Optimum Location of Phasor Measurement Units in Smart Grid Environment Using Binary Integer Linear Programming

In this thesis optimal placement of phasor measurement unit (PMU) is approached for applications such as state estimation and fault detection. In this thesis, the PMU placement is realized based on a new Binary Integer Linear Programming (BILP) approach. The proposed approach will ensure optimum PMU placement with full network observability under different contingency conditions. The IEEE 14, 30, and 57 standard test systems will be used to exam the proposed approach adequately and the result will be compared to existing methods. In this thesis, it is demonstrated that the proposed methods are very effective in determining the minimum number of PMU and the results are comparable to the best methods presented in the past literature. In addition, System Observability Redundancy Index is calculated and according to which PMUs are placed to make only the important buses of power system observable even if a contingency occurs in the system.
