摘要：
In order to solve the problem of distributed energy generation, microgrid has been proposed as one of the options. Compared with AC microgrid, DC microgrid is more suitable for many distributed power equipment. In order to ensure the stable operation of the DC microgrid, it is necessary to develop a set of effective energy management strategies. How to solve the problem of current sharing in the bottom control of the energy management has become the key to implementing the reliable operation of each component unit in DC microgrid system. The droop control is widely investigated and discussed as a typical method of implementing current sharing. Due to the inherent limitations of the traditional droop control, compensations brought by the secondary control are required to improve the overall performance. In this paper, different droop control methods were systematically classified and analyzed. Finally, the technical characteristics of various droop control were compared and summarized, which can provide references for the further research and development of this field. © 2018 Chin.
