Problems solved by technology

[0003] However, in the current operation and calculation of combined heat and power systems, the electric energy supply is calculated through a single power system model, and the thermal energy supply is calculated through a single dynamic model of the heating system, but the independent calculation of electricity and heat energy will lead to the calculation of energy supply results Inaccurate; in addition, through some empirical supply parameters or directly, through excessive energy supply to ensure user-side demand, resulting in waste of fuel and excessive discharge of pollutants, affecting air quality and increasing carbon emissions
