In a modern interconnected power system, it is challenging to estimate the amount of power delivered to loads through the transmission lines due to the individual associated generator. This study presents a mathematical approach which helps in the development of an important tool viz. power contribution coefficient, via which the share of power generated from an individual generator and delivered to the rest of the power system network has been traced efficiently. The proposed method presents a modest and spontaneous way of resolving real and reactive power flows through the transmission network due to all associated generators separately. It also gives the contribution of the individual generator to overall system losses and individual load distribution. To clarify the approach, the resolution of a sample case is provided using the proposed method. The performance of the developed technique has been investigated on IEEE 14-bus test system. To validate the method, the outcomes of the projected algorithm of the test system are compared with those obtained by using other conventional power tracing methods. Also, the execution time for different bus systems using the proposed methodology is observed to be comparatively less than other existing approaches, which justifies the fastness and robustness of the presented one.
