Abstract
Due to low inertia and constant power loads, stability is a major issue for dc distribution grids. Previous research focuses mostly on the (mathematical) analysis of the stability, but does not provide any guidelines to ensure stability. This paper presents four guidelines that ensure the existence of an appropriate equilibrium and stability around that equilibrium. From a linearized model of the dc distribution grid the location of the equilibrium and the stability of the system are derived. Subsequently, guidelines for the existence and propriety of the equilibrium, and the static and dynamic stability around that equilibrium are developed. Furthermore, the accuracy of these guidelines is determined. Additionally, possible applications of the guidelines are discussed.
