LVDC rules – technical specifications for public LVDC distribution network

Abstract

When a low-voltage (LV) DC distribution system installation is realised in a public power distribution network, an extensive specification is required to ensure electrical and equipment safety and compatibility between the existing grids and customer-end installations. The goal of the study is to give to a reader an understanding what is required for safe and reliable operation of the LVDC distribution in an actual distribution environment. The study discusses the mechanical and electro-technical aspects of the pilot installation. The focus is on the common system and power electronics specifications.
