A., De Souza, A. C. Z., & Quintana, V. H. (1996). Comparison of performance indices for detection of proximity to voltage collapse. IEEE Transactions on Power Systems, 11(3), 1441–1450. https://doi.org/10.1109/59.535685The paper proposes a new test function to be used in an existent performance index for detection of proximity to a static voltage collapse point. This test function is based on a reduction of the load flow Jacobian with respect to the critical bus of a system. The test function is compared with known singular values and eigenvalues indices, and with other previously proposed test functions. A thorough analysis of the similarities, advantages, and disadvantages of all these indices and test functions is presented. The techniques are tested and compared on the IEEE 300 bus test system, showing the effect of system characteristics and limits in these indices and functions.enJacobian matricesEigenvalues and eigenfunctionsvoltagebifurcationsystem testingpower system planningpower system modelingequationsload flow analysisArticle10.1109/59.535685
