A micro-grid architecture, permission changing method and terminal

Abstract

The application discloses a micro-grid architecture, a permission changing method and a terminal, changes the original setting that an external meter is only connected with a master station system in communication, and is connected with the external meter in communication by the master station system and a substation system respectively, so that each substation under the micro-grid architecture can acquire power information of the external meter, so that when communication failure or program failure occurs in the master station system, any substation can upgrade the permission to the master station permission according to the external meter information, and the charging and discharging control and protection control of the substation system and other substation systems are performed, and the stability of the micro-grid architecture operation is improved; meanwhile, the energy storage units of the substation system are electrically connected with the master station system through circuit breakers, and the electrical equipment of the master station system is powered, when the energy storage units of the substation system for powering the master station system fail, the circuit breakers can be used to switch to the energy storage units of other substation systems at any time, so that the master station system is prevented from stopping due to power failure, and the working continuity of the micro-grid architecture is improved.
