Novel WSN-based residential energy management scheme in smart grid

Smart grid integrates the latest advances in information and communication technologies to contribute to a more reliable and efficient electricity system. By realizing the two-way communication between the utility and the smart meters in the houses, smart grid enables a time-of-use tariff to reduce peak load through incenting residents to adopt a more efficient usage of domestic appliances. In this paper, the candidate communication techniques and the classification of appliances are discussed. Then we proposed a WSN-Based Residential Energy Management Scheme which wirelessly connects non-urgent appliances to the smart meter through the wireless sensor networks. The structure components and the algorithm shows that the scheme can response to the resident´s command with the economically suggestion, and help them shift their non-urgent appliances to the off-peak hours. Therefore, the high peak load is alleviated, the green-house gas emission is reduced, furthermore, through the two-way communication, the utility is able to decide the optimal generation plan to satisfy resident demands, and the total utility cost can be reduced.
