摘要：A method for selecting a pilot bus with a sensitivity matrix is provided to improve a voltage stability of a power system by stably controlling a pilot bus voltage into a secondary voltage control method. A method for selecting a pilot bus with a sensitivity matrix comprises the following steps: a step for calculating a susceptance matrix about a bus of a power system(S100); a step for calculating a sensitivity matrix from a reverse matrix of the susceptance matrix(S110); a step for arranging the sensitivity matrix according to a size of a diagonal component of the sensitivity matrix(S120); a step for comparing a bus positioned in a smallest diagonal component among the diagonal component of the sensitivity matrix with a limited condition of the pilot bus(S130); and a step for selecting a bus corresponding to the smallest diagonal component among the diagonal component of the sensitivity matrix as a pilot bus(S150).
