THE INFLUENCE OF WIND SPEED PROBABILITY DISTRIBUTION PARAMETERS ON THE ENERGY EFFICIENCY OF COASTAL AND OFFSHORE WIND FARMS IN ENCLOSED SEAS: A CASE STUDY OF THE AZOV-BLACK SEA REGION OF UKRAINE

The problems of determining the main parameters of probability distributions of wind speed, assessing their impact on the energy efficiency of wind power plants and the characteristics of power generation variability are considered. Energy efficiency is characterized by the power factor. Its calculation is performed using the Weibull distribution. The primary parameters are the average wind speed and the scale and shape parameters of the distribution. Possible limits of the ranges of parameter changes in the Azov-Black Sea region are determined. An analysis of current databases and available results of instrumental measurements of wind speed in the studied region is carried out to obtain quantitative estimates of the parameters. The need for additional short-term measurements of wind speed at the construction sites of wind power plants is justified to adjust information from multi-year databases. Mathematical models are developed, and a numerical experiment is conducted to determine the achievable annual value of capacity factor and characteristics of power generation variability by coastal and offshore plants during the year in the region.
