Wind power, as a renewable source of energy, reduces the greenhouse gas emissions. For Finland, the technology also brings business opportunities, as the Finnish industry already has a position in the global, fast growing wind power market. The wind energy project within the Climtech Programme focused on the technology export potential of Finnish industry in wind power markets, and on the reduc...

Due to the diminishing reserves of fossil fuels and increased pollution from exploitation of these fuels, the world is focusing on the renewable energy sources. Wind is being considered as one of the prime next generation energy sources. Considerable amount of research is being carried out on the innovative designs for maximizing the performance of wind turbines. Furthermore, a lot of research ...

The September and October (2013) wind storms in Canterbury, New Zealand had highest worldwide reported windstorm damaged on centre pivot irrigation systems. Around 800 centre pivot has been damaged and it cost farmers millions dollars directly and indirectly. It was very difficult to find the engineering proofed recommendation for farmers to protect their irrigation systems during windstorms. T...

The distribution of neutron stars (NS's) is determined by stationary solution of the Fokker–Planck equation. In this work using the observed period changes for four systems: Vela X–1, GX 301–2, Her X–1 and Cen X–3 we determined D, the 'diffusion coefficient',– parameter from the Fokker–Planck equation. Using strong dependence of D on the velocity for Vela X–1 and GX 301–2, systems ac-creting fr...

Maintaining a wind turbine and ensuring secure is not easy because of long-term exposure to the environment and high installation locations. Wind turbines need fully functional conditionmonitoring and fault diagnosis systems that prevent accidents and reduce maintenance costs. This paper presents a simulator design for fault diagnosis of wind power systems and further proposes some fault diagno...

Remote offshore wind power plants are expected to be connected via HVDC systems to the main grids. The extension of single point-to-point HVDC systems into meshed HVDC grids is discussed actively. This leads the integration of DC technology into the collection grid of the wind farm to gain interest and relevance. Using DC technology in the collection grid demands the wind turbine systems to hav...

7 The increasing penetration of uncertain generation such as wind and solar in power systems imposes new challenges to the Unit Commitment (UC) problem, one of the most critical tasks in power systems operations. The two most common approaches to address these challenges — stochastic and robust optimization — have drawbacks that restrict their application to real-world systems. This paper demon...

In May of 2004, the IEA Wind Implementing Agreement (IA) established R&D Task 24, “Integration of Wind and Hydropower Systems.” Australia, Canada, Finland, Norway, Sweden, Switzerland, and the United States joined Task 24 with the goal of collaborating in the study of wind integration in a variety of electrical system configurations (load, generation, and transmission); hydro system configurati...

Recent research has demonstrated exciting potential for wind plant control systems to improve the cost of energy of wind plants. Wind plant controls seek to improve global wind plant performance over control systems in which each turbine optimizes only its individual performance by accounting for the way wind turbines interact through their wakes. While these technologies can be applied to exis...
