Increasing the use of solar photovoltaic (PV) generation in order to decarbonize electric energy system results many challenges. Overvoltage is one most common problems distribution systems with high penetration PV. Utilizing demand-side resources such as residential demand response (RDR) have potential alleviate this problem. To increase PV hosting capacity, we propose an RDR based load-shifti...

The insufficient power system flexibility and transmission congestion are two fundamental reasons for wind curtailment. As the scale of in is growing rapidly, factors curtailment events coexist have a certain coupling relationship. configuration energy storage can not only increase but also alleviate congestion. Therefore, joint planning grid that takes into account great significance to solve ...

To decrease wind curtailment rate and increase power accommodation, purchase area should purchase. However, the current electricity price of is higher than that thermal power, which makes accommodation difficult to quantify. It not practical optimize these two objectives cost. Based on this contradiction, paper describes contradiction by constructing a multi-objective optimization model (MOOM) ...

The rising share of Variable Renewable Energy Sources (VRES) in the electricity generation mix leads to new challenges for whole energy system. It especially raises technological issues handle variability and match load with supply at all times. This study introduces a methodology quantify relevance different storage technologies, based on time scale analysis. additionally provides an understan...

Abstract In recent years, renewable generation, especially wind, and solar have become one of the major generation resources in electrical power systems. Due to non-dispatchable feature curtailment occurs when rest system is not able accommodate maximum output. To analyze planning stage, however, traditional studies such as production simulation method are limited identifying accurate rates sin...

Chronic sleep curtailment is a major concern for health in Western societies. Yet, research on potential consequences of long-term sleep curtailment on cognitive functions is still scarce. The present study investigated the link between chronic sleep limitation and executive functions that enable adaptation to changing environmental demands, i.e. the ability to flexibly implement task goals. To...

Sleep curtailment is becoming widespread in modern society. In parallel with this, more and more studies are dealing with the health consequences of sleep deprivation. This short review focuses on the main results of studies examining the effects of sleep and sleep deprivation on metabolism with extra emphasis on appetite regulation, and on the endocrine and immune system.

We report an outbreak of infection due to genotypically identical extended-spectrum beta-lactamase--producing Escherichia coli among patients in a liver transplantation unit. Control of the outbreak was achieved by a combination of contact isolation, feedback on hand hygiene, and gut decontamination with an orally administered fluoroquinolone. These interventions led to abrupt curtailment of th...
