Fault Behavior of Power Distribution Networks with Distributed Generation and Uncertainties

Comunicació de congrés presentada a: 2020 IEEE PES Transmission & Distribution Conference & Exposition Latin America (28 setembre - 2 octubre 2020: Montevideo, Uruguay). https://www.ieee-tdla2020.org/

This paper assesses the fault behavior of power distribution networks with distributed energy resources and uncertainties related with the representation of different grid components and parameters. The algorithm is based upon an impedance representation of the grid, relying on information about the network topology and electrical parameters of the feeders. In addition, distinct types of loads and distributed energy resources are represented as non-deterministic parameters, as well as the fault impedance and fault distance parameters and errors in the phasor quantities. As an outcome, the implementation of the proposed method shall provide a comprehensive, but accurate estimation of the points of fault by considering a range of possible fault scenarios. Furthermore, the methodology is demonstrated in a small overhead distribution network simulated under different operating conditions. For a given short-circuit current, the results indicate a range of possible fault distances – and vice versa
