Calculating the sequence of stationary modes in power distribution networks of Russia for wide-scale integration of renewable energy based installations

The global trend of the past decades on the development of the decentralized power generation concept is associated with the growing number of power plants integrated into power distribution networks including those employing renewable energy sources. In recent years, high-capacity wind power and so...
