Novel energy storage system experiment platform and working method

Abstract

The invention discloses a novel energy storage system experiment platform and a working method, and the experiment platform comprises an array simulation module, an energy storage element and a management module thereof, a charging and discharging control module, a main power module, an intelligent control module, a DC load module, a serial port management module, an LAN management module and an upper computer. The array simulation module is used for providing an energy source for the energy storage element. The energy storage element and the management module include a lead-acid battery packand its management module, a lithium battery pack and its management module, a supercapacitor module and its management module. The charging and discharging control module includes a lead-acid batterypack charging and discharging control module, a lithium battery pack charging and discharging control module, and a super capacitor module charging and discharging control module. The main power module is used for providing working power for the experiment platform. The intelligent control module is used for controlling the charging and discharging strategy of the energy storage element. The DC load module is used for stimulating electrical equipment. The upper computer receives and displays the operating data and the operating state of the energy storage element through the serial port management module and the LAN management module.

Description

technical field [0001] The invention relates to the technical field of new energy experiment platforms, in particular to a novel energy storage system experiment platform and a working method. Background technique [0002] Due to the intermittent and uncontrollable characteristics of new energy power generation itself, incorporating it into the large power grid will cause power fluctuations and have a negative impact on the quality of power supply. Therefore, it is of great significance to construct a hybrid energy storage system using diversified energy storage technologies. [0003] Existing energy storage components mainly include lead-acid batteries, lithium batteries and supercapacitors. Among them, the price of lead-acid batteries is relatively low, but the power density is small, the cycle life is short, it cannot meet the needs of fast charging and discharging, and the volume and quality are large; the price of lithium batteries is slightly higher, but compared with...
