A NOVEL NETWORK REDUCTION TECHNIQUE FOR POWER SYSTEMPLANNING STUDIES WITH CONGESTION PROFILE

M.Thenmozhi, R.Sathishkumar

The need for studying large scale power systems is increasing due to long distance power transfers and planning of highly interconnected areas. Large systems are difficult to handle if not reduced. This paper focuses on reduction technique yields with a given grouping of buses based on power transfer distribution factors (PTDFs) in order to achieve better calculation performance, easier handling of large amount of data and better observation of the results. This method will be applied for OPF studies, and the OPF results are compared with those from the original networks in terms of the locational marginal prices (LMP), and generation profiles. Modified IEEE 118-bus system and the simulation results are compared has been used to demonstrate the effectiveness of the proposed method.
