Passivation of Clustered DC Microgrids with Non-Monotone Loads
arxiv(2024)
摘要
In this paper, we consider the problem of voltage stability in DC networks
containing uncertain loads with non-monotone incremental impedances and where
the steady-state power availability is restricted to a subset of the buses in
the network. We propose controllers for powered buses that guarantee voltage
regulation and output strictly equilibrium independent passivity (OS-EIP) of
the controlled buses, while buses without power are equipped with controllers
that dampen their transient behaviour. The OS-EIP of a cluster containing both
bus types is verified through a linear matrix inequality (LMI) condition, and
the asymptotic stability of the overall microgrid with uncertain, non-monotone
loads is ensured by interconnecting the OS-EIP clusters. By further employing
singular perturbation theory, we show that the OS-EIP property of the clusters
is robust against certain network parameter and topology changes.
