Optimal Scheduling of Combined Heat and Power Based Microgrid

The efficiency and economic performance of the microgrid (MG) are significantly improved by the combined heat and power (CHP) unit. In this paper, an optimal scheduling method for the CHP-based MG based on model predictive control (MPC) is proposed. Based on the energy hub (EH) model, the model of CHP-based MG was presented. An optimal scheduling model whose purpose is to minimize the total cost for CHP based microgrid was proposed in this paper then. And the MPC method was applied to the optimal scheduling model to deal with the uncertainty of renewable energy in the MG. The method is applied to a typical CHP based microgrid to verify the effectiveness.
