摘　　要：为实现能量高质量、高效率的利用,同时提高系统供能可靠性,针对含高比例的可再生能源的区域综合能源系统,引入“㶲”的概念,提出了一种计及㶲效率和多重不确定性的双层优化方法。首先,建立了区域综合能源系统的多能耦合模型,进行㶲分析和多重不确定性分析,并且针对风光不确定性、负荷和能源价格波动的不同特点,分别采取多场景随机规划和区间优化的方法进行处理。然后,建立了上层以㶲效率和经济性为优化目标,下层以运行成本最低为优化目标,兼顾系统容量规划和调度运行的双层协同优化模型。最后,选取某园区进行算例分析,验证了所提方法的有效性,与其他不确定因素相比,电负荷的波动对系统的经济和㶲效率影响更大。In order to realize high quality and efficiency utilization of energy while improving the reliability of system energy supply,the concept of exergy is introduced into regional integrated energy system containing a high proportion of renewable energy,and a two-layer optimization method is proposed considering exergy efficiency and multiple uncertainties.Firstly,a multi-energy coupling model of regional integrated energy system is established for exergy and multi-uncertainties analysis.Multi-scene random planning and range optimization methods are adopted to deal with exergy for different characteristics of solar and wind power uncertainty,along with load and energy price fluctuations.Then,a two-layer collaborative optimization model balances system capacity planning and scheduling operations is constructed,with both exergy efficiency and economy as the optimization goal in the upper layer,and the lowest operating cost as the optimization goal in the lower layer.Finally,an industrial park is selected for example analysis to verify the effectiveness of the proposed method in this paper.Compared with other uncertain factors,the fluctuation of electrical load has a greater impact on the economy and exergy efficiency of the system.
