[0004]Most of the existing research still considers the influence of comprehensive demand-side resources on the overall energy efficiency of the system and the optimal economic operation cost, or analyzes how the demand-side resources under the condition of energy prices Response and the response behavior of each demand subject is to study the operation optimization problem of the integrated energy system under the condition of known energy prices. There is less research on the multi-energy coordinated response based on the node energy price of the integrated energy system. The multi-energy users are only energy prices. passive recipient of

Although some studies have studied the node energy price of integrated energy, they are limited to the study of node energy price, or lack the calculation of node heat price, and have not considered the impact of node energy price on the demand side of multiple types of loads in the horizontal time transfer guidance
