Design And Implementation Of Home Energy Management System Based On NDN

With the development of smart grid,more and more household devices become intelligent.This intelligence is mainly reflected in the equipment can access the network,through the network query equipment running state and energy consumption state,and can send commands to the device remotely through the network to control the switching state of the device.With the diversification of smart home appliances,different equipment providers provide different equipment management systems,and a management system can only manage the corresponding smart devices,which brings difficulties for the unified and effective management of intelligent power equipment.This paper presents the design and implementation of a home energy management system based on NDN network.Project proposes a design and implementation of home energy management system based on NDN network,according to the application scenarios of home energy management,developed a system of naming rules based on NDN network,based on the unified naming rules,through the interaction of interest packet and data packet in NDN network,data acquisition of equipment energy consumption,scheduling control of equipment and data communication between equipment and sensor device are realized in home environment.Because the device adopts a unified naming rule,it is possible to manage all the devices effectively and uniformly through a single system.The device will automatically send data naming to the network at the point of accessing network,data acquisition module of the system according to the naming conventions,sends the corresponding named interest packet to the network to fetch energy consumption data.This mechanism can simplify the process of user manual configuration,in order to simplify the operation of users.In the project,the time tariff is used as the background,and the historical electricity price information obtained from the PJM website is crawled through simple web crawler to build the historical electricity price information database,and in consider of the working pattern of electrical equipment and the demand which the equipment provided,dividing the equipment in different category.On the base of history power price database,using ARIMA model to predict the time-of-use price for the next day,and use SLTM network model to predict the power load.System will schedule the equipment on the base of the predicted time-of-user power price and power load,sending different type of control command to the equipment to manage the equipment effectively.The project describes the design and implementation of the system from the point of naming,data acquisition,communication mode,power price prediction and load forecasting,and implements the communication between the system and the device based on the publish and subscribe mechanism.The home energy management system based on NDN using NDN network to design and implement it,improving the usability and flexibility of the system.Because using data naming instead of IP address to route and forward,eliminating the configuration process of assigning IP address to equipment and removing the process of establishing the unique correspondence between device IP address and equipment,the complexity of the system is reduced and the effect caused by network broken or power broken in the family is alleviated.The accuracy of equipment energy consumption data monitoring has been improved,using the scheduling strategy of time sharing price and load charge to reduce unnecessary power expenditure and balance the load of power grid...
