Smart home energy management system - a review

Smart grid is providing new opportunities and techniques for supplying high energy demand of the ever growing energy industry. One-third of the total energy demand comes from the residential sector. A new frontier in this field is the Energy Management Systems being designed for the futuristic smart homes. A smart home is a home that shall be able to decide, control and optimize the operation of its equipments, on its own with minimal interference from its master, a human. One of the major factors for the successful development of a smart home is its ability to manage the energy resources including generation and storage. The recent smart home energy management publications have been reviewed in detail in this paper. The paper also elaborates on different demand response strategies used and the various equipments considered along with renewable energy generation and plug in electric vehicles (EV) employed in smart home energy management process. The literature is categorized based on various factors like tariff, storage, trading, monitoring, etc. affecting the performance of a smart home. These factors are mentioned, discussed and analysed in depth. Objective functions, constraints and communication models involved in smart home energy management models are also surveyed.
