Wind power, distrubted generation and transmission: integration of 50+ percent wind power?

Abstract

Denmark has the World?s highest penetration of wind power in electricity generation with a share of 15.0% of total domestic demand in 2002 (DEA, 2004). This is unevenly distributed in the two electricity systems of Denmark giving a share as high as 20.7% in Western Denmark in 2003 up from 18.3% in 2002 (Eltra, 2004). At the same time, Denmark has other forms of distributed generation e.g. extensive CHP plants for district heating or for covering industrial heat demands. This results in a relatively high fuel efficiency as well as a technically complex energy system. This article deliberates the possibilities for integration of even more wind power using new power balancing strategies that exploit the possibilities given by the existence of CHP plants as well as the impact of heat pumps for district heating. The analyses demonstrate that it is possible to accommodate 50% or more wind power without relying on import or export for power balancing. The impacts on the transmission system are furthermore analysed demonstrating that new strategies for balancing power generation and power demand (power balancing strategies) also influence grid losses and the requirements of the transmission grid. If new power balancing strategies are not applied, costly grid expansions will follow expansions in installed wind power capacity.
