Abstract

The invention discloses an energy management method, device and system. The energy management system is supplied with power by a distributed power supply and / or a power grid, and surplus electricity generated by the distributed power supply is stored by a preset energy storage device. The energy management system comprises at least one load, an information acquisition unit, a control unit and a plurality of relays, wherein the information acquisition unit acquires working parameters of a plurality of target objects to obtain multiple items of parameters; the plurality of target objects comprise at least one of the following objects: the distributed power supply, at least one load and the energy storage device; the control unit controls the plurality of relays to work according to multipleitems of parameters acquired by the information acquisition unit and load information corresponding to at least one load; and the plurality of relays control at least one load to work. The invention solves the technical problem that in the related art, effective management cannot be implemented on a plurality of loads in the energy management.

Description

technical field [0001] The present invention relates to the technical field of energy management, in particular to an energy management method, device and system. Background technique [0002] In related technologies, for energy management, the traditional power supply mode and energy control mode are generally used, that is, the electric energy input through the external power grid, and the electricity price is fixed, and generally there will be no obvious changes. In addition, for energy The electricity consumption management method in management generally controls all the loads through the control center in a city or a community, but it cannot flexibly adjust the energy storage structure and energy consumption structure according to the change of electric energy. Especially for load management among multiple users, self-regulation cannot be realized in the energy management structure, and users can only control the switches of each load through control switches or remote ...
