Resilience enhancement in the planning of medium-and low voltage power distribution systems with microgrid formation

A resilience enhancement approach applied to medium- and low voltage (MV/LV) systems planning is proposed. In the mathematical model formulation, substations, distribution transformers, cables, switches, renewable generators, and batteries are taken into account. In the resilience planning approach, renewable generators and batteries are able to operate isolated from networks through microgrids formation. Numerical results, applied to an MV/LV distribution system, show that non-supplied energy costs are lower when techniques to increase network resilience are considered.
