Grid integration of wind power plants in congested line

Wind power projects in Croatia are in commencement but are also being 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, especially in 110 kV network. In many places grid is not ready for such big penetration of intermittent power 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.
