The Wave Dragon is an offshore wave energy converter of the overtopping type. It consists of two wave reflectors focusing the incoming waves towards a ramp, a reservoir for collecting the overtopping water and a number of hydro turbines for converting the pressure head into power.

The present paper investigates the introduction of pumped storage systems (PSS) in isolated power production systems with high thermoelectric production and wind energy rejection.

The impact of large penetration of wind power on the transient stability of multi-machine power systems is discussed in this paper. Variable speed wind farms with doubly fed induction generators (DFIG) are considered. A new index based on the sensitivity of the DFIG terminal voltage is used to...

Recent developments in electricity markets such as the increased deployment of variable renewable generation have prompted renewed interest over the role of energy storage. While storage technologies can in principle provide various benefits for the functioning of an electrical grid, many energy...

It is expected that the renewable share of energy generation will rise considerably in the near future. The intermittent and uncertain nature of renewable energy (RE) calls for storage and grid management technologies that can allow for increased power system flexibility. To assist policy makers...

In this work, we study the profitability of energy storage operated in the Nordic, German, and UK electricity day-ahead markets during 2006-2016. We build a linear optimization model which maximizes profits from arbitraging hourly prices and use the model output of profits and storage cycles in...

Legislative requirements are motivating vehicle manufacturers to produce innovative electric vehicle (EV), hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV) concepts. End-of-Life (EOL) for the vehicle's battery is often taken to be the battery having 80% retained capacity....

Die Energiewende in Deutschland erfordert neben neuen Übertragungsleitungen für regenerativ erzeugten Strom auch den Bau neuer Speicherkraftwerke. Für das bei Trier geplante Pumpspeicherkraftwerk Rio wurde 2012/2013 ein Raumordnungsverfahren durchgeführt. Der folgende Beitrag dokumentiert...
