TOU-based optimal energy management for smart home

摘要

This paper studies a smart home energy management system (SHEMS) based on time-of-use pricing (TOU). Different kinds of appliances and multiple energy sources are coordinated for economic benefits considering users' experience. Models are improved and the value of stored energy is considered. Simulation results indicates that more than 31% payments saving can be obtained, including non-price profits and price profits. Furthermore, the operational characteristic of appliances is analyzed, and the benefits of SHEMS in energy saving and emission reduction is evaluated. This paper also studies the effects to grid and the impacts of price difference between peak and off-peak.
