Until recently, it was considered one of the most effective directions in the development of the electric power industry to increase the share of renewable energy sources (RES) in the balance of power and electricity of power systems in the form of wind and solar power plants (wind turbines and solar power plants), the main advantages of which are considered to be the economy of fossil fuel (coal, gas, fuel oil) and reducing environmentally harmful emissions into the atmosphere. However, at the same time, the influence of renewable energy sources on the controllability of the modes of operation of electric power systems and on the reliability of the functioning of the RES remains completely unexplored. This brief analysis is devoted to the last question.
