Marcelo de Castro Fernandes obtained his B.Sc degree in electric power engineering at Federal University of Juiz de Fora, MG, Brazil in 2017. He is currently pursuing his Ph.D. degree in electric power engineering at Rensselaer Polytechnic Institute, Troy, NY, USA. His currently interests are modeling and simulation of power systems.

Abstract:

Current power system modeling and simulation methods require analysts to study power system behavior in different modeling tools. Phasor-based models are usually the de facto standard adopted to model and simulate transient stability phenomena in transmission or distribution grids. The former is normally represented in its positive-sequence equivalent circuit while three-phase phasors are usually chosen to model the latter. In addition to that, power electronic devices are usually represented using another modeling paradigm. With the ongoing large deployment of power electronic devices in the power grid, interactions between the transmission, distribution and power-electronic interfaced devices needs to be studied. To facilitate analysis it might be advantageous to create a framework that can be used for studying heterogeneous model compositions, allowing to perform computations using the preferred model representation of each part of the power system at the same time. This project addresses this problem by proposing an integrated modeling framework to unify, at the equation level, transmission and distribution networks, and power electronic-based devices. The proposed framework is based on modeling interfaces that can be used for coalesced modeling and simulation of the different power system and component representations. A small power grid is modeled as a using this heterogeneous composition approach in order to show the benefits of the proposed framework. Linear analysis is conducted for control design purposes and simulation results are provided.
