DC Micro-grid——the Important Mode in the Field of Power Supply and Consumption

Abstract

Abstract:

Due to the extensive development of DC distributed generation, energy storage device, DC load and high requirement of power supply quality, DC micro-grid which is composed by DC sources, energy storage, loads and monitoring device, will become the important mode in the field of power supply and utilization in the future. Based on the analysis of driving force of DC micro-grid development, this paper summarizes the main features and topologies of DC micro-grid, and introduces the development scenario both at home and abroad. In addition, the key equipment for DC micro-grid is discussed. From the equipment and system level, the control strategies are investigated respectively. Then both the fault types and its protection are discussed. The further development and application prospect of DC micro-grid is forecasted in the end.

Key words: DC micro-grid, the field of power supply and utilization, topological form, coordination control strategy, fault protection
