Techno-economic Analysis of Methods to reduce Damage due to Voltage Dips

A voltage dip is a Power-Quality phenomenon, often caused by short circuits in the electricity grid, in which the supplying voltage decreases during a short period of time (typically <2s). Some process components, such as variable speed drives and computers, are extremely sensitive to such dips, which may result in a complete process outage.

Ocean grids around Europe

Several European countries have a policy to encourage the development of renewable en-ergy sources. This is identified in e.g. the European green paper Energy strategy for a sus-tainable, competitive and secure energy supply (March 2006). In the transition towards a European sustainable energy system for the future and to reduce the dependency of im-ported primary energy sources such as oil and gas, the development of offshore wind power is an essential element.
