Modelling, Analysis and Experimental Validation of Clock Drift Effects in Low-Inertia Power Systems [PDF]
, 2016 Clock drift in digital controllers is of great relevance in many applications. Since almost all real clocks exhibit drifts, this applies in particular to networks composed of several individual units, each of which being operated with its individual ...

Performance evaluation of secondary control policies with respect to digital communications properties in inverter-based islanded microgrids [PDF]
, 2016 A key challenge for inverted-based microgrids working in islanded mode is to maintain their own frequency and voltage to a certain reference values while regulating the active and reactive power among distributed generators and loads.

Bounds and Estimates for the Response to Correlated Fluctuations in Asymmetric Complex Networks
, 2021 We study the spreading of correlated fluctuations through networks with asymmetric and weighted coupling. This can be found in many real systems such as renewable power grids. These systems have so far only been studied numerically.

Transient Safety Filter Design for Grid-Forming Inverters [PDF]
2020 American Control Conference (ACC), 2020 Unlike conventional generators, inverter-based generation do not possess any rotational inertia. While grid-forming inverters can synthesize small (virtual) inertia via advanced feedback control loops, additional control mechanisms are needed to ensure safety and security of the power grid during transients.

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells
Molecular Oncology, EarlyView.We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Efficient Control of Active Transformers for Increasing the PV Hosting Capacity of LV Grids [PDF]
, 2016 The increased penetration of grid-connected photovoltaic (PV) systems in low-voltage (LV) grids creates concerns about overvoltage in these grids. The proposed methods to prevent overvoltage, such as reactive power absorption by PV inverters and active ...
