A Generalized and Mode-Adaptive Approach to the Power Flow Analysis of the Isolated Hybrid AC/DC Microgrids

Energies, 2019
Hybrid AC/DC microgrids (HMG) are emerging as an attracting method for integrating AC/DC distributed energy resources (DERs). In the isolated hybrid AC/DC microgrid (IHMG), the key problem is how to balance power variation and regulate voltage and ...

Primary results from MATCH: A randomised controlled trial in primary aldosteronism [PDF]

Endocrine Abstracts, 2021
Abstract Primary aldosteronism (PA) is now considered the sole, often curable, cause of hypertension in 5-10% of patients. Yet there has been only one RCT, and practice has changed little since the advent of CT scanning. Adrenal vein sampling (AVS) and adrenalectomy remain the standard, invasive interventions, leading to a 50% reduction ...

Equivalence of Primary Control Strategies for AC and DC Microgrids

Energies, 2017
Microgrid frequency and voltage regulation is a challenging task, as classical generators with rotational inertia are usually replaced by converter-interfaced systems that inherently do not provide any inertial response.
