With the Test instruction issued at 1 am on August 28, the electricity consumption of 200 households around the 10kV New West line in Zhenjiang Yangzhong was separated from the large power grid, all of which were constructed by a nearby network type. Energy storage the power station provides power supply for 2 hours. This means that Jiangsu has successfully realized the city's "Power Bank" independent power supply for the first time, which is of great significance to broaden the application scenarios of energy storage and enrich the means of maintaining power supply.

The grid-type energy storage power station is equivalent to a stable city 'power Bank '. When the surrounding lines fail, the energy storage can be started spontaneously, at the same time of breaking away from the large power grid, a micro-grid is built in a certain area to supply power to the load in the micro-grid." Liu Feng, the head of the research and development of the energy storage power station project and the deputy manager of the Ministry of wisdom and energy of Guodian Nanrui Technology Co., Ltd, said.

The reporter learned from State Grid Jiangsu Electric Power Co., Ltd. that this grid-type energy storage power station is the first grid-type energy storage power station project in Jiangsu led by the company this year. It consists of two storage battery containers, A network-type optical storage integrated cabin and auxiliary energy management system are composed to accelerate the expansion of new scenarios of energy storage and power grid integration applications.

The National Development and Reform Commission and other departments have previously issued the "action plan for accelerating the construction of a new power system (2024-2027)", proposing special actions such as carrying out the power system stability guarantee action, it includes promoting the application of network technology.

"Grid-type energy storage technology is generally applicable to areas with long line radius. The power grid in such areas is often single in structure. Once a fault occurs, it takes a certain time for the repair team to arrive at the site. During this period, the grid-type energy storage power station can independently maintain the power supply in the region, minimizing the impact of power failure on users." Jin Pengfei, a technician of State Grid Yangzhong power supply company, said.

According to Jin Pengfei, grid-type energy storage technology can also cooperate with new energy sources such as photovoltaic to improve new energy sources.The ability to absorb nearby and locally. Taking the energy storage power station in Yangzhong city as an example, the local photovoltaic absorption rate in the region can be increased from 60% to 90% by cooperating with the adjacent centralized photovoltaic power station, effectively reduce the operating pressure caused by insufficient consumption of new energy to the power grid.
