Main Article Content

Sobha Rani.P, et. al.


Contingency analysis is one of the tools in smart distribution management system to analyze the contingencies, associated violations of line currents, bus voltages and power flows. In this paper, distribution power flow method using superposition principle is implemented to observe the contingencies under different loading conditions. The results are analyzed by placing distributed generation sources at various buses for different loadings. Contingency ranking is evaluated based on performance indices determining line over loading and bus voltage violations. The proposed method is illustrated through simulations of loaded 33-bus radial distribution system
