Abstract
With the development of power electronics in most customer appliances, DC grids may prove to be an interesting alternative to the usual AC grids in a near future. This paper provides a first set of results for various settings of LV grids in the prospect of investigating new architectures for grid planning: full-AC, hybrid AC/DC and full-DC variations are considered for a same LV grid with solar panels, decentralized storage units and electric vehicles connected. Each grid architecture is compared on the basis of technical aspects, especially losses and voltage drops, for different operation points. Usual electric planning tools are currently quite limited in regards to such hybrid networks, making it difficult to assess non-conventional planning strategies. We use here the Modelica Electric Power System Library (EPSL) developed by Dassault Systèmes and extended in a joint work with EDF in order to tackle this issue and perform an evaluation of the grid architectures.
