Abstract: Aiming at the synergy optimization problem of longitudinal transition between energy and lateral shift of energy consumption for thermoelectric coupling system in smart energy community, this paper proposes an optimization method of energy consumption considering thermoelectric coupling system of demand response through refined modeling of energy consumption for demand response on load side. Based on the analysis of the structural framework of typical thermoelectric coupling system, the energy hub（EH） equation between energy supply side, energy consumption on load side containing thermoelectric coupling system is established by the mathematical modeling of load classification and response process for energy consumption. And the quantitative description of energy conversion between load response of energy consumption and energy supply is realized. Then,the demand response degree of load for energy consumption is expressed as the participation ratio of the transformable load and the shiftable load. The optimization model of energy consumption is established with the lowest system operation cost. A model solution method with flexible scale and participation of multiple demand responses is proposed for the optimization of energy consumption.The results of experiments show that the peak of load on supply side and the total system cost can be reduced at the same time with high shiftable load participation ratio and low transformable load participation ratio, which achieves the optimal operation of the thermoelectric coupling system.
