Electric heating water comprehensive energy system considering demand response and stepped carbon tax

An electric heating water comprehensive energy system considering demand response and stepped carbon tax relates to the technical field of comprehensive energy system optimization, and comprises the following steps: firstly, establishing a comprehensive energy system model constructed by subsystems such as a photo-thermal power station, a CHP unit, wind power, photovoltaic and gas-fired boilers; then, through cooperative efficient utilization of a photo-thermal power generation system and a seawater desalination system, a demand response model is constructed to achieve mutual replacement between electric water and hot water, the carbon tax cost of the comprehensive energy system is improved, a stepped carbon tax cost model is constructed and introduced into the comprehensive energy system to optimize carbon emission reduction, and the energy utilization rate of the comprehensive energy system is improved. According to the optimization scheduling method, the lowest energy transportation and purchase cost, the
