Measure-correlate-predict (MCP) algorithms are used to predict the wind resource at target sites for wind power development. This paper describes some of the MCP approaches found in the literature and then compares the performance of four of them, using a common set of data from a variety of sites (complex terrain, coastal, offshore). The algorithms that are compared include a linear regression...

Abstract: In modern wind farms, maximum power point tracking (MPPT) is widely implemented. Using the MPPT method, each individual wind turbine is controlled by its pitch angle and tip speed ratio to generate the maximum active power. In a wind farm, the upstream wind turbine may cause power loss to its downstream wind turbines due to the wake effect. According to the wake model, downstream powe...

( The applicability of the inhalable convention for sampling aerosols relies on its being a valid model for typical sampling environments. The current convention is based on measurements carried out in external wind speeds between 1 and 4 m • s~'. However these measurements show a degree of wind speed dependence, and it is uncertain at present how valid the convention is for describing human as...

High costs, unreliable resources for long term use and extensive negative impact on our environment are such problems associated with traditional sources of energy and fossil fuels which make us move toward implementation of renewable sources of energy. Fossil fuel pollution and reserve depletion in oil producing countries caused by increasing demands, make wind energy an attractive source of e...

Proper knowledge of the wind characteristics of a site is of fundamental importance in estimating wind energy output from a selected wind turbine. The present paper focuses on assessing the suitability and accuracy of the fitted distribution function to the measured wind speed data for Baburband site in Sindh Pakistan. Comparison is made between the wind power densities obtained using the fitte...

Based on about 940,000 measurements of surface-water pCO2 obtained since the International Geophysical Year of 1956–59, the climatological, monthly distribution of pCO2 in the global surface waters representing mean non-El Ni * no conditions has been obtained with a spatial resolution of 41 51 for a reference year 1995. The monthly and annual net sea–air CO2 flux has been computed using the NCE...

This work demonstrates a techno-economical assessment of wind energy potential for four passes Tamil Nadu (Aralvaimozhi, Shencottah, Palghat, and Cumbum) with uncertainty factors. First, was carried out time-series data, the Weibull parameters, such as c (scale) k (shape), were determined using modern-era retrospective analysis research applications (MEERA) data set. Using these mean speed, mos...
