Abstract
In the conventional load flow technique, it is assumed that the generator at the slack bus is used to supply the transmission losses and the change of power due to the generator outage. The assumption is not true in physical sense. This paper presents a new load flow technique that considers the governor-frequency characteristics and load-frequency characteristics and the technique is consistent with the actual power system phenomenon. This paper proposes an efficient methodology using sensitivity with the new technique for contingency analysis, which is used to calculate the line flows. Computational results of this technique applied to IEEE 14-bus system are presented.
