In this paper, an algorithm to construct an equivalent system with the ability to retain thermal line limits is presented. The application of Kron's reduction and power transfer distribution factor is used in the creation of the reduced system. The criteria for this method and its step-by-step procedure with the implementation to a small power system are described. Also, the result of its application to the IEEE 118 bus system is provided. 10aCERTS10apower systems10areliability and markets10aRM11-00110atransmission networks1 aJang, Wonhyeok1 aMohapatra, Saurav1 aOverbye, Thomas, J.1 aZhu, Hao uhttps://certs.lbl.gov/publications/line-limit-preserving-power-system
