The restoration of power systems following a partial or complete shutdown has traditionally depended on large synchronous generators
capable of blackstarting the grid. However, with the increasing integration of renewable and distributed energy resources,
conventional blackstart strategies must evolve. These resources are able to reenergize power grids, but possess comparatively
low power ratings. This paper analyses the applicability of a concurrent inverter-based grid restoration strategy to distribution
grids, where several inverter-based units perform a soft energization of the grid concurrently, that is, ramping up at the same time,
instead of the traditional sequential approaches. The impact of delays, inverter location and different ramp behaviour from each
inverter are explored, and several solutions are proposed.
