Wind Farms Generation Deviation in Electric Power System

Installed capacity of renewable energy sources as part of electric power systems, in particular wind farms, is growing rapidly. The Russian Federation has also adopted a set of legislative measures aimed for increasing the installed capacity of wind farms. In this regard, the paper devoted to assessing the impact of wind farms on active power control range of traditional power plants. The paper presents calculation results that make it possible to assess the fluctuations regularity of wind farms generation schedule over a long period of time. Numerical results were obtained using the Microsoft Excel software package.
