Abstract
The basic causes of technological failures in the US, EU, and Russian power grids are analyzed. It is shown that wind loads are of key importance for grid failures across all the climatic impacts. Observations of Russian meteorological stations are used for calculating the probabilistic characteristics of wind speed across different Russian regions. Regional power-grid-operator data on technological failures are used for proposing the probabilistic model of the failure-free operation of power grids as a wind-speed function. The climate projections make it possible to show that likely changes in the wind conditions across Russia in the next several decades are capable of affecting the power-supply reliability in several regions of the country. In particular, the increase in the frequency of power-grid failures could be up to 25% in the northwestern part of European Russia and up to 50% in the Russian Far East.
