摘要
An acquisition method of the severest voltage stability margin based on coordinated continuation power flow is disclosed comprising: S1, calculating a partial derivative of initial voltage amplitude of a critical node with respect to the load level of each partition under the current load; S2, calculating the amount of the load growth of each partition according to the partial derivative and a preset load growth step length, and updating the active power output and current load based on a coordinated continuation power flow model; S3, judging whether a new voltage amplitude of the updated critical node is less than the initial voltage amplitude if the updated coordinated power flow converges; S4, judging whether the preset load growth step length is less than a convergence threshold if the new voltage amplitude is greater than or equal to the initial voltage amplitude, and acquiring the severest voltage stability margin if so.
