Balance costs for windpower
(Master thesis, 2009)Wind power scheduling is subject to high forecast uncertainty compared to the dominant Norwegian energy source, hydro power. The regulating market, also known as the balance market, is a market solution for optimal operation ... -
Balancing Costs for Wind Power
(Master thesis, 2007)Nordel is the organisation for the Nordel synchronous system, held by the Nordic Transmission System Operators. In their work to harmonise the Nordic electricity markets they have agreed upon harmonising the Nordic balance ... -
Balancing of Offshore Wind Power in Mid-Norway: Implementation of a load frequency control scheme for handling secondary control challenges caused by wind power
(Master thesis, 2009)In order to comply with governmentally announced greenhouse gas emission reductions goals and to consolidate an independent and stable electric power and energy supply, Norway must increase its installed renewable energy ... -
Beredskap i regionalnett: En risikobasert tilnærming til lagerhold
(Master thesis, 2008)Det er i denne rapporten utviklet en metodikk for å kartlegge beredskapsbehov for reservekomponenter og utstyr spesielt tilpasset regionale kraftnett. Metoden er anvendt i praksis ved en analyse utført på regionalnettet ... -
Bidding Wind Power on the Day-Ahead Market by Minimizing the Imbalance Costs.
(Master thesis, 2007)For wind power to participate in the short-term power market, forecasts up to 36 hours ahead of the hour of operation are required. These forecasts are never perfect, and the resulting wind power mismatch implies imbalance ... -
