摘　　要：为满足大区互联电网运行分析与调度控制对电网模型精细化的要求,提出一种多区域互联电网模型实时拼接、形成全局电网模型的方案。基于带约束状态估计的多区域电网拼接算法,将模型在线拼接问题转化为一个带边界等式约束的状态估计问题,并应用现代内点法进行求解。介绍了测试算例与实际应用结果。In order to meet the demand of network model refinement for the regional interconnected power grid opera- tion analysis and dispatching control, a scheme is required to form a global grid model by real-time multi-region inter- connected network model splicing. This paper presents an algorithm for multi-region network model splicing based on constrained state estimation, whereby online model splicing is converted into state estimation mode]~ with boundary e- quality constraints and modern interior-point method is applied to solve the problem. Results of simulation on testing system and actual application show that the method can efficiently achieve online splicing of region power grid with different control centers.
