On background of Energy Internet (EI) and active distribution network (ADN), a new type of smart controller based on low voltage carrier communication technique was developed, which could finish multi-interaction between the users and Power Supply Company (PSC) in aspects of energy flow and information flow, and the process was finished in distribution lines. Based on modern high precision measuring technique, the voltage and current in 220V AC lines are monitored in real time to obtain a large amount of electricity data of users, which provides sufficient data samples for smart electricity consumption mode analysis of home users, the demand side response modeling, and the work of ADN. The application research of designed smart controller on smart electricity consumption (SEC) was performed in four aspects, and it could support the "plug and play" of electrical equipment, based on the smart controller and other hardware devices and communication network, a smart home electricity management system was designed, and the smart electricity consumption mode was given and its mathematical model was built and the energy efficiency analysis and evaluation model were given. The designed smart home electricity management system could adequately take use of the home energy and photovoltaic generation, which have great significance to build Global Energy Internet in future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
