【Abstract】 The rapid development of integrated energy system is of great significance to solve energy and environmental problems. And with the development of LVDC power supply technology, the district level LVDC supply integrated energy system(DLVDC-IES) is expected to become the optimal solution for energy supply at the district level. In this paper, the key technologies and research status of the DLVDC-IES are analyzed and summarized from the aspects of system modeling, source charge prediction and planning operation. Based on the research progress and development trend of related technologies, the key problems that need to be solved in modeling and optimization of the DLVDC-IES are analyzed, and the future research direction is forecasted.更多还原
