Flexible generating portfolio as basis for high wind power plants penetration — Bosnia and Herzegovina case study

In the past 10 years, very intensive integration of wind power plants (WPP) into power systems worldwide is evident. This phenomenon can have significant impacts on the normal operation of certain power systems. Especially exposed are power systems that do not possess a flexible generation portfolio, where the biggest challenge for power systems with significant amounts of installed capacity in WPP are variations of their output power which need to be balanced. In this paper, possible variations of output power from WPP based on real, measured wind speed data are analyzed. Recommendations for power systems that want to remain/become self-sustaining i.e. independently satisfy consumer needs and enable smooth functioning, in spite of significant amounts of installed capacity in WPP are given. In this sense, some of the characteristics of power systems in the Southeast Europe (SEE) region are presented. Most of these power systems are characterized by dominant electricity generation from "slow-response" generation facilities, such as thermal power plants (TPP) based on coal and nuclear power plants (NPP). On the basis of gained results, a more detailed elaboration of possibilities of integrating WPP into the power system of Bosnia and Herzegovina (B&H) are done in this paper.
