Research Status of Residential DC Microgrid Power Supply Technology
摘要
Abstract
With the increasing of the capacity of distributed energy resources,the problem of power quality and power loss caused by distributed energy resources paralleling in the grid has become a big challenge,which can be effectively alleviated by applying DC supply in distribution networks.In recent years,because of the rapid development of power electronic technology and the significant improvement of work efficiency and rated capacity of AC/DC converter and DC/DC converter,the network loss of DC power supply system has been reduced.Meanwhile,the compatibility of household appliances with DC power supply has been improved,so the residential DC power supply technology will inevitably become the trend of research and development in the future.The research status of residential DC power supply technologies around the world were systematically reviewed,and the advantages and feasibility of these technologies were analyzed.Finally,a typical residential DC micro-grid model was proposed.The involved technical problems,such as the determination of voltage level,the choice of networking mode and the system protection and control were discussed in detail.Some prospects on the development of DC power supply technologies were also presented.关键词
