and the battery measurement unit (BMU). The battery control unit (BCU) sends out the required battery voltage, current and other information. The battery measurement unit (BMU) is responsible for collecting the voltage module and uploading it to the battery control unit (BCU). The data collected by the battery measurement unit (BMU) is di...

Problems solved by technology

[0004] However, purchasing a large number of batteries for battery modules and various devices of these energy storage systems requires a large amount of expenses, not to mention inverters, power management units (PMU), power conversion systems (PCS) and other storage systems. Energy system equipment, and because the energy storage system composed of these equipment is bulky, it is not easy to move, and it is not suitable for testing anytime and anywhere
