Distribution systems restoration using the Interior Point Method and sensibility analysis

This Panel Discussion proposes the development of methodologies to solve the Distribution System restoration problem, according to multiple objectives, such as to restore as much consumers as possible with minimal switching operations. This methodology uses graph theory to identify out-of-service areas and loops in the system. After that, the system switches are opened and closed based on a sensibility index, obtained from an Optimum Power Flow (OPF) algorithm using the Interior Point Method (IPM). This methodology solves the problem step-by-step, providing a feasible switching operation sequence. The results are compared with some systems presented in the literature.
