Available in PDF, EPUB and Kindle. Book excerpt: The economic feasibility of installing a wind energy conversion system at a given site depends on an accurate assessment of the wind characteristics at that site. To accomplish this, data records must be analyzed effectively. This report utilizes statistical methods and probability models to determine optimal evaluation procedures for survey data. Several years of hourly records from five typical Midwest sites, one high tower Midwest site, and one Rocky Mountain site provide a data base to develop the models and procedures. The minimum duration of survey is analyzed as a function of desired confidence level and acceptable tolerance range. Alternate survey procedures are discussed in terms of total survey duration and number of recorded values. Single year velocity records appear acceptable for velocity statistics, but are marginal for wind power estimates unless additional information is available. Persistence of the wind is measured in terms of velocity run duration, and a simple but apparently general model is developed for the probability of run duration. This model, which is calibrated to the average velocity, is based on the co linearity of probability versus run duration after each has been logarithmically transformed. Autocorrelation and cross correlation functions of both wind velocity and wind power are analyzed. The observed histograms for velocities exhibit a reasonable fit to both the Chi -2 and Weibull distributions, and the wind power appears to agree with distributions derived from these.

Available in PDF, EPUB and Kindle. Book excerpt: In order to investigate operating characteristics of a wind energy conversion system it is often desirable to have a sequential record of wind speeds. Sometimes a long enough actual data record is not available at the time an analysis is needed. This may be the case if, e.g., data are recorded three times a day at a candidate wind turbine site, and then the hourly performance of generated power is desired. In such cases it is often possible to use statistical characteristics of the wind speed data to calibrate a stochastic model and then generate a simulated wind speed time series. Any length of record may be simulated by this method, and desired system characteristics may be studied. A simple wind speed simulation model, WEISIM, is developed based on the Weibull probability distribution for wind speeds with a correction based on the lag-one autocorrelation value. The model can simulate at rates from one a second to one an hour, and wind speeds can represent short-term averages (e.g., 1-sec averages) or longer-term averages (e.g., 1-min or 1 hr averages). The validity of the model is verified with PNL data for both histogram characteristics and persistance characteristics.

Available in PDF, EPUB and Kindle. Book excerpt: Growing energy demand and environmental consciousness have re-evoked human interest in wind energy. As a result, wind is the fastest growing energy source in the world today. Policy frame works and action plans have already been for- lated at various corners for meeting at least 20 per cent of the global energy - mand with new-renewables by 2010, among which wind is going to be the major player. In view of the rapid growth of wind industry, Universities, all around the world, have given due emphasis to wind energy technology in their undergraduate and graduate curriculum. These academic programmes attract students from diver- fied backgrounds, ranging from social science to engineering and technology. Fundamentals of wind energy conversion, which is discussed in the preliminary chapters of this book, have these students as the target group. Advanced resource analysis tools derived and applied are beneficial to academics and researchers working in this area. The Wind Energy Resource Analysis (WERA) software, provided with the book, is an effective tool for wind energy practitioners for - sessing the energy potential and simulating turbine performance at prospective sites.

Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, the need to exploit renewable energy resources has been provided an impetus, by many governing bodies through favorable policy making and investment in this sector. This thesis focuses on implementing an efficient control scheme for the existing wind power systems. Particularly, this research is interested in implementing the theory of Singular Perturbation & Time Scales to achieve model order reduction and separation of slow and fast dynamics inherent to the Wind Energy Conversion System. Moreover, this decoupling of dynamics will assist in separation of time scales, simpler low order slow and fast controllers designs thereby enhancing the reliability of controllers and significant reduction in real-time computations. The model order reduction, using this methodology does not impair the system dynamics in any way. The analysis and synthesis is carried out for initial value problems, deterministic and stochastic optimal control problems via time scale separation. The implementation of the various control algorithms is validated through extensive simulations. The results of the simulations and research provide valuable insights into the successful development of optimal controllers that are computationally more efficient.
