Stability-constrained design for low voltage DC microgrids
… DC microgrids as a result of tightly controlled loads in the presence of inductive delays. First, we examine the instability that arises when a constant power load is added to or removed from a network where the topology is unknown. While removing the dependence of the stability certificate on …
