“…In [15], the author shows that the equations of the IEC 61660 standard, originally for low-voltage (LV) systems, can also be applied to medium voltage (MV) DC networks and discusses some limitations of the standard. In [16], HVDC systems in short-circuit conditions are studied in the case of dual inverters with dual DC-link; however, the authors, although providing an interesting description of the control system, do not consider these devices in a more general methodology for calculating DC short-circuit currents. The research work in [17] proposes a fault current calculation method for DC railways.…”

In this paper, the issues related to short-circuit calculations in hybrid AC/DC microgrids are discussed. The reference standard for short-current calculations in DC systems is the IEC 61660, which provides a mathematical formulation of the problem. The standard only includes radial DC grids and does not consider a more complex system, such as meshed DC systems or a hybrid AC/DC microgrid. This paper proposes a generalized approach that can be used independently of the characteristics of the hybrid system. The proposed approach is applied to four test microgrids with different distributed sources and number of nodes and the results are compared with those obtained simulating the same grids with Neplan 360 ® .
