Artificial Electric Field Algorithm for Optimum PMU Placement

Wide area monitoring system (WAMS) is one of the most important technologies in modern power systems which based on synchronized phasor measurement units (PMUs) to gather the synchronized time stamped measurements. There are several approaches to solve the optimal PMU placement (OPP) with various optimization algorithms. In this paper, a cost model has been proposed to provide optimal PMUs placement (OPP). The proposed model has been solved using artificial electric field algorithm (AEFA). AEFA has been implemented in MATALB programing environment, and the results demonstrate that the proposed cost model provides a realistic view of WAMS cost. Additionally, the results were compared with other related optimization algorithms which demonstrate that the AEFA is efficient to solve the OPP problem.
