The residual load and excess power generation of 30 European countries with a 100% penetration of variable renewable energy sources are explored in order to quantify the benefit of power transmission between countries. Estimates are based on extensive weather data, which allows for modelling of...

Flywheels can be used as storage elements in islanded power systems and, as a special case, in isolated wind plants, especially those running at almost constant speed and included as a component in diesel groups. Nowadays, systems with variable speed are under development, so the amount of...

The storage and balancing needs of a simplified European power system, which is based on wind and solar power generation only, are derived from an extensive weather-driven modeling of hourly power mismatches between generation and load. The storage energy capacity, the annual balancing energy...

We compare the cost of generating electricity with coal and wind in Chile. On average, we estimate that the levelized cost of coal, including externalities, is $84/MWh. It is efficient to abate air pollutants (SOx, NOx and PM2.5) but not CO2. With abatement the cost wrought by environmental...

This paper contributes to the literature on accounting for spatial characteristics in the analysis of stated choices. It is studied whether the present spatial allocation of turbines in a region affects choices on alternative programmes describing the future shape of wind power generation. Due...

A future energy system is likely to rely heavily on wind and solar PV. To quantify general features of such a weather dependent electricity supply in the contiguous US, wind and solar PV generation data are calculated, based on 32 years of weather data with temporal resolution of 1h and spatial...

In the past decade, wind power generation has taken center stage in renewable energy development. Currently, the mainstream power-train of a wind turbine system consists of mechanically geared doubly-fed induction generator with a partially rated converter. However, gearbox failures account for...
