Short-circuit Calculations in Hybrid AC/DC Microgrids
2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS), 2022 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 ...
