Optimal grid integration of wind power plants in Croatian 110 kV network

Wind power projects in Croatia are demanded on a larger scale in the recent few years. However, Croatian Transmission System Operator (TSO) has many problems with the quantity of capacity asked for grid connection resulting in many places with large scale line congestion. Transmission network is not ready for such big penetration of real power with stochastic nature produced by a large number of wind power units which was proven with many load flow analysis carried by system operator. In this paper one example of two different developers asking for grid connection on the same 110 kV line is presented. Also, current and future states of network are analyzed. Main problems are detected and measures for grid integration of both wind power plants are suggested.
