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.

Download or read book Approaches to Stochastic Simulation of Waked Wind Fields in Wind Turbine Arrays written by Jae Sang Moon and published by . This book was released on 2016 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind turbines in a wind plant do not always experience free-stream flow fields. The flow fields inside a wind plant or wind farm, waked by upwind turbines, exhibit different dynamic characteristics. The International Electrotechnical Commission (IEC) standard 61400-1 for the design of wind turbines only considers a deterministic wake model for the design of a wind plant. This study is focused on the stochastic modeling of waked wind fields for assessing turbine loads using a regression-based approach. The waked wind velocity field is generated using Large-Eddy Simulation (LES). Stochastic characteristics of the generated waked wind velocity field, including the mean and turbulence components, are analyzed. Proper orthogonal decomposition (POD) and spectral methods are proposed to develop reduced-order engineering model-based wind velocity fields as alternatives to the LES-generated waked fields. The reduced-order model-based simulation employs either a subset of the POD eigenmodes or Fourier-based spectral simulation with parameters derived from LES in illustrations with a wake-generating turbine. With the spectral model, wake-related spectral parameters are estimated using Multivariate Multiple Linear Regression (MMLR). To validate the simulated wind fields based on the reduced-order models, wind turbine tower and blade loads are generated using aeroelastic simulation for a utility-scale wind turbine model and compared with those based on LES. This study also discusses the construction of a stochastic expanded-wake model for wind turbines experiencing fully and partially waked situations. The study's overall objective is to offer efficient stochastic approaches that are computationally tractable, when assessing the performance and loads of turbines operating in wakes. Validation studies are carried out by comparion with loads computed directly from LES wake fields.
Download or read book Stochastic Modelling of Electricity and Related Markets written by Fred Espen Benth and published by World Scientific. This book was released on 2008 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The markets for electricity, gas and temperature have distinctive features, which provide the focus for countless studies. For instance, electricity and gas prices may soar several magnitudes above their normal levels within a short time due to imbalances in supply and demand, yielding what is known as spikes in the spot prices. The markets are also largely influenced by seasons, since power demand for heating and cooling varies over the year. The incompleteness of the markets, due to nonstorability of electricity and temperature as well as limited storage capacity of gas, makes spot-forward hedging impossible. Moreover, futures contracts are typically settled over a time period rather than at a fixed date. All these aspects of the markets create new challenges when analyzing price dynamics of spot, futures and other derivatives.This book provides a concise and rigorous treatment on the stochastic modeling of energy markets. Ornstein?Uhlenbeck processes are described as the basic modeling tool for spot price dynamics, where innovations are driven by time-inhomogeneous jump processes. Temperature futures are studied based on a continuous higher-order autoregressive model for the temperature dynamics. The theory presented here pays special attention to the seasonality of volatility and the Samuelson effect. Empirical studies using data from electricity, temperature and gas markets are given to link theory to practice.
Download or read book Stochastic Physics and Climate Modelling written by Tim Palmer and published by Cambridge University Press. This book was released on 2018-03-01 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to promote the use of stochastic, or random, processes to understand, model and predict our climate system. One of the most important applications of this technique is in the representation of comprehensive climate models of processes which, although crucial, are too small or fast to be explicitly modeled. The book shows how stochastic methods can lead to improvements in climate simulation and prediction, compared with more conventional bulk-formula parameterization procedures. Beginning with expositions of the relevant mathematical theory, the book moves on to describe numerous practical applications. It covers the complete range of time scales of climate variability, from seasonal to decadal, centennial, and millennial. With contributions from leading experts in climate physics, this book is invaluable to anyone working on climate models, including graduate students and researchers in the atmospheric and oceanic sciences, numerical weather forecasting, climate prediction, climate modeling, and climate change.

Book excerpt: This book dedicates to publish exceptionally important and high-quality, agenda-setting research so as to tackle the key global and societal challenges of ensuring the provision of energy and protecting our environment for the future. The book appeals to chemical scientists, chemical and process engineers, energy researchers, bio-scientists, and environmental scientists from across academia, industry, and government. The scope is intentionally broad, and the book recognizes the complexity of issues and challenges relating to energy conversion and storage, alternative fuel technologies, and environmental science. The main topics of this book include but not limit to (1) alternative energy and the environment, (2) assessments of the condition of ecosystems and environmental quality, (3) behavior of and impacts of pollutants in atmosphere, soil, and water, (4) management of ecosystems, environment, and water resources, (5) modeling and regional environmental assessments (includes global change), (6) treatment/restoration of ecosystems, environment, and water resources, and (7) sustainable/renewable energy. All scales of studies and analysis, from impactful fundamental advances to interdisciplinary research across the (bio)chemical, (bio/geo) physical sciences, and chemical engineering disciplines are welcomed. So, this book is linked to the energy-environment nexus and is of significant general interest to our community-spanning readership.
