Resident intelligent energy management system suitable for intelligent power grid

Abstract

The invention discloses a resident intelligent energy management system suitable for an intelligent power grid. Due to the adoption of the resident intelligent energy management system, peak and off peak load regulation of a power load is realized, and the power quality and power reliability are improved. An intelligent energy management controller and an intelligent electric meter are arranged in the home of each resident; a control terminal is arranged on each controllable domestic appliance and a user switch respectively; a distributed power supply accessing device is arranged on each distributed power supply; the controller is connected with the control terminal and the distributed power accessing device through a Zigbee wireless communication network; the intelligent electric meter is connected with the distributed power supply accessing device and the controllable domestic appliance; the controller is communicated with the intelligent electric meter through a bus; the intelligent electric meter is further connected with the secondary sides of a voltage mutual inductor and a current mutual inductor; the controller undergoes information interaction with a high-level measuring system AMI (Advanced Metering Infrastructure) of a main station through Ethernet communication; the controller is used for controlling switching of the control terminal and the distributed power supply accessing device; the control terminal is used for submitting the state of the switch to the controller; the controller is used for monitoring the state of the switch.

Description

technical field [0001] The invention relates to the fields of smart home and smart grid, in particular to an intelligent energy management system for residential users suitable for smart grids. Background technique [0002] Driven by various factors such as energy, environment, economy, and politics, smart grid has become the development direction of the future power system. At present, both developed and developing countries are actively transforming traditional power grids into smart grids. Conserving energy and protecting the environment are major long-term policies of our country. Therefore, our country is vigorously developing smart grid construction. Smart grid is an interactive grid, which requires information interaction between the power supply department and residential users, so that power users can actively participate in the power market and power services, and realize peak-shaving and valley-filling of power loads to improve power supply quality and reliabilit...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the fact that the traditional household appliance energy management system cannot realize the intelligent control of household appliances according to the real-time electricity price situation, so that the electricity fee expenditure is the lowest. The highest problem is to provide an intelligent energy management system for residential users suitable for smart grids, to realize peak-shaving and valley-filling of power loads, and to improve power supply quality and reliability
