Today, due to the expansion of nonlinear loads, harmonic distortion has increased in power networks and has led to a decrease in power quality (PQ) in them. Regarding to the fact that utilities are responsible for supplying the quality of voltage at the points of sale of electrical energy to customer. Hence, the exact determination of the harmonic contribution of each customer in them is very important. In this paper, a new method based on the crossed frequency admittance matrix is proposed to determine the contribution of each customer on the harmonic distortion of interconnected networks. The basis of this method is the separation of linear and nonlinear load behavior and its effect on harmonic distortion in whole of network. The proposed method is tested in a 5-buses interconnected network, which results show the of the proposed method's accuracy.
Keywords: Harmonic Contribution, Power Quality, Interconnected networks, Admittance matrix
