  • In the context of smart power grids, demand-side management is a set of measures to motivate end consumers into adapting their energy demand to the available generation resources. To achieve this goal, demand-side management solutions reward flexible consumers through demand response programs. Recent trends point towards the development of home energy management systems to leverage the potential of residential consumers to contribute to demand response efforts. However, current research is still ongoing and more studies are needed on how to design demand response programs with home energy management systems that appeal to end consumers. This study addresses limitations of home energy management systems in the literature and proposes a demand-side management approach based on a bi-level optimization model. First, consumers solve a lower-level multi-objective load scheduling problem to optimize their savings and comfort. Then, demand aggregators solve an upper-level single-objective demand profile aggregation problem to optimize its peak-to-average ratio. Experiments investigate the impact of optimization methods, distributed energy resources, consumer preferences and behavioral patterns on the demand response program. Results indicate that end consumer flexibility and active consumer participation are key factors to the success of demand-side management solution.
