Coordinated Distribution Lines Maintenance with Network Reconfiguration Considering Voltage Deviation

The maintenance scheduling of distribution components is important to maintain distribution reliability. With the development of smart grids, the distribution reconfiguration gains more and more concerns. The maintenance scheduling of distribution components should be coordinated with distribution reconfiguration. Such co-optimization model of maintenance scheduling and distribution reconfiguration remains to be studied. This paper established the coordinated optimization model and algorithm of maintenance scheduling and network reconfiguration in distribution systems. The coupling constraints between maintenance scheduling and distribution reconfiguration are proposed. The voltage deviation is considered in the co-optimization model. Case studies show the effectiveness and improvement of the presented model and solution methodology.
