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 ...

Decentralized State Estimation for Hybrid AC/DC Microgrids
IEEE Systems Journal, 2018 This paper presents a decentralized state estimation (SE) for the newly emerging hybrid ac/dc microgrid. The microgrid consists of an ac and a dc network which are connected via the interlinking ac/dc converter. The proposed SE is able to estimate the state variables of both networks in a decentralized way that the estimation is separately conducted ...

Optimal Configuration of Isolated Hybrid AC/DC Microgrids
IEEE Transactions on Smart Grid, 2019 This paper proposes a model for planning isolated microgrids. The goal of the proposed model is to minimize the investment, operational, and total costs of an isolated microgrid through the full identification of the system configuration. The model designates the optimal type of microgrid, i.e., ac, dc, or hybrid ac/dc, and the optimal sizing of both ...
