Research of the Number and Installed Capacity of Solar and Wind Power Plants in Interregional and Regional Power Systems in the Russian UPS

Abstract

There is significant volumes of construction and commissioning of solar and wind power plants since 2014 in the United power system of Russia, therefore new engineering tasks are being set for Russian power engineers. Operating modesof solar and wind power plants directly depend on external uncontrollable factors - solar and wind activity. An additional feature of the planning of the wind and solar power plants operation modes is their instantaneous termination of power output in the event of the disappearance of the wind or the sun, respectively. Therefore, the termination of the power output is a “failure”, which creates an imbalance of active power in the system. To cover it, it is necessary to place active power reserves at the thermal or hydro power plants in advance, and the value of this reserve should be equal to the capacity of the largest wind and/or solar power plant. Systematic and consolidated information on the composition, quantity and installed capacity of wind and solar power plants in the United power system of Russia is not published in the public domain. Therefore, the purpose of this study is to establish the quantity and installed capacity of wind and solar power plants, as well as to identify the most powerful wind and solar power plants in Russia.
