Alavi, F. (author), van de Wouw, N. (author), De Schutter, B.H.K. (author)Recently, the idea of using fuel cell vehicles as the future way of producing electricity has emerged. A fuel cell car has all the necessary devices on board to convert the chemical energy of hydrogen into electricity. This paper considers a scenario where a parking lot for fuel cell cars acts as a virtual power plant. In order to describe the...conference paper 2016

Liu, Zhihao (author), Shekhar, A. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)This paper provides an empirical study on series arc behavior in low voltage dc microgrids. The response of an R-L-C dc microgrid abstraction towards series arcs is studied experimentally for varying grid inductance, dc voltages, load capacitances and load currents. In order to account for the stochastic nature of arcs, experiments are...conference paper 2017

Caquilpan, V. (author), Sáez, Doris (author), Hernández, Roberto (author), Llanos, Jacqueline (author), Roje, T. (author), Nunez, Alfredo (author)Microgrids are suitable electrical solutions for providing energy in rural zones. However, it is challenging to propose in advance a good design of the microgrid because the electrical load is difficult to estimate due to its highly dependence of the residential consumption. In this paper, a novel estimation methodology for the residential load...conference paper 2017

(author)The traditional ac power system is challenged by the increased amount of distributed energy resources. Enormous changes and investments are necessary in order to achieve an ac smart grid capable of coping with the challenges introduced. In dc, solutions seem to be more straightforward since most of the distributed energy sources and most of the...conference paper 2015
