A computational framework for risk-based power system operations under uncertainty. Part II: Case studies

With larger penetrations of wind power, the uncertainty increases in power systems operations. The wind power forecast errors must be accounted for by adapting existing operating tools or designing new ones. A switch from the deterministic framework used today to a probabilistic one has been advocated. This two-part paper presents a framework for risk-based operations of power systems. This framew

Kundval för äldre och funktionshindrade i Norden. Konsumentperspektivet

Kundval för äldre och personer med funktionshinder diskuteras i de nor-diska länderna och i vissa fall har det också införts. Kundval i handikapp-omsorgen förekommer då personer med funktionshinder väljer sin per-sonliga assistent. I äldreomsorgen finns det system där den äldre efter ett biståndsbeslut kan få välja vem som ska utföra vissa insatser. Några svenska kommuner var pionjärer i början av

On the evolutionary origin of declarative pointing

Imperative and declarative pointing are distinct kinds of communicative acts that rely on different cognitive capacities in the speakers. Declarative pointing is an important precursor to language, seen from both an evolutionary and a developmental perspective. Declarative pointing is functionally independent of affective intersubjectivity, yet it is intimately related to it in development. It is

Modeling, Calibration and Control of a Paper Machine Dryer Section

Following increased efforts during the last decade to formulate mathematical models for the paper drying process, this paper presents a Modelica library, DryLib, which enables users to rapidly develop complex models of paper machine dryer sections. In addition, parameter optimization, model reduction and moisture control by means of Non-Linear Model Predictive Control is treated. These application

A Power Market Forward Curve with Hydrology Dependence - An Approach based on Artificial Neural Networks

This paper develops an hourly forward curve for power markets where the intra-day and intra-week shapes (profiles) depend on the level of the hydrological balance. The shaping model is based on a feed-forward Artificial Neural Network (ANN), which is trained on a historical data set of hourly electricity spot prices from the Nord Pool market and weekly measurements of the Nordic hydrological balan
