A new accurate parameter estimation method for unbalanced three-phase system based on correlation function

This work addresses the problem of the unbalanced three-phase system accurate estimation parameter. This problem occurs in various fields of applications, among which is Smart Grid. It is well known to use the unbalanced three phase power system for modeling in smart grid applications. In this work, we propose a new analytical method in order to obtain an accurate estimation of the unbalanced three-phase system based on correlation function. The main advantages of the analytical proposed method, that it gives an exactly accurate estimation of these parameters. Computer simulations are provided in order to illustrate the good behavior of the analytical proposed method in a noiseless context. Finally, this new method is compared to other put forward in the literature which is based on Newton-Raphson scheme [1].
