Wind changes influence on control of power systems with high percentage of wind power

This paper illustrates associated problems in terms of control and power balance of the power system with high percentage of wind power generation from the view of transmission system operator (TSO). Paper considers various types of wind farm designs and placement, and explains influence of these designs, in specific way, on managing power balance and control error. Available control reserve rapidity of active power generation is taken into account. Possibilities of managing balance in case of big wind generated deficit are given.
