Statistical Analysis of Power Generation of Wind Parks
AbstractRapid development of wind power plants and increasing of their generated variable power may cause perturbations of power system operating conditions and power unbalance. Wind power plants’ power does not depend on variation of power system load and may be forecasted with insufficient accuracy. That requires additional balancing capacities, energy storage equipment and controllable load. Comprehensive statistical analysis and estimation of operating power plants’ power may decrease the problems caused by wind power plants. The changes and their distributions and parameters of wind power plants’ generated power were analysed. Factors of power changes correlation and their values depending on power averaging windows are determined. Relationships of power correlations between separate wind parks and wind parks and consumers load are analysed and influence of wind direction and speed on wind parks’ generated power is evaluated.
