A Thermoelectric Coordinated Dispatch Method for Heat Power Units Considering the Temperature Response of Heat Users

In addressing the issue of thermoelectric coordinated dispatch for heat power units during the heating seasons, this paper first reviews the structure of the district heating system. Based on its characteristics, principles for constructing a simplified model of the district heating system are proposed, along with a specific transfer function form of the simplified model. Using the Simulink simulation results of a heating system, a simplified transfer function for the heat users’ temperature response is presented, and the parameter fitting method is given. Then, the thermoelectric coordinated dispatch strategy for heat power units is explained, and the optimization objectives are provided. Finally, the accuracy of the proposed model and calculation method is verified through time-series production simulation and Simulink simulation.
