Váh

The Váh (Slovak pronunciation: [ʋaːx]; German: Waag;Hungarian: Vág;Polish: Wag) is the longest river within Slovakia. Towns on the river include Liptovský Hrádok, Liptovský Mikuláš, Ružomberok, Vrútky, Žilina, Bytča, Považská Bystrica, Púchov, Ilava, Dubnica nad Váhom, Nemšová, Trenčín, Nové Mesto nad Váhom, Piešťany, Hlohovec, Sereď, Šaľa, Kolárovo and Komárno.

Geography

A left tributary of the Danube river, the Váh is 406 kilometres (252 mi) long, including its Čierny Váh branch. Its two sources, the Biely Váh (White Váh) and the Čierny Váh (Black Váh), are located in the Vysoké Tatry (High Tatras) and Nízke Tatry (Low Tatra) mountains, respectively, and it flows over northern and western Slovakia and finally feeds into the Danube near Komárno. The left tributaries are Demänovka, Revúca, Ľubochnianka, Turiec, Rajčanka and Nitra rivers, and the right tributaries are Belá, Orava, Varínka, Kysuca, Biela voda, Vlára, Dubová, Dudváh and Malý Dunaj rivers. In late medieval time it was a property of Stibor of Stiboricz and his son Stibor of Beckov of the Clan of Ostoja, later passing to Maurice Benyovszky as a gift of Maria Theresa.

Vehicle-to-grid

Vehicle-to-grid (V2G) describes a system in which plug-in electric vehicles, such as electric cars (BEVs) and plug-in hybrids (PHEVs), communicate with the power grid to sell demand response services by either returning electricity to the grid or by throttling their charging rate.

Vehicle-to-grid can be used with gridable vehicles, that is, plug-in electric vehicles (BEVs and PHEVs), with grid capacity. Since at any given time 95 percent of cars are parked, the batteries in electric vehicles could be used to let electricity flow from the car to the electric distribution network and back. This represents a value to the utilities of up to $4,000 per year per car.

One notable V2G project in the United States is at the University of Delaware, where a V2G team headed by Dr. Willett Kempton has been conducting on-going research. An early operational implementation in Europe was conducted via the German government-funded MeRegioMobil project at the "KIT Smart Energy Home" of Karlsruhe Institute of Technology in cooperation with Opel as vehicle partner and utility EnBW providing grid expertise. Their goals are to educate the public about the environmental and economic benefits of V2G and enhance the product market. Other investigators are the Pacific Gas and Electric Company, Xcel Energy, the National Renewable Energy Laboratory, and, in the United Kingdom, the University of Warwick.
