Abstract The Phasor Measurement Unit (PMU) is a device that is employed to detect the voltage and current waveform that is synchronised with a clocking signal obtained continuously from the global positioning system (GPS). Integrating with the GPS receiver, the base station is able to receive the synchronous data from each PMU in real time. This thesis presents novel optimal placement approaches of PMU for applications such as state estimation and fault detection. In this thesis, the PMU placement is realised based on two hybrid algorithms namely Approximation Algorithm and Global Optimization Algorithm. The proposed algorithms will ensure optimum PMU placement with full network observability under different contingency conditions. The IEEE 14, 24, 30, 57 and the New England 39 standard test systems will be used to exam the proposed algorithm adequately and the result will be compared to existing methods. In this thesis, we 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, the comparison between the proposed methods to the existing methods show that the proposed hybrid approaches achieve higher System Observability Redundancy Index (SORI) which will in turn improve the reliability and stability of power transmission.
