Optimizing Phasor Measurement Unit Placement Approach for Enhanced System Observability

This paper presents an Integer linear programming (ILP) model to optimize the integration of PMUs. The proposed method addresses two important goals reducing the number of PMUs required for a complete system overview and reducing redundancy measurement. By increasing system reliability through strategic redundancy, this method ensures robust performance under adverse conditions. The results obtained, in terms of the System Observability Redundancy Index (SORI), the proposed method is easy to implement and provides optimal PMU placement locations for efficient monitoring of new methods, especially for IEEE-14. IEEE-30, IEEE-57, and IEEE-118 test systems.
