Abstract

The invention discloses a user-side energy storage device access control method, which includes setting an energy storage device on the user side of a power grid, and connecting the energy storage device with the power grid and user loads; obtaining information on the power grid and the energy storage device Operating status and operating data; control the connection relationship between the user-side energy storage device, the grid, and the user load, and realize the access control of the user-side energy storage device. The access control method of the user-side energy storage device provided by the present invention proposes a set of mature The reliable access control method of the user-side energy storage device can maximize the utilization of the user-side energy storage device, and ensure the stable and reliable operation of the power grid, and the method of the invention is scientific, reliable, simple and easy to implement.

Description

technical field [0001] The present invention specifically relates to a method for access control of a user-side energy storage device. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. [0003] The peak-to-valley balance of the power grid is one of the keys to the reliable and stable operation of the power grid; in order to cope with the large load of the power grid during the peak period of power consumption, the power grid often reserves a large reserve load. In order to improve the operating efficiency and reliability of the power grid, installing energy storage devices on the user side is a common solution for power grids. After the energy storage device is installed on the user side, when there is excess electricity from the grid, th...
