Research on the Morphological Development of New Distribution Networks

The rapid development of smart grids has put forward new requirements for distribution grids, and the new distribution grids must make breakthroughs in solutions to distributed energy consumption, distribution equipment interconnection and new customer service infrastructure. This paper summarizes the development needs of new distribution networks, compares the current status of medium voltage distribution networks in Japan, Singapore, Paris and China. In the light of the development process of power systems from individual microgrids to microgrid clusters, from electric energy dominance to multi-energy coordination and complementarity, and from traditional rigid switches to flexible interconnection devices, we describe the morphological characteristics and key technologies of new distribution networks such as distributed microgrids, distribution networks with integrated multi-energy production and marketing, and honeycomb distribution networks based on new power electronics. Hopefully, this paper can provide references for the development and construction of future distribution networks.
