The necessity of research into WPP’s rotating parts inertia moment’s influence upon the automatic frequency and power controlling (AFPC) in the united power system (UPS) was proven. At that the inertia moment rates as a way to simplify the mode of the automatic frequency and power controlling.The mathematical model of electricity generation on WPP, belonging to the UPS, was elaborated on the basis of the frequency and power controlling universal model by adding the corresponding system of differential-algebraic equations to the source equations set.The numerical modeling of the automatic frequency controlling processes in the Ukrainian UPS was carried out using generators-controllers and consumer-controllers as controllers. The total capacity of wind power in the power system was established as equal to 3GW.In the investigated range of WPP’s time constants an acceptable frequency controlling process was proved to be unrealizable even with all HPP capacities (3 GW) involved. However, the use of controller-consumers with total capacity of 3 GW allows frequency controlling in accordance with the requirements of ENTSO-E European energy network regardless of WPP inertia moment.
