Energy Management Strategy for Residential Microgrid with Photovoltaic and Controllable Thermal Loads

In this paper, an energy management strategy for residential microgrid with PV, controllable thermal loads and energy storage system is proposed. In order to realize the management and power dispatching for a microgrid, the proposal takes economic and comfort performances into account. In order to reduce the computation of management process, the energy management commands are classified and different calculation methods are adopted for different cases. By simplifying the system models and cost functions, energy management system can select the optimal power command. Finally, simulation results are presented and verify that the proposal can improve the operation performances: reducing the economic cost, avoiding large scale of power exchanged with grid and lowering the computation burden.
