Abstract Generally, the observation of power system is carried out with minimum region unit for the optimal PMUs placement of the Smart power grid system. In world level, the power system of electrical is the major system and the power loss is the key issues in the transmission line. In order to have an efficient process with the optimal approach, GA based Enhanced Harmony and Binary Search Algorithm (GA-EHBSA) is implemented with the optimization of Improved Imperialistic Competitive (IIC) approach for complete power network observability of PMU optimal placement. The combined process is defined as Enhanced GHB-IC. It utilized with the improvement to have least PMU placement and better optimization approach for finding the optimal location. Also, it provides improvement in redundancy index, cost function and less power loss with efficient optimization. However, the process of placement and connection of the buses is considered at various places with the same cost of installation. It provides significant improvement in the profile of voltage and optimal structure for efficient optimal system. The simulation results are evaluated and compared with existing algorithm to show the efficient process of optimal PMUs placement with better optimization, minimum cost and redundancy than the existing.
