Abstract

This paper outlines a calculation method for ac load flow program for post contingency based on sensitivity factor for power system security calculated from dc power flow and implemented in MATLAB environment for post-contingency assessment. The contingency analysis plays a critical role in ensuring the safe, reliable, and efficient operation of power systems. It helps power system engineers identify potential problems and develop effective strategies for preventing or mitigating the impact of these problems on the power system. DC power flow provides a simpler approach to power flow by performing a number of approximations and simplifies the power flow process to a simple equation system. To this end, we have developed a MATLAB program appropriate for contingency studies considering line outage distribution factors (LODFs) and generation Shift distribution factors (GSDFs). The programs in MATLAB are built to perform two-way communication between a load flow and contingency analysis routine. To validate the proposed algorithm, comparison is made between the ac power flow from PowerWorld and approximated solution obtained by our algorithm. The accuracy of the proposed approach is demonstrated by applying it to a 6-bus test system. The calculation outcomes indicate an improved efficiency of the developed approach in respect to the execution time and the result quality
