Economic Dispatch of CHP System Considering Thermal Load Demand Side Management

In order to solve the problem of day-ahead scheduling of combined heating and power (CHP) system, Mixed-integer Programming (MIP) method is used to solve the problem of micro-grid economic scheduling with CHP system. First, the mathematical model of Micro Turbine (MT), the core equipment in CHP will be established, whose nonlinear model will be transformed into a linearized model according to its power-efficiency characteristic. The feasibility of the linearized model in practical application will be verified in the example. Besides, the linear model of other equipment and thermal load demand management in CHP will be established, the MIP will be used to solve the problem.
