Advancements in generalized immittance based stability analysis of DC power electronics based distribution systems

Stability is an important design consideration in power electronics based power systems such as those on electric ships. Generalized immittance based stability analysis is one approach to addressing this design consideration. In this paper, refinements to the generalized immittance based stability analysis approach are proposed. This include the introduction of Root Exponential Stability Criterion which offers improved numerical robustness, and an admittance allocation algorithm which can be used to formulate admittance specifications on the individual loads on a common bus.
