Experience curves for wind power
The objective of this study was to improve the understanding of the use of different experience curves in energy analysis. The study was based on the application of experience curves to wind power systems, but the approach is generic and can be used in other energy technologies. In the study, experience curves for wind power were developed, and it has been demonstrated that different types of ...

Socio-technical analysis of the introduction of wind power in the Netherlands and Denmark
Why was Denmark more successful in the introduction of wind power than the Netherlands? In this paper, we analyse both development processes. Our analytical framework consists of a combination of the socio-technical systems approach, which points at the importance of the openings that must be present at both the niche level: the regime level and the landscape level, for an innovation to be ...

A novel dual stator-winding induction generator system applied in wind power generation
This paper presents a novel usage of 6/3-phase dual stator-winding induction generator (DWIG) with a static excitation power controller (SEC) as a wind power generator. This generator is composed of a standard squirrel-cage rotor and two sets of winding housed in the stator slots. One is referred to as the 6-phase power winding, and the other is defined as the 3-phase control winding. On the ...

On limits for wind power generation
The amount of wind power in the world increases fast. The background for this development is improved technology, decreased costs for the units and an increased concern of the environmental problems of competing technologies such as fossil fuels. For the future, it is now interesting to evaluate where the limits are for wind power generation, and which points are crucial. Since there is no power ...

Analysing the wind turbine innovation systems in The Netherlands and Denmark using the cyclic innovation model
This paper analyses the development of wind power in The Netherlands and Denmark in the period 1973-2000 with the cyclic innovation model (CIM). CIM regards innovation as a cyclic process in which different actors constantly develop and exchange knowledge through four different types of cycles: hard science cycle, soft science cycle, integrated engineering cycle, and differentiated valorisation ...

Trading wind in a hydro-dominated power pool system
In 1996, the Danish government launched an ambitious energy plan, Energy 21, describing a way to develop the energy sector in a more sustainable direction. Wind power plays an important role in the plan, and as a consequence there will be a very high penetration of wind energy in the electricity sector. This will put in focus issues of fitting a variable energy source into a stable supply system. ...

Development of PSO-based robust controller for maximising wind penetration
In this paper, a new robust controller has been proposed for attaining the maximum safe instantaneous wind penetration. Particle swarm optimisation (PSO)-based algorithm has been developed to obtain the maximum safe instantaneous penetration by the optimisation of grid parameters. The developed algorithm has been tested on modified IEEE 14-bus system. The effectiveness of the proposed methodology ...

Wind power prefeasibility study for agricultural applications in Kerman, Iran: a case study
In the present paper, wind characteristics have been analysed for three agricultural sectors in Kerman (30°15'N,56°58'E), Iran. Wind data collected from three synoptic stations for the period of July 2006 to June 2011 at the height of 40 m has been used to study the monthly and annual wind energy potential. Two statistical methods (Meteorological and Weibull) have been applied to ...

On methodology for modelling wind power impact on power systems
There is a continuous discussion going on concerning the integration cost of wind power. The integration cost can, for example, be defined as the extra costs in the rest of the system when wind power is introduced, compared with the situation without wind power. The result of the studies depends on both parameters and the method used. The aim of this paper is to structure the methods in order to ...

International energy technology collaboration: wind power integration into electricity systems
A rapid growth of wind power since the 1990s has led to notable market shares in some electricity markets. This growth is concentrated in a few countries with effective Research, Development and Demonstration (RD&D) programmes and with policies that support its diffusion into the market place. The speed and depth of its penetration in these electricity markets have amplified the need to address ...
