摘要

系统状态的连续估计是电力系统正常运行、控制和保护的必要条件。本文介绍了将相量测量单元(PMU)测量与传统的SCADA测量相结合的IEEE 14总线系统状态估计改进的观察。首先，使用整数线性规划(ILP)优化技术确定了该测试用例完全可观察性的PMU需求的最优数量。然后，检查了PMU需求的不同组合。最后选取了4种情况，将PMU测量与传统测量相结合。最后，通过图形化表示，观察到这些情况下状态估计的改进。

Hybrid State Estimation for Diverse Combination of PMU Measurements

Continuous estimation of system states is mandatory for proper operation, control and protection of power system. This paper presents an observation of state estimation improvements for IEEE 14 bus system incorporating the Phasor Measurement Unit (PMU) measurements with traditional SCADA measurements. Initially, the optimal number of PMU requirement for complete observability of this test case is identified using the Integer Linear Programming (ILP) optimization technique. Then, the diverse combinations of the PMU requirement are checked. Incorporation of PMU measurements with traditional measurements for finally selected 4 cases are done. Eventually, the improvement of state estimation is observed for those cases by a graphical representation.
