Abstract

As a key technology for the development of the new electric power system, low-voltage DC power distribution is gradually proceeding from theoretical research to engineering demonstrations and then penetrating to commercial applications. In this paper, a survey of the low-voltage DC distribution network is conducted from the perspective of the engineering practical application. The technical analysis of the topological structure, cooperative control strategy and fault protection is compared. An optimized design was performed for a low-voltage DC application in Xiong'an New Area that was successfully applied in the practical project. The scheme validation was completed by using the statistical analysis for the actual operating conditions, which provides practical experience in the development and construction of the low-voltage DC distribution networks.
