Impact of cogeneration and small power producing facilities on the power system reliability indices

The author describes the models and computational techniques that simulate the operational behavior of cogeneration and small power-producing facilities and evaluates their impact on the reliability indices of power system load-points. These techniques evaluate the five basic reliability indices of the system load-points and quantify the impact of these facilities on the system reliability performance. The increased information that can be gained from these improved techniques is illustrated by the analysis of a typical system based on the Hellenic interconnected transmission system. The results demonstrate the increased information that can be gained about the reliability indices of the system load-points and the impact of these facilities on them. By varying the operational features of cogeneration facilities, a system planner can assess a number of additional system configurations which are not possible using existing techniques
