Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?
The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is …
… operation. Due to the increasing amount of intermittent energysources, such as wind and solar power, the energy system will require that theplants that run as base load today will be able to rapidly respond to changes in load.The present work investigates the operation of a coal …
… have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the increase in renewables …
Today’s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning …

Nätstudie av olika utföranden i normal- och reservdrift
Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This …
The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a …
… climate parameters (air temperature, globe temperature, relative humidity, wind angle and wind speed and solar radiation) were recorded in a weather-station. Inside the barn air temperature and relative humidity were recorded. The study also collected parameters reflecting the …
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which …
