Research on Improving Droop Control Strategy of DC Microgrid
摘要
Abstract
The DC microgrid is a new type of grid structure composed of distributed power supply and energy storage,and its control strategy is one of its key technologies. The traditional droop control strategy has the problem of inaccurate power distribution and needs improvement. Firstly,the characteristics of the parallel distributed power supply from the traditional droop control strategy were analyzed,and the defects of the traditional droop control were pointed out. Secondly,the strategy of improving the droop control was put forward,and by adding the power distribution and sagging coefficient,the distributed power between the power distribution was realized,and the control performance was improved. Finally,the corresponding simulation model was built in Matlab/Simulink,and the proposed control strategy is verified,the improved droop control strategy with accurate power allocation performance is verified.关键词
