Fundamental Problems and Research Framework for Assessment and Optimization of the Functional Regulation Capacity of the Regional Integrated Energy System Under the Aggregation of Diversified and Flexible Resources

区域综合能源系统(regional integrated energy system,RIES)通过对多元灵活资源的整合与协调,在本地多能源供需平衡的基础上优化可调节能力,进而通过共享可调节量实现跨区域能量互济,有望提升能源利用效率,在深入挖掘海量用户可调节潜力,充分发挥系统灵活性价值方面发挥着重要作用。该文首先系统分析多元灵活资源聚合下构建RIES的驱动力和瓶颈,对现有研究概况进行综述。基于当前研究路径,从RIES主动调节能力时空动态演变规律深度挖掘、复杂非线性动态RIES主动调节能力优化、多RIES集群分布式最优协调3个方面,分析RIES研究过程中的关键问题。在此基础上,从RIES“主动调节能力评估、自治协调优化、集群协同控制”3个共同影响系统经济稳定运行的重点问题提出多元灵活资源聚合下RIES的研究架构,并对关键研究内容进行分析和阐述。

The regional integrated energy system(RIES)integrates and coordinates diversified and flexible resources to maintain local multi-energy supply-demand balance,optimize the adjustable capacity,realize cross-regional energy complementarity,and improve energy utilization efficiency by sharing the adjustable capacity.It plays an essential role in deeply mining the adjustable potential of massive users and giving full play to the value of system flexibility.First,this paper analyzes the driving force and barriers to building RIES under the aggregation of diversified and flexible resources and systematically reviews the existing research.Then,based on the current research clues,the critical problems of the RIES are analyzed from three aspects:in-depth mining of the spatio-temporal dynamic evolution of the functional regulation capacity of the RIES,optimization of the functional regulation capacity of complex nonlinear dynamic RIES,and optimal coordination of multiple RIES clusters.On this basis,the research framework of the RIES under the aggregation of diversified and flexible resources is proposed from three key issues that jointly affect the stable and economical operation,namely,the assessment of the functional regulation capability,the autonomous coordination and optimization,and the collaborative cluster control of the RIES.Finally,the critical research contents are analyzed and elaborated.
