Simulación de contingencias basados en flujos dinámicos de potencia para sistemas eléctricos de transmisión

Abstract

In electrical power systems, one of the challenging tasks is to preserve quality and safety, with the aim of providing continuity of electrical power to users in the event of any contingency. The contingency analysis technique is widely used to predict the effect of interruptions and thus establish the necessary actions to keep the power system safe and reliable. The actions resulting from predicting the effect of the contingency is a very laborious task, since the power system contains a large number of components. In practice, operators are responsible for determining the contingencies that will lead to inadequate operating conditions for the electrical system, the process of identifying these contingencies is known as "Selection of Contingencies", this process can be carried out through different mechanisms, being One of these is the analysis using dynamic power flows. Therefore, the present paper aims to apply the analysis of dynamic power flows to a contingency, so that the network operator can perform the actions for the power system to maintain its normal operation, for this purpose this paper shows its applicability in an example of application in the National Interconnected System of Ecuador
