In the context of the "double carbon" target, a comprehensive energy system optimization and scheduling model considering REGS and adjustable thermoelectric ratio is proposed to address the abandonment problem caused by the "heatdetermined" mode of CHP units. Firstly, we construct a model such as dry heat rock extraction cycle, and analyze the energy allocation coefficient for REGS as the source of thermoelectric adjustable mechanism; secondly, we study the coupling operation mechanism of REGS with solar thermal power plant and cogeneration unit, analyze the mechanism of coupling operation to improve thermoelectric ratio, and introduce a generalized unit thermoelectric ratio control model; thirdly, we construct an objective function with the sum of energy purchase cost, operation cost, operation and maintenance cost, wind abandonment cost and carbon tax cost; finally, the proposed model is verified to improve the system economy and wind power consumption rate and reduce carbon emission by using the actual data of a region in Northwest China.
