Advantages and challenges in promoting modern 400-V DC distribution networks with integrated renewable energy resources

Abstract

Motivated by recent developments of renewable energy resources and the smart grid, a 400-V dc distribution network has a potential to replace the traditional ac distribution network, and to provide high energy efficiency and advanced controllability, protection, sustainability and reliability in the power system. Therefore, in this paper, the advantages of efficiency gain and energy saving are discussed and demonstrated by a case study of a 400-V dc distribution network. Related theoretical analysis in efficiency gain is proven by simulation tests and experiments. The challenges are identified for promoting 400_V dc distribution, in the aspects of stability, protection, and security. Possible solutions for these three challenges are discussed, which may lead to future research focuses.
