摘要:
      针对综合能源站运行调度中未考虑围护结构蓄热特性以及用户需求响应补贴机制等问题,提出了一种考虑用户协同互动的综合能源站调度方法。首先,综合考虑室内外各种扰量对热过程的影响,建立了以室内空气与围护结构为传热主体的精细化建筑虚拟储能模型;其次,构建了冷热电联合供应的典型能源站设备组成结构以及其与外部能源系统、用户的多主体互动交易关系,提出了基于阶梯型补贴的需求响应机制;再次,以考虑外部购能费用、向用户的售能费用与补贴、站内设备启停和损耗成本的能源站运行收益最大为目标,以用户柔性舒适度区间等为约束,构建了能源站日前经济调度模型,并采用了CPLEX求解器求解;最后,通过算例验证了所述模型与方法的实用性和有效性。
Abstract:
      A dispatch method with synergy and interaction between integrated energy hub and users was put forward aimed at the problems of failure to consider the thermal storage characteristics of building envelopes and demand response subsidy mechanisms for users during the operation and dispatch of integrated energy hub. First of all, a building virtual storage model was established with the indoor air and building envelope as the main part of heat transfer through comprehensive consideration of influences of indoor and outdoor disturbances on thermal process; secondly, a typical equipment composition structure of integrated energy hub with supply of cooling, heating and power systems and a multi-agent interactive transaction relationship among external power companies, integrated energy hub and users were established, and a stimulating demand response mechanism based on user subsidy was put forward; thirdly, an optimized economic dispatch model of integrated energy hub was established with the maximum earnings of power station as the target, containing external power purchase expenses, incomes through selling power to users, subsidies and start-up/shut-down costs and with the flexible comfort level of users as constraints, and the CPLEX solver was adopted to solve the problems; finally, the practicability and effectiveness of the expressed model and method was verified through examples.
