Article history: Received: 06 August, 2020 Accepted: 11 November, 2020 Online: 14 December, 2020 Phasor Measurement Unit (PMU) is an integral device for tracking, protection, and regulation of the power network. PMU gives synchronised calculations of actual-time data for voltage phasor, current phasor, and the frequency. Placing PMU in every node to observe the power network is not realistic from an economic standpoint and even for big data management. Thus, raising the number of PMUs in the node network to achieve optimum monitoring of the power network is a mandatory issue. In tracking the problem of optimal PMU placement, various methods have been proposed by various researchers in recent times. To facilitate understanding among the various approaches, this study classified the existing methods into two headings; heuristic and mathematical(conventional)methods. The study discusses the different existing optimisation approaches used to solve the optimal PMU placement problems. The benefits, as well as the drawbacks of each approach, is thoroughly examined and wind up the discussion that the heuristic approach is a fast knowledge-based methodology, which was used as the optimization solver for the IEEE 14, 30 and Nigeria national grid 28 and 52 bus system.
