[0145] Such as Figure 6 As shown, the present invention proposes an active distribution network optimal operation method based on the improved information gap decision theory. The present invention first establishes an active distribution network optimal operation mathematical model based on the improved information gap decision theory. The objective is to maximize the uncertainty of the active distribution network, and at the same time satisfy the safe operation constraints of the active distribution network. The established model is a nonlinear model.
[0146] Secondly, through the introduction of variables, the established model is transformed into a standard second-order cone model for solution.
[0147] The "ε-relaxation" method proposed by Ben-Tal and Nemirovski is used to approximate the polyhedral description of the convex second-order cone, but it is difficult to solve MI-SOCP. Therefore, the present invention uses mathematical methods to convert MI-SOCP into MILP. ...
