| Sumario: | The N-1 security principle is a key principle for distribution operation. However, it is not taken into account in modern distribution network reconfiguration models, which cannot satisfy security demands. And in order to solve this fundamental problem, this paper proposes a new reconfiguration method for distribution network considering N-1 security constraints. Firstly, distribution system security region are introduced to analyze real-time security as well as sub-concepts of security boundary and security distance are analyzed. Secondly, distribution feeder reconfiguration model is introduced to minimize the net loss considering N-1 security operation constraints. Thirdly, the model is solved by the improved genetic algorithm. Finally, the model of this paper is compared to the existing model and the results show that the reconfiguration strategy can satisfy the N-1 security principle and is better than modern models considering security of power systems, which prove that the proposed model and solving method are correct and effective. |
