Syfte

The course is aiming at giving the student basic knowledge in wind power and its use in society. It also aims at identifying and explaining wind power technology, -systems and integration to the power system in an engineering context. The course has great relevance to the sustainable development of the energy system where wind power now is the most expansive renewable energy source with a global yearly rate of expansion of 20%. The need for electrical energy is constantly growing at the same time as the requirements for environmentally friendly electricity production are increasing. The expansion of environmentally friendly alternatives is gradually increasing as a result of global and national goals for renewables. In Sweden, the electricity certificate system exists as a driving force for the expansion of renewables. Wind power is expected to gradually take an increasing share as the existing nuclear power decreases and probably is phased out before 2040. With larger share of renewable electricity, the electric power system will need more flexibility as a result of reduced regulatory margins. In order to maintain the high operational reliability of the electricity supply, the requirements for wind power systems will also increase. Especially for newly established and coming large-scale wind power plants both onshore and offshore. In the course, the situation and possibilities for wind power to contribute to energy support in Sweden and globally are penetrated. We study among other things the wind as a resource of energy, the production and construction of the plants, and environmental issues.
