Analysis of the Operational Impact of the Interconnected Wind Power Plant Selac on Enhancing the Quality of Supply and Operational Functionality of the Kosovo Power System

This paper deals with the problem of establishing the effects of the technical and functional integration of wind power plants (WPP) in the Kosovo Power System (KPS). The analysis pertains to establishing the impact and the effects of interconnecting the Selac Wind Power Plant on the voltage profile, on the fault, that is, short circuit levels, as well as on the fault-ride-through capability of the wind park generators on the electrically adjacent power system network. The case study analyzed the Selac WPP in the Mitrovica region of Kosovo. It has a total of twenty-seven wind turbines each with a power rating of 3.8 MW with the total installed power generating capacity of 102.6 MW representing approximately one-tenth of the overall power-generating capacity of KPS. The WPP has been appropriately modelled mathematically, and numerous wide-ranging simulations have been carried out pertaining to the related analysis under various load conditions of the KPS, both with and without the contribution of the Selac WPP. The DigSilent Power Factory software package was used to perform simulations and obtain the results. All simulations were performed using accurate factory-provided data for wind generators, cables, transformers, and lines.
