  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Want to improve wind and solar power? Bring them together

    By combining intermittent renewable energy sources through hybrid projects, developers are taking advantage of the strengths of each. What’s keeping solar and wind power from fully taking over the electric grid? For starters, the sun only shines during the day. Wind blows intermittently, is ...

  • Does Wind Turbine Blade Length Really Matter?

    Simply put: Longer wind turbine blade length means greater power production. Blades capture the wind which forces the rotation of the rotor; longer blades means more area for the wind to push against, which means greater force and rotational power. However, how much difference does blade length make overall, in comparison to other factors? There is a standard formula that can be used to apply the ...

  • Is nuclear power our energy future — or a dinosaur in a death spiral?

    Identical data yield drastically different conclusions about the role nuclear will play in meeting climate goals. Nuclear power is dead. Long live nuclear power. Nuclear power is the only way forward. Nuclear power is a red herring. Nuclear power is too dangerous. Nuclear power is the safest power source around. Nuclear is nothing. Nuclear is everything. It is now generally agreed ...

  • ANFIS and ANN models for the estimation of wind and wave-induced current velocities at Joeutsu-Ogata coast

    In this study, the adaptive network-based fuzzy inference system (ANFIS) and artificial neural network (ANN) were employed to estimate the wind- and wave-induced coastal current velocities. The collected data at the Joeutsu-Ogata coast of the Japan Sea were used to develop the models. In the models, significant wave height, wave period, wind direction, water depth, incident wave angle, and ...

  • The comparison of magnetic values obtained from hall probes and measuring coils in synchronous generators

    Abstract This article gives a review of a part of measuring results obtained during factory tests and inspections of a wind mil power unit. Magnetic fields were measured by two different measuring methods and the results were compared consecutively. The article also gives the results of calculation of dynamic electromagnetic field by application of FEM to the model of a synchronous ...

  • How to measure the direction of current harmonics?

    If the generation side of the point-of-common-coupling (PCC) is essentially an islanded setup consisting of a few specific generators, then the amount of harmonics resulting from the generation "source" can be readily identified in a mathematical fashion from the relative impedance on the generation side of the PCC compared to the combined impedance on the load side of the PCC. (The source of ...

  • UK offshore load factors accelerate on tech breakthroughs: 10-year study

    UK offshore load factors accelerate on tech breakthroughs: 10-year study The Crown Estate’s Offshore Wind Operational report 2015 shows there has been a gradual increase in the load factor for the UK fleet since 2004 on the back of more productive wind turbines, wind farms being built at windier sites and improved plant availability. The Crown Estate manages UK sovereign ...

  • European Power Markets in Transition

    With European energy markets in transition, all market participants now face a number of potentially tricky challenges. A combination of EU initiatives, increasingly invasive regulations and a backdrop of falling and less volatile commodity prices, have precipitated an era of change and uncertainty in which there are fewer trading opportunities and profits are harder to come by. Analysis ...

  • Terminal characteristics of type 1 wind generating systems with magnetic saturation

    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 ...

  • Competition in Wind Power, Outcomes for the future

    Without a doubt, wind power is taking the lead as not only a renewable energy with a much lessened environmental impact, but it is also edging out the competition from fossil fuels with the distinct ability to lessen the impact on the wallet. Fossil fuel consumption, headed by traditional fuel sources such as oil and natural gas, are falling to the way side as having a significant difference in ...

  • Study on environmental impact model of grid-connected wind power generation

    As a clean and renewable energy source, wind power is independent from the traditional external energy change, which makes it one of the most promising ways of clean energy generation. It is well known that wind power has obvious energy saving efficiency. But for long-term consideration, wind power generation still has certain impacts on human life. Therefore, standing in the point of the ...

  • Wind power has increased by 175 MW in Spain in 2013, the lowest rate of growth in 16 years

    The wind sector installed 175 MW in Spain in 2013, up 0.77% on a year-by-year basis. This is the lowest growth rate in the sector since 1997, the year in which it was regulated for the first time in the Electrical Sector Law. On December 31st total accumulated power in the sector stood at 22,959 MW according to data compiled by the Spanish Wind Energy Association (AEE). This installed power is ...

  • 2013 to be Record Year for Offshore Wind
