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...

This paper discusses the potential for electricity generation on Hong Kong islands through an analysis of the local weather data and typical wind turbine characteristics. An optimum wind speed, uop, is proposed to choose an optimal type of wind turbine for different weather conditions. A...

This paper presents a dynamic model for variable speed wind energy conversion systems, equipped with a variable pitch wind turbine, a synchronous electrical generator, and a full power converter, specially developed for its use in power system stability studies involving large networks, with a...

This paper deals with the non-linear control of wind farms equipped with doubly fed induction generators (DFIGs). Both active and reactive wind farm powers are employed in two non-linear control laws in order to increase the damping of the oscillation modes of a power system. The proposed...

Wind power generation and its impacts on electricity prices has strongly increased in the EU. Therefore, appropriate mark-to-market evaluation of new investments in wind power and energy storage plants should consider the fluctuant generation of wind power and uncertain electricity prices, which...

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...

For conventional HAWT (horizontal axis wind turbines), the rotor speed is maintained constant while the blade tip speed changes continuously. This reduces considerably the power performance of the wind turbine particularly at high wind speeds where the tip speed ratio is small. With growth of...
