An Improved Optimal Algorithm of N-1 PMU Location

Abstract:

PMU has been widely used in the power system state estimation, dynamic monitoring, and stability control. To achieve system completely observable and a certain degree of reliability, we need to set N-1 redundancy for PMU in the system. LR is a traditional method solving the N-1 best location problem. However, it can't meet the need of economical efficiency due to its oversimplified computation. This article make the biggest intersection between the solution from which that won't set redundancy and that from the LR^[ method. On the basis of the intersection result, several iteration is needed to get the appreciate result which would lead the least cost.
