To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

This paper proposes a simple method of incorporating magnetic saturation in determining terminal characteristics of a type 1 wind generating system employing a squirrel–cage induction generator. In determining the terminal characteristics, the generator is represented by its traditional per–phase equivalent circuit as well as two–axis model. In both cases, the magnetic saturation is carefully ...

This paper presents the development and qualitative validation of a doubly-fed induction generator (DFIG) wind turbine model that is represented in terms of behaviour equations of each of the subsystems, mainly the turbine rotor, the drive train, the induction generator, the power converters and associated control systems and a protection system. Simulation results obtained from the models are ...

This paper studies the 'catching–up' process of China's emerging wind turbine manufacturing ecosystem, and analyses the dynamics of the shifting collaborative innovation network for the period 1980–2011. We have focused on the leading wind turbine manufacturers [i.e., manufacturers of entire wind turbine system integrators (EWSIs)], as well as manufacturers of the turbines' sub–ecosystems (i.e., ...

Increasing global emissions of carbon dioxide (CO2), a heat-trapping gas, are pushing the world into dangerous territory, closing the window of time to avert the worst consequences of higher temperatures, such as melting ice and rising seas. Since the dawn of the Industrial Revolution, carbon emissions from burning fossil fuels have grown exponentially. Despite wide agreement by governments on ...

This paper investigates the operation and control of multiple Distributed Generation (DG) systems interconnected to the utility in the form of microgrid. The developed model of the microgrid consists of microturbine generation system, converter-based DG system with stiff DC source, synchronous-generator-based DG system and wind power system with induction generator. The Simulation model of the ...

The volatile fuel prices for electricity generation, elevated concerns about global warming and energy security has prompted countries to look for alternative energy sources. One of the alternative energy sources is ocean energy. Currently, there is few ocean energy technologies that are commercially available to harness electrical energy from ocean despite the fact that ocean covers more than ...

Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...

A wind energy conversion system (WECS) differs from a conventional power system. The power output of a conventional power plant can be controlled whereas; the power output of a WECS depends on the wind. This nature of WECS makes it difficult for analysis, design and management. Various approaches have been developed to study the behaviour of WECS. In this paper, the steady-state characteristics ...

Ontario's Green Energy and Green Economy Act, 2009 (the 'Act') received Royal Assent on May 14, 2009. The Act's aim is to foster the growth of renewable energy projects, promote a green economy and energy conservation and to encourage the efficient use of energy. Its scope equals its intended impact on Ontario's energy sector: both are substantial. To realize its objects, the Act creates the ...

Depending on your position, the federal stimulus money is either a jobs builder or a national budget buster. The Energy Information Administration offers another take. In a recent analysis, the EIA finds that stimulus money should reduce what consumers and businesses pay to heat, cool and light buildings. The federal agency this month updated its annual energy outlook to compare how energy ...

Isolated wind farms employ simple squirrel cage induction generators driven by variable speed wind turbines. Lacking control capability, such generation can contribute very little to network support. Wind turbines mostly do not take part in voltage and frequency control and if a disturbance occurs, the turbines may be disconnected and reconnected when normal operation has been resumed. From ...

Connecting variable speed wind turbine connected to the grid requires a proper control of the inverter to improve the power quality for the system. The vector control of an inverter connected to the grid is presented. The proposed control technique implies a hysteresis current controller in the inner loop. The complete control system has been developed, analysed, and validated by simulation ...

Due to wind speed variations, the output power of wind turbines fluctuates. These power fluctuations make the wind power undispatchable. Furthermore, they can cause frequency deviations and power outage particularly when wind power penetration is significant. This paper presents a novel control method to mitigate the power fluctuations using the rotor inertia as an energy storage component. ...
