This paper presents a method of mathematical technique using Joint Approximate Diagonalization of Eigen Matrices (JADE). The advantages of this method, it can predict the original analysis of source signal using limited information of the system as well as to minimize costs by reducing the number of equipment to estimate the type of load profile at certain locations. By using innovative methods based Power System Simulation (PSS™E) software, Phyton Programming, Matlab software and Microsoft Excel are implemented. The proposed technique is tested on 69 test bus system and several results such as simulation and error measures are also discussed in this paper.
