Control power (regulating power, balancing power) is used to quickly restore the supply-demand balance in power systems. Variable renewable energy sources (VRE) such as wind and solar power are often thought to increase the reserve requirement significantly. This paper provides a comprehensive...

Wind power generation of electricity has gained popular support because of its low environmental impact and because of its low costs relative to other renewable energy sources. However, concerns have been raised in the power sector that wind power generation will come with the price of increased...

This paper studies the interaction between hydro and wind power in hydro-thermal-wind power system. Socially efficient and monopoly hydropower allocation solutions are presented. Market power utilization potential for hydropower is reduced during low demand periods when residual demand crosses...

The North and Baltic Sea Grid is one of the largest pan-European infrastructure projects raising high hopes regarding the potential of harnessing large amounts of renewable electricity, but also concerns about the implementation in largely nationally dominated regulatory regimes. The paper...

With greater penetration of renewable generation, the uncertainty faced in electricity markets has increased substantially. Conventionally, generators are assigned a pre-dispatch quantity in advance of real time, based on estimates of uncertain quantities. Expensive real time adjustments then...

Subsidies to renewable energy are costly and contentious. We estimate the reduction in prices that follows from the subsidized entry of wind power in the Nordic electricity market. A relatively small-scale entry of renewables leads to a large-scale transfer of surplus from the incumbent...
