A Multi-Objective Home Energy Management System based on Non-Intrusive Load Monitoring and Heat Pump Control

Grid modernization and digitalization gradually alter the traditional operation of power systems. Demand side management has attained significant attention and the deployment of smart meters creates opportunities for new data-driven services. Towards this direction, home energy management systems (HEMS) can play a pivotal role by enabling residential demand response applications. This paper introduces a HEMS aiming at low energy cost, improved thermal comfort and scheduling of appliance operation according to end-user habits. To this end, a multi-objective optimization problem is formulated by employing a non-intrusive load monitoring mechanism and a control scheme for heat pumps. The conducted analysis investigates the effect of each objective on the overall system performance under different dynamic tariff schemes.
