摘要：
A dispatch method with synergy and interaction between integrated energy station and users is put forward to solve the problems that the thermal storage characteristics of building envelopes and subsidy mechanisms of demand response for users are not considered during the operation and dispatch of integrated energy station. Firstly, an elaborate building virtual storage model is established using the indoor air and building envelope as the main parts of heat transfer subject through comprehensive consideration of influences of indoor and outdoor disturbances on thermal process. Secondly, the equipment composition structure of typical energy station with supply of cooling, heating and power systems and a multi-agent interactive transaction relationship among external power companies, integrated energy station and users are established, and a demand response mechanism based on tiered subsidy is proposed. Thirdly, a day-ahead economic dispatch model of energy station is established by taking the maximum operation earnings of energy station as the target, containing external power purchase expenses, incomes through selling power to users, subsidies and start-up/shut-down costs, and the flexible comfort level of users as constraints. The CPLEX solver is adopted to solve the problems. Finally, the practicability and effectiveness of the proposed model and method are verified through examples. © 2020 Automation of Electric Power Systems Press.
