Research On The Household Intelligent Power Management System

The residential electricity is an important aspect of smart grid. Traditional residential electricity consumption is based on passive mode, which power supply bureau only takes on the electricity bill by collecting the electrical energy expended of resident, however, they cannot exchange information with the power supply bureau as well as taking participate in the management and operation of the power supply bureau. Household intelligent power management system is based on AMI(Advanced Material Information) and should be adopted to much technology, such as information collection, network communication, high-speed control, data analysis, data storage, internet of things etc. The system allows consumers le arn their electricity consumption in real time and communicate with the power supply bureau. Moreover, it makes a reasonable electricity schedule which aims at reducing the electricity fee for consumers. In order to achieve the goal, a household intellige nt power management system has been developed in this paper, an electric programming model has been established, and an optimal control algorithm based on genetic algorithm has been presented for clients.To begin with, a series of wireless communication technology, such as Bluetooth, Wifi, Zig Bee and GPRS has been analyzed. The household intelligent power management system has been set up based on Zig Bee and GPRS technology which consists of household intelligent power management system, intelligent interactive terminal/ socket, intelligent mobile phone APP and third-party servers. According to the actual demand of customers, the mainly function of a system has been identified. After analyzing the SMS, Fix IP servers, the third-party servers and VPS, the VPS has been adopted to realize the communication between intelligent interactive terminal and intelligent switch/socket.Secondly, functions of intelligent interactive terminal, intelligent switch/socket and intelligent mobile phone APP have been designed. The communication protocol between intelligent interactive terminal and the intelligent socket as well as intelligent interactive terminal and intelligent mobile photo has been devised. As well as the hardware circuit of intelligent interactive terminal ha s been established based on STM32F407ZGT6, CC2530F256 and SIM900 A and the Software of intelligent interactive terminal which the interface is based on em Win GUI. The hardware and software of intelligent switch/socket have been designed. Moreover, the intelligent mobile phone APP has been set up which is based on Android system and SQLite data base. To actualize the communication between intelligent mobile phone and intelligent interactive terminal the VPS has been devised under LAMP technology(Linux+Apache+Mysql+PHP).At last, the basic principle of the genetic algorithm has been analyzed. And the processing flow chart of the genetic algorithm has been presented. An electric programming model has been established separately to reduce the electrical fee for clients under the time-of-use price and real time price. An intelligent electrical optimization algorithm was presented base on the time-of-use price and real time price separately allowing initial working time set as vari able. The validity of the intelligent electrical optimization algorithm has been validated through the MATLAB simulation.
