Robust Dynamic Reconfiguration of Three-phase Unbalanced Active Distribution Network
摘要
Abstract
The optimization effect and application value of network reconfiguration scheme can be improved considering the three-phase unbalanced operation of distribution network and the uncertainty of injection power. Firstly, the uncertainty of distributed generators and load injection power is modeled by the affine number, and the reconfiguration period is divided. The two-stage robust dynamic reconfiguration model of distribution network with uncertainty budget is established based on the three-phase Distflow power flow equation, which takes optimal active power of network loss as objective function. In order to efficiently solve the model, an optimal equidistant piecewise linear approximation algorithm is adopted for the precision-controlled linear relaxation of the model, and the column-and-constraint generation method is used to solve it iteratively. A standardized distribution test system is used to verify the feasibility and effectiveness of the proposed model, which shows that the conservatism and robustness of the reconfiguration scheme can be further adjusted by controlling the uncertainty budget.关键词
