Optimal Dispatching for Regional Integrated Electric and Heating Systems Considering Aggregation and Transaction of Generation-Grid-Load-Storage

源网荷储资源的协调利用,是推动区域电热综合能源系统(regional integrated electric and heating system,RIEHS)高效运行的重要手段。提出了一种考虑源网荷储聚合交易的RIEHS优化调度方法。首先,构建了RIEHS的调度框架,设计了考虑源网荷储聚合交易的RIEHS调度组织流程;其次,建立了RIEHS两阶段优化调度模型,第一阶段为虚拟电厂(virtual power plant,VPP)对源网荷储资源的聚合交易优化,第二阶段为基于源网荷储交易结果的RIEHS调度优化;最后,基于改进的IEEE 33节点配电系统和32节点巴厘岛配热系统,构建了包含3个虚拟电厂的RIEHS进行算例分析,结果表明所提方法能够通过交易手段挖掘用户侧资源的响应潜力,提高虚拟电厂的运营收益和系统运行的经济性,验证了调度方法的有效性。

The coordinated utilization of the resources of generation-grid-load-storage is an important means to promote the efficient operation of the regional integrated electric and heating system(RIEHS).This paper proposes an optimal dispatching method for RIEHS considering aggregation and transaction of generation-grid-load-storage.Firstly,the RIEHS dispatching framework is constructed,and the RIEHS dispatching organization process considering aggregation and transaction of generationgrid-load-storage is designed.Secondly,a two-stage optimization dispatching model of RIEHS is established.The first stage is the optimization of the aggregation and transaction of the resources of generation-grid-load-storage by the virtual power plant.The second stage is RIEHS dispatching optimization based on the transaction results of the resources of generation-grid-load-storage.Finally,based on the improved IEEE 33-node power distribution system and the 32-node Bali heating system,a RIEHS with three virtual power plants is constructed for simulation and analysis.The results show that the method proposed in the paper taps the response potential of user-side resources through transaction means,improves the operating income of virtual power plants and the economy of system operation.The effectiveness of the dispatching method has been verified.
