<p>The present invention relates to a method for optimizing the optimal power flow of distributed generations, comprising the following steps: A, initializing variables in a distribution network; B, performing a power flow calculation on the distribution network; C, judging whether there is a circuit overload, and whether active and reactive power outputs of generators and the distributed generations cross the boundary; D, jumping to a step E if constraint equations are all met, otherwise, jumping to a step F; E, judging whether the value of an objective function is the smallest, if so, jumping to a step J, otherwise, jumping to a step F; F, correcting a loss correlation coefficient; G, calculating a Jacobean matrix and a Hessian matrix; H, creating a sub-problem of sequential quadratic programming, and solving search direction and step size; I, correcting the power output at a slack bus and the power output of each distributed generation, and jumping to the step B; and J, outputting an optimal power flow result. The method of the present invention provides a basis of calculation on access capacity for determining the access of the distributed generations to a distribution network, is simple in calculation and low in complexity, and can rapidly calculate the power outputs of the distributed generations.</p> |
