摘　　要：园区综合能源系统运营商和用户主体之间存在复杂的利益博弈关系,因此研究如何在提高系统整体经济效益的同时平衡各方主体利益具有必要性。为此,提出一种考虑多主体利益的园区综合能源系统日前经济优化调度策略。考虑利用园区综合能源系统多能协同互补优势参与需求响应市场交易,建立两级递阶经济优化调度模型:上层是以运行利润最大为目标的运营商优化调度模型,下层是以用能成本最小为目标的用户优化响应模型;采用基于目标级联法的分布式优化算法实现上下层模型的解耦和独立并行求解。通过算例分析,验证了所提策略通过综合需求响应可实现园区供、用能侧可调资源的协同优化,并通过分布式求解使各主体经济效益均达到最优。There is a complex interest game relationship between the operators and users of the park integrated energy system(PIES),so it is necessary to study how to balance the interests of all stakeholders while improving the economic benefits of the whole system.Therefore,a day-ahead optimal economic dispatching strategy considering the interests of multiple stakeholders is proposed for the park integrated energy system.Considering the use of multi-energy cooperation advantages of the system to participate in demand response market transactions,a two-level hierarchical economic optimal scheduling model is established,in which the upper level is the optimal dispatching model of operators with the goal of maximizing operating profit,and the lower level is the optimal response model of users with the goal of minimizing energy cost.A distributed optimization algorithm based on analytical target cascading is used to decouple the upper and lower models and solve them independently and in parallel.Through the case analysis,the proposed strategy is verified to realize the collaborative optimization of the supply and demand sides through the integrated demand response,and optimize the economic benefits of each stakeholder through distributed solution.
