Magnetic and thermodynamic studies on the distorted kagome magnet Pr$_3$BWO$_9$
We report specific heat, ac/dc magnetic susceptibility as well as static and pulsed field magnetization studies on the distorted kagome magnet Pr$_3$BWO$_9$ down to 0.4~K and up to high magnetic fields. The low-temperature thermodynamic properties are found to be governed by an electronic quasi-doublet ground state; the energy splitting of which amounts to $Δ_1\simeq 18$ K and exhibits a quadratic field dependence with $g_\mathrm{eff} = 2.6$. Fitting of the specific heat data implies that the …

Nonlinear Optimal Control of DC Microgrids with Safety and Stability Guarantees
A DC microgrid is a promising alternative to the traditional AC power grid, since it can efficiently integrate distributed and renewable energy resources. However, as an emerging framework, it lacks the rigorous theoretical guarantees of its AC counterpart. In particular, safe stabilization of the DC microgrid has been a non-trivial task in power electronics. To address that, we take a control theoretic perspective in designing the feedback controller with provable guarantees. We present a syst…

@… hello! What plays as frequency source in your power backup setup with the battery of you EV as primary energy source?
I'm no electrician. From my understanding we have something like diesel generator that does not work in sync with the grid, and DC/AC converters that we want to be able to run in sync with the grid and off the grid. And as far a…

Sensitivity of DC Network Representation for GIC Analysis
Geomagnetic disturbances are a threat to the reliability and security of our national critical energy infrastructures. These events specifically result in geomagnetically induced currents, which can cause damage to transformers due to magnetic saturation. In order to mitigate these effects, blocker devices must be placed in optimal locations. Finding this placement requires a dc representation of the ac transmission lines, which this paper discusses. Different decisions in this process, includi…
