The invention relates to the technical field of distribution network dispatching, in particular to a quick response energy storage device for a distribution network, which comprises a plurality of user side energy storage devices and a control center, and is characterized in that the plurality of user side energy storage devices are deployed at a user home-entry line and are connected with the home-entry line; the user side energy storage device comprises a distribution network monitoring device, a charging and discharging device, a communication unit and a control unit, the distribution network monitoring device is connected with the home-entry live wire and monitors the voltage of the home-entry live wire, the charging and discharging device is connected with the home-entry live wire, and the distribution network monitoring device, the charging and discharging device and the communication unit are all connected with the control unit. The communication unit is in communication connection with the control center. The device has the substantive effects that the user-side energy storage equipment provides quick-response load regulation and is closest to the user, the load regulation is provided for the single user very conveniently and effectively, peak load shifting is realized, and the operation of the power distribution network is more stable.
Description
technical field [0001] The invention relates to the technical field of distribution network scheduling, in particular to a fast-response energy storage device for distribution networks. Background technique [0002] With the development of new energy, the development of fossil energy with regulation ability under the situation of energy dual control is limited, the proportion is reduced, and the self-regulation ability is sharply squeezed out. In the traditional mode, there is a natural contradiction between safety and efficiency. Efficiency optimization is accompanied by a decrease in safety margin, and an increase in safety and stability will reduce operational efficiency. Power grid operation is squeezed by sources, grids, loads, and storage. The space for maneuvering and adjusting the grid has shrunk sharply. It is urgent to change the development mode of the grid, from a small amount of centralized regulation to massive decentralized response, and greatly mobilize adjus...
