This paper investigates the theoretical foundations and practical applications of the modal analysis technique applied to voltage stability assessment. Improvements are made to the existing technique. The results show that two reduced Jacobian matrices, one related to reactive power and the other related to active power, are needed for extracting complete modal information. There is no need to use a full Jacobian matrix for modal analysis. As a preliminary result, a technically sound generator participation factor index is proposed based on the findings.319461950Kundur, P., (1994) Power System Stability and Control, p. 1176. , New York: McGraw-HillTaylor, C., (1994) Power System Voltage Stability, p. 273. , New York: McGraw-HillVoltage stability of power systems concepts, analytical tools, and industry experience (1990), IEEE Special Publication, 90TH0358-2-PWRPal, M.K., Voltage stability conditions considering load characteristics (1992) IEEE Transactions on Power Systems, 7 (1), pp. 243-249Gao, B., Morison, G.K., Kundur, P., Voltage stability evaluation using modal analysis (1992) IEEE Trans. on Power Systems, 7 (4), pp. 1529-1542Mansour, Y., Xu, W., Alvarado, F., Rinzin, C., SVC placement and transmission line reinforcement using critical modes (1994) IEEE Trans. on Power Systems, 9 (2), pp. 757-763Morison, G.K., Gao, B., Kundur, P., Voltage stability analysis using static and dynamic approaches (1993) IEEE Trans. on Power Systems, 8 (3), pp. 1159-1171Aik, D.L.H., Andersson, G., Use of participation factors in modal voltage stability analysis of multi-infeed HVDC systems (1998) IEEE Trans. on Power Delivery, 13 (1), pp. 203-210Suggested techniques for voltage stability analysis (1993), IEEE Working Group on Voltage Stability, IEEE Power Eng.
