Study on Multiple Hierarchical DC Micro-grid Based on Photovoltaic Generation Systems

摘要：

　　Micro-grid is suitable for popular utilization of distributed renewable energy generations.It can save grid-connected photovoltaic inverter and some rectifiers for DC loads when connecting photovoltaic generation to local loads by DC micro-grid,and the energy use efficiency increases dramatically.This paper proposed a multiple hierarchical DC micro-grid based on photovoltaic generations.The photovoltaic generations dispersed in different building roofs can be mutual backups while contacting them through DC micro-grid,and the energy storage devices have an easy access to connect in different forms,improving the system reliability and reducing the construction cost.
