Probabilistic Reliability Planning at Idaho Power: 75-Year Buildout Transmission Strategies

摘要

This paper presents a probabilistic reliability planning (PRP) approach for selecting Treasure Valley (TV) 75-year buildout transmission strategies at Idaho Power Company (IPC). Paper illustrates IPC's experience in applying a probabilistic reliability-based approach to develop long-term transmission system planning strategies. The PRP approach is based on analytical enumeration technique. A Computer Program Transmission Reliability Evaluation of Large Scale Systems (TRELSS) developed by Electric Power Research Institute (EPRI) has been used for evaluating composite system reliability. Three concurrent long-term 75-year transmission planning strategies named ISLD, LOOP and HYBR have been evaluated and compared. The results obtained showed merits and demerits of analyzed TV buildout strategies.
