A Multi-Objective Scheduling Technique for Home Energy Management System

Scheduling the home appliances is not an easy task. In general, the householder is forced to choose between reducing his electricity bills while scarifying his discomfort or minimize his discomfort while paying more. In this paper, the user can adjust the tolerated discomfort and know in advance its correspondent of electricity daily payment. The power scheduling approach is elaborated as an optimization problem containing integer variables in case of time flexible appliances and continuous variables in case of power flexible appliances. Optimal solvers are used to generate exact solutions according to the householder predefined objectives. The simulation results demonstrate that the suggested approach can optimally schedule the home appliances according to the householder objectives: reducing the electricity payments, minimizing the discomfort, or finding a compromise between the two objectives.
