【Abstract】 A practical algorithm is presented.It can accomplish tracing the power system PV curves and searching for the maximum loading lim it point.On the process of iterations,its convergence can be accelerated and the numbers of the iteration can be decreased by use of the optim al multiplier in rectangular coordinates and the predictor- corrector technique.U sing the proposed method,the instability caused by the relatively light loaded condition can be avoided,the zigzagging phenom enon in solution can be reduced,and some specific properties will be im proved in ill- conditioned power system s.更多还原
