摘要
Abstract
When traditional droop control is adopted for microgrids operating on isolated islands,it is impossible to achieve zero-diffe-rence control of bus voltage and frequency.Based on the theory of finite time consistency,it constructs a distributed collaborative control method for voltage and frequency.Firstly,by combining communication technology with the principle of hierarchical control,the system can achieve zero difference frequency modulation and voltage recovery while reducing the communication pressure between micro sources.Secondly,for the secondary control strategy,it considers the power supply ratio between micro sources to improve the efficiency of micro source utilization and avoid single point faults under centralized control mode.Finally,by building a simulation model of a multi micro source isolated microgrid,it verifies the rationality of the control strategy and the effectiveness of the secondary control strategy based on distributed consistency algorithm.It realizes the voltage compensation of the island microgrid,the no-difference regulation of frequency and the plug-and-play function of micro-sources,which improves the reliability and flexibility of the system.关键词
