Intelligent electric meter system for residents for intelligent smart grid

Abstract

The invention discloses an intelligent electric meter system for residents for an intelligent smart grid. According to the intelligent electric meter system for the residents for the intelligent smart grid, one intelligent electric meter is arranged in home of each resident, two control terminals are respectively arranged on each controlled electric appliance and each user switch, and each distributed power supply is provided with a distributed power supply access device; each control terminal and the distributed power supply access device are interconnected through a PLC (Programmable Logic Computer) communication network, and the intelligent electric meter and a high-class measuring system AMI (Advanced Metering Infrastructure) carry out information interaction. The intelligent electric meter system is suitable for the residents having tiered pricing for electricity and time-sharing pricing for electricity, and aims at minimum electric charge expenditure of users, and is used for intelligently controlling the electric appliances and the distributed power supplies of the residents so as to realize peak clipping and valley filling of the electric charge, and provide power supply quality and power supply reliability.

Description

technical field [0001] The invention relates to the fields of smart homes, smart meters and smart grids, in particular to a smart meter system for residential users suitable for smart grids. Background technique [0002] In the era of smart grid, with the help of advanced information and communication technology, it is possible to perform load response according to dispatching requirements, which can solve the large-scale access of clean energy to the grid. All loads of power users, especially elastic loads, are no longer randomly put into the grid, but Organized and planned to invest in the power grid. See Yin Shugang, Miao Wenjing, Bai Keming (Yin Shugang, Miao Wenjing, Bai Keming). Author: Discussion of quasi real-time price strategy. Power DSM, 2011, 13( 1): 20-23. This requires information interaction between the power supply department and residential users, allowing power users to actively participate in the power market and power services, and realizing peak-shavin...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the inability of traditional smart meters to charge household users according to the ladder electricity price and time-of-use electricity price; the inability to realize the intelligent control of household appliances according to the ladder electricity price and time-of-use electricity price, so as to make the electricity fee the lowest; To solve the problem of realizing intelligent control of distributed power sources with the time-of-use electricity price and maximizing their income, the invention provides a smart meter system for residential users suitable for smart grids, which can realize peak-shaving and valley-filling of power loads, improve power supply quality and power supply reliability
