As an attempt to fi ght global warming, many countries try to reduce CO2 emissions in the power sector by significantly increasing the proportion of renewable energies (RES-E). A highly intermeshed electricity transmission grid allows the achievement of this target cost-efficiently by enabling...

The present article analyses the effects caused by variable power. The analysis concerns a country-scale electricity system with a relatively high penetration of seasonally variable hydro power plants and wind farms in the total electricity generation in 2030. For this purpose, the Latvian...

A fast growth of installed wind power capacity has been experienced in several European countries. In Germany, notably high wind power capacities are planned in the North. If the existing transmission capacities between individual regions become insufficient, the electricity prices will differ...

Increasing renewable electricity generation and the electrification of industry, mobility, and heating through sector coupling pose significant challenges to grid operators in maintaining secure and reliable system operations. Demand-side sector coupling applications increase electricity demands...

A variety of recent policy measures have been advanced to promote interregional power transmission investment in the United States; among these are the designation of corridors on federal lands in western states and the identification of national interest electric transmission corridors across...

The expansion of offshore wind energy as well as the increase in electricity trade between the North Sea countries leads to a growing need for additional transmission capacity. Due to the predominantly remote locations of offshore wind farms, the majority of future connections will be...

A strong and intermeshed electricity grid allows the cost-efficient achievement of renewable energy targets by enabling the use of favorable sites and by facilitating the balancing of stochastic infeed from renewables and electricity demand. However, construction of new lines is currently...
