Region based reconfiguration of distribution network: A post-contingency security solution

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 meth...
