Abstract
In allusion to problems such as slow voltage dynamic response speed and unbalanced voltage of control strategy for the energy storage device in coping with power fluctuation and unbalanced load, this paper presents an improved droop control strategy.The strategy firstly adopts a calculation method for positive and negative sequence components based on complex filter to decompose voltage into positive and negative sequence components on the αβ axis so as to improve control effect of unbalanced voltage.Secondly, by using dual loop control based on quasi-proportional differential resonance control, it can guarantee response speed of output voltage of the energy storage converter.Verified by MATLAB/Simulink program, the improved droop control strategy can effectively shorten voltage recovery time and compensate unbalanced voltage.It can be taken as an effective way to improve system stability and realize peak-load shifting so as to enable energy storage technology apply in power distribution network more and more widely.关键词
