Optimal Scheduling of an Isolated Wind-Diesel-Energy Storage System Considering Fast Frequency Response and Forecast Error [PDF]

Energies, 2019
Nowadays, the hybrid wind–diesel system is widely used on small islands. However, the operation of these systems faces a major challenge in frequency control due to their small inertia.

Electric vehicle charging as a source of nordic fast frequency reserve—proof of concept [PDF]

IET Generation, Transmission & Distribution
Demand‐side flexibility or demand response (DR) has long been recognized as a potential source of balancing capacity. The charging of electric vehicles (EVs) is a known source of flexible capacity, and the vast amount of charging capacity available can ...

Co-Optimization of Ancillary Services Providing Primary Frequency Control in the Day-Ahead Market [PDF]

IEEE Access
Large-scale integration of inverter-based resources (IBRs) challenges primary frequency control because IBRs don’t typically respond to frequency fluctuations, which is partially due to a lack of financial incentives.

Multidimensional Measurements of Dysarthria in Myotonic Dystrophy Type 1. [PDF]

Int J Lang Commun Disord
ABSTRACT Background Myotonic dystrophy type 1 (DM1) is a heterogeneous neuromuscular disorder characterized by progressive muscle weakness and myotonia. Dysarthria is a known symptom of DM1, but literature is lacking about the patient's own perception in relationship to dysarthria characteristics and severity.
