dc.description.abstractA power distribution network is simply an interconnection of 33/11 kV power transformers, network in-feeds, distribution station buses, and loads. The security of such a system is of great consideration in power utilities. Thus, contingency analysis is often used to determine the security of such systems. Several methods used in analyzing power system security include linear programming (LP), least squares (LS), decision trees (DTs), artificial neural networks (ANN), etc. These methods were observed from the literature to take a long computational period. Therefore, this paper presents a contingency assessment of medium voltage distribution networks using the Newton Raphson (NR) technique of NEPLAN software. The approach involves carrying out of power flow analysis of the case study network. This analysis considered four scenarios; base case, case 2, case 3, and case 4 which are respectively defined as the system operating under normal conditions, abnormal operating conditions without contingency, N-1 contingency, and N-2 contingency respectively. The results of the four cases show that contingency has negative effects on power equipment and customers. The details of these results are presented. This contingency analysis thus provides the reliability evaluation of the network while solutions to problems emanating due to contingencies are solved by utility companies for revenue improvement.
