Abstract

In this paper, a novel intervals-based distribution short-circuit calculation algorithm is proposed. In distribution networks, there are various renewable energy-based generators (solar panels, wind generators, small hydro turbines, etc.), as well as loads with uncertain generation and consumption. Therefore, short-circuit calculation has to consider all these uncertainties. The algorithm proposed in this paper deals with above-mentioned uncertainties, as well as correlations among them. Algorithm testing is performed on two test examples of distribution networks, 6-bus and 1003-bus, for the verification of its robustness and efficiency on real-life, large-scale systems. The results demonstrate that the proposed algorithm provides highly accurate results and that it is able to solve real-life short-circuit problems with a higher precision than the traditional deterministic short-circuit calculation algorithms.

In the 6-bus test example, line’s shunt admittances are neglected due to the simplicity of the example. The proposed algorithm dealing with line’s shunt admittances and 1003-bus real-world test example has line’s shunt admittances.
