The invention relates to the technical field of power grid dispatching, in particular to a smart electric energy meter for short-term prediction of power consumption of a user. The smart electric energy meter comprises an electric energy meter gauge, a programmable controller, a storage module, a communication module and a plurality of terminal modules. The terminal modules include connecting bodies, electronic switches, and communication units. The connecting bodies are connected in series with an electrical appliance; control terminals of the electronic switches are connected with the connecting bodies; the electronic switches are in conduction when currents flow through the connecting bodies; and the communication units are connected with the connecting bodies by the electronic switches. After the communication units are electrified, preset messages are sent to the communication modules; the programmable controller determines an electrical appliance that is started by the user currently based on information received by the communication modules. According to the invention, the smart electric energy meter has the following benefical effects: the terminal modules are connected with the electrical appliance of the user and thus the electrical device that is started by the user currently is reported; and statistics of the power consumption rule of the electrical device is performed, so that the short-term load of the user can be more accurately predicted and the basis is provided for dispatching of a power generating set.
Description
technical field [0001] The invention relates to the technical field of power grid dispatching, in particular to an intelligent electric energy meter for short-term prediction of user electricity consumption. Background technique [0002] In the dispatching work of the power grid, the most important thing is to predict the load, so as to formulate the generator set plan in a targeted manner, reduce the standby set, and achieve the purpose of reducing the operating capacity and reducing the cost. At present, the accuracy of short-term prediction of users is still insufficient. As a result, generator sets still need to prepare sufficient reserve capacity to deal with short-term changes in electricity consumption. The spare capacity is not used, and the cost of it needs to be borne by the power plant itself. It increases the operating cost of the power plant and ultimately increases the power consumption burden of the user. Accurately realizing short-term forecasting of elect...
