摘　　要：针对多能系统集群开展分布式交易的新形势,提出一种多能系统优化运行决策模型。多能系统参与分布式交易的背景下,其运行策略优化是融合了多能系统内部调度计划和外部市场分布式交易的协同优化。基于多能系统中各类电源、储能及能量转换设备的运行特性及多能流耦合关系分析,以多能系统综合运行成本最小为目标,考虑各类设备运行约束,建立多能系统内层资源调度优化模型,优化决策多能系统各种能源的消耗和能源间的转换关系。在此基础上,基于交替方向乘子法(ADMM),建立嵌入多能系统内部调度优化的互联多能系统集群分布式交易优化仿真模型。通过算例证明该模型可兼顾多能系统自身个体利益和集群整体利益,仿真分析多能系统集群的交易格局分布特征,决策出多能系统的优化运行策略。Pointing at the new situation of distributed transaction in multi-energy systems,an optimal operation decision model of the multi-energy system is proposed.Under the distributed transaction background,operation strategy optimization of multi-energy system is a collaborative optimization which is an integration of internal multi-resource scheduling plan and external market distributed transaction plan.Based on the operating characteristics and multi-energy flow coupling relationship of various power supplies,energy storage and energy conversion equipment in the multi-energy system analysis,with the goal of minimizing the comprehensive operating cost of the multi-energy system,considering the operating constraints of various types of equipment,this paper establishes an internal resource scheduling optimization model of multi-energy system,and optimizes the decision of the consumption of various energy sources in the multi-energy system and the conversion relationship between the energy sources.On this basis,the alternating direction multiplier method(ADMM)is used to establish an distributed transaction simulating model of interconnected multi-energy system for embedded internal scheduling of multi-energy system.The calculation example shows that the model in this paper can take into account the self-interests of each multi-energy system and the overall benefits of the cluster.The distribution characteristics of transaction pattern of multi-energy system clusters are analyzed by simulation,and the optimal operation strategy of multi-energy system is decided.
