摘　　要：针对直流微电网中的飞轮储能群组,提出一种基于一致性算法的双层分布式协同控制策略:一次控制层基于磁场定向控制和空间矢量脉宽调制算法,由电压电流下垂方程提供设定值;在此基础上加入分布式二次控制层,通过基于一致性算法的平均电压观测器和飞轮能量状态观测器,仅依靠相邻储能单体之间的通信实现对下垂控制的修正。该策略不仅能有效调节下垂控制导致的电压偏差,还能克服传统集中式控制存在的单点故障和扩展性受限的问题。仿真结果表明:所提策略可将各母线电压平均值恢复至额定水平,还可实现各飞轮储能单体按其能量状态分配功率,避免功率环流。A two-layer distributed cooperative control strategy,based on the consensus algorithm,is proposed for flywheel energy storage group within DC microgrids.The primary control layer adopts magnet field-oriented control and space vector pulse-width modulation,with reference values provided by voltage-current droop equations.Building upon this foundation of traditional droop control,an additional distributed secondary control layer is introduced.This layer incorporates an average voltage observer and a state equation relying on flywheel energy indicators.It solely utilizes communication between adjacent energy storage units to modify the droop control via the consensus algorithm.This approach effectively rectifies voltage deviations caused by droop control while overcoming issues associated with traditional centralized control,such as single-point failures and limited scalability.Simulation results affirm the effectiveness of the proposed strategy,demonstrating the restoration of average bus voltage to its rated level,the allocation of power to individual flywheel energy storage units according to their energy states,and the prevention of power circulation.
