Krylov subspace methods for available transfer capability margins calculations


Hojabri, Mojgan and Hizam, Hashim and Mariun, Norman and Abdullah, Senan Mahmood (2009) Krylov subspace methods for available transfer capability margins calculations. In: 2009 IEEE Student Conference on Research and Development (SCOReD 2009), 16-18 Nov. 2009, UPM, Serdang, Selangor. (pp. 320-323).


Nowadays considering more accuracy and speed to compute Available Transfer Capabilities (ATC) are important for electricity markets. Most studies involved load flow based and contingencies that often can be performed in reasonable time with the use of linear methods. Since the limitations of linear ATC calculations is the error produced by neglecting the nonlinear nature of real power flows. This paper presents Krylov Subspace methods that can reduce this error. By applying these methods for calculating ATC, the speed and the accuracy of them are calculated and compared to find the best one. All computations are tested on IEEE-30 bus system in MATLAB 7.1.
