van der Horst, Koen (author), Diab, I. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)The traction substations of urban electric transport grids are oversized and underutilized in terms of their capacity. While their over-sizing is an unfortunate waste, their under-utilization creates the major hurdle for the integration of renewables into these grids due to the lack of a base load. Therefore, integrating smart grid loads such...journal article 2023

Bauer, G.E. (author), Tang, P. (author), Elyasi, M. (author), Blanter, Y.M. (author), Van Wees, B. J. (author)We discuss spin-wave transport in anisotropic ferromagnets with an emphasis on the zeros of the band edges as a function of a magnetic field. An associated divergence of the magnon spin should be observable by enhanced magnon conductivities in nonlocal configurations, especially in two-dimensional ferromagnets.journal article 2023

Bondarenko, A.V. (author), Kounalakis, M. (author), Kusminskiy, Silvia Viola (author), Bauer, G.E. (author), Blanter, Y.M. (author)Optical photons are ideal carriers for long-distance transmission, while state-of-the-art quantum processors, such as supercon-ducting qubits, operate at microwave frequencies. An important requirement for networked quantum computation is therefore the ability to coherently convert the quantum information from microwave to optical frequencies...conference paper 2023

Liao, Jianquan (author), Zhou, Niancheng (author), Qin, Z. (author), Wang, Qianggang (author), Bauer, P. (author)The unbalanced power between positive and negative poles in a bipolar DC distribution network (DC-DN) generates an unbalanced current at the neutral line, which enlarges the power losses of the system and the voltage deviation of DC loads. An unbalanced power suppression strategy based on a series-parallel power flow controller (SP-PFC) is...journal article 2023

Diab, I. (author), Saffirio, Alice (author), Chandra Mouli, G.R. (author), Bauer, P. (author)Solar PV systems have so far been the source of choice for the sustainable supply of urban electric transport networks—like trams and trolleybus grids. However, no consensus exists yet on the placement or sizing of PV systems at the traction substations, and no method is available for easy estimation of the PV system utilization performance....journal article 2023

Wang, L. (author), Qin, Z. (author), Wu, Y. (author), Bauer, P. (author)Reinforcement of the legacy grid infrastructure will be very costly and thereby unrealistic. Consequently, weak grid connection of electric vehicle (EV) chargers will sooner or later be the case. It may however bring instability issues since the EV chargers that can work well in strong grid conditions usually do not fit the weak grid...conference paper 2023
