Optimal Power Dispatch and Load Scheduling For Multi-Energy Community With Fuel Cell Combined Heat and Power

This paper proposes an optimization scheme of the power dispatch and load scheduling for multi-energy community with fuel cell (FC) combined heat and power. In the community, every household is connected to the shared power grid, photovoltaic (PV) system, FC and boiler. The electrical appliances in every household are powered by the electricity from the power grid, PV system and FC. The thermal energy from the FC and boiler is used for home heating in every household. The proposed optimization scheme optimizes the electrical appliance scheduling and indoor temperature of every household, as well as the electrical and thermal power dispatch of the shared power grid, PV system, FC and boiler. To solve the proposed optimization using mixed integer linear programming, piecewise linear approximation is applied to the non-linear relationships between natural gas consumption and electrical power of FC, and that between the thermal power and electrical power of FC.
