If loads in electric power systems approach the critical loading condition, the determinant of Jacobian matrix comes near zero, and V-Q sensitivities increase rapidly, or the convergence characteristics of load flow calculation becomes poor. When we try to increase the load level above this loading conditions, system voltages become unstable. In this paper the algorithm of computing the critical loading condition for voltage stability nearest to a given loading condition is proposed. The proposed method of detecting this condition is to increase the load in the direction determined by the gradient of determinant of Jacobian matrix, and to stop when V-Q sensitivity is very large compared to that in the given operating condition or when load flow calculation is not converged. Then we suggested this last loading condition as an extreme loading condition. In this calculation process the efficient algorithm for computing the gradient of determinant of Jacobian matrix was suggested. It is shown that results calculated by applying this proposed algorithm to large test power systems can be suggested as extreme loading condition.
