Abstract

The invention discloses an access mode and a control method of an energy storage system. The access mode of the energy storage system comprises a power distribution network used for receiving electricenergy and/or outputting the electric energy; a transformer which is connected with the power distribution network, receives the electric energy and is used for converting the voltage in the electricenergy; a first circuit breaker which is connected with the low-voltage side of the transformer and is used for controlling the connection or disconnection of the transformer; a bus which is connected with the first circuit breaker and is used for receiving electric energy on the power distribution network; a second circuit breaker, a first end of the second circuit breaker is connected with thebus, and a second end of the second circuit breaker is connected with a load; a third circuit breaker, a first end of the third circuit breaker is connected with the second end of the second circuit breaker; and a first energy storage system which is connected with a second end of the third circuit breaker and is used for providing electric energy for the load branch. The access mode can shorten processing of heavy overload of the transformer and improve the automation degree.

Description

technical field [0001] The invention relates to the technical field of power system energy storage, in particular to an access method and control method of an energy storage system. Background technique [0002] With the improvement of people's living standards, the social demand for electricity continues to increase. During the peak period of electricity consumption, especially in summer and winter, the residential electricity load increases too fast, and the transformer on the distribution line is overloaded due to excessive load. The frequent accidents of transformer burnout and frequent trips and power outages of the power grid. [0003] In the related art, there are problems of long time consumption and low degree of automation in solving the heavy overload of the transformer. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes an ener...
