System and market integration of wind power in Denmark

Abstract

Denmark has more than 10 years of experience with a wind share of approximately 20 per cent. During these 10 years, electricity markets have been subject to developments with a key focus on integrating wind power as well as trading electricity with neighbouring countries. This article introduces a methodology to analyse and understand the current market integration of wind power and concludes that the majority of Danish wind power in the period 2004-2008 was used to meet the domestic demand. Based on a physical analysis, at least 63 per cent of Danish wind power was used domestically in 2008. To analyse the remaining 37 per cent, we must apply a market model to identify cause-effect relationships. The Danish case does not illustrate any upper limit for wind power integration, as also illustrated by Danish political targets to integrate 50 per cent by 2020. In recent years, Danish wind power has been financed solely by the electricity consumers, while maintaining production prices below the EU average. The net influence from wind power has been as low as 1-3 per cent of the consumer price.

Reviewing EnergyPLAN simulations and performance indicator applications in EnergyPLAN simulations

“…Hong et al [180] and Cerovac et al [198] use EnergyPLAN simulations to point towards the importance of flexible power plants to accommodate the fluctuating nature of RES; in these cases wind power in Croatia and China. This is in line with the logic of Lund et al's [213] analyses of excess power generation in Denmark.…”

Biogas upgrading and utilization: Current status and perspectives

“…The incentive for biogas upgrading relate to the larger scale transition of energy systems to renewable energy that is presently pursued by many countries. When releasing the energy supply from fossil fuels, the nature of the energy system changes towards a high share of fluctuating energy from wind and solar power and towards a high dependency on biomass resources (Danish Energy Agency, 2014a ;Lund et al, 2011). With respect to the role of biogas in the energy system, this creates economic and environmental incentives for biogas upgrading.…”

Future power market and sustainable energy solutions – The treatment of uncertainties in the daily operation of combined heat and power plants

“…As the market conditions in Denmark have proven their ability to integrate large shares of intermittent RES [1], these market conditions are perceived as representative for market systems with a high integration of intermittent RES. Likewise, Denmark has a relatively high amount of DH plants with flexible distributed CHP units.…”

“…The increased capacity of intermittent renewable energy sources (RES) increases the need for flexibility in the energy system [1,2]. Lund et al [3] found that district heating (DH) should have an increased interaction with the electricity system in future sustainable energy systems, as DH can help integrate flexible solutions and improve the energy efficiency of the system.…”
