Abstract

The invention relates to an energy management device and system. The energy management device comprises at least two energy sensors and a concentrator, wherein the energy sensors are connected with at least two energy terminals on a user side respectively and used for collecting energy data of the energy terminals according to a time series; the concentrator is connected with the energy sensors and used for conducting analysis through combination with rated parameters and service data of the energy terminals on the basis of the energy data so as to determine the working conditions of the energy terminals and transmitting scheduling instructions to the energy sensors according to the determined working conditions so as to enable the energy sensors to be capable of responding to the scheduling instructions and controlling the working conditions of the energy terminals. The energy data, collected by various types of energy sensors, of various types of energy terminals can be gathered and analyzed comprehensively through the concentrator, so that the energy use condition of the user side is analyzed more accurately, and the requirements of users for energy scheduling on the condition that various kinds of energy are used can be met.

Description

technical field [0001] The invention relates to the field of energy management, in particular to an energy management device and system. Background technique [0002] Under the background of actively carrying out energy conservation, emission reduction and environmental protection, new energy and renewable energy are developing rapidly. Therefore, the energy consumed by users not only includes electricity from the grid, water from the water company, and natural gas from the gas company, but also includes user-owned production equipment, such as electricity produced by photovoltaic or wind power plants, or from user-provided energy storage. equipment power, etc. In other words, users are no longer a single energy consumption center, but gradually become energy interactors with dual identities of energy production center and energy consumption center. [0003] In recent years, due to the huge demand for energy saving, emission reduction and safety on the user side, the Unite...
