Observing a power system in an exceptional manner is rather important for system design. Phasor Measurement Unit (PMU) devices are modern meters installed in the power systems to monitor and control the systems. In this study, Depth First Search Method (DFS), Graph Theoretic Procedure (GTh), Simulated Annealing Method (SA), and Modified Simulated Annealing Method (MSA) were used to determine the optimal PMU layout points. The limitation of the observability of the whole system was also considered in the calculations. The MSA method has been proposed as an alternative solution method for the optimal number of PMUs (OPP). The MSA method has been applied to Türkiye 400 kV Interconnected Power System in which an OPP study has not been applied before. The reliability of the method was tested by comparing the results with that of the IEEE 14-bus testing system. Thus, the number of PMUs for the Türkiye 400 kV Power System and the information on which buses these PMUs should be placed were identified. Among the applied methods, MSA Method yielded the best results. The locations of these devices have also been determined which is introduced as an alternative solution.
