| Summary: | The home energy management system (HEMS) can effectively participate in
price-based demand response programs, significantly reducing electricity
costs by optimizing the usage times of shift-able household appliances such
as washing machines, dishwashers, and others. However, this optimization may
compromise the comfort of the residents. In this paper, a discomfort index
is proposed based on the time intervals between the start and end of the
operation periods of these shift-able appliances relative to their
residents' preferred usage times. The problem of optimal scheduling for
these appliances is then modeled as an optimization problem aimed at
minimizing the weighted sum of the daily household electricity bill and the
discomfort index. A constraint is imposed to restrict the discomfort index
to a maximum allowable level. This optimization problem is solved using a
simulated annealing algorithm across various scenarios with different
maximum allowable values for the discomfort index. The simulation results
indicate that, among the optimal schedules across the scenarios, the most
cost-effective demand response schedule can be identified based on the
marginal reductions in the daily household electricity bill. This approach
ensures substantial decreases in electricity expenses while avoiding
unnecessary increases in the discomfort index. |
