Hierarchical Control Strategy for DC Microgrid Clusters
摘要
Abstract
A hierarchical control strategy is proposed in this paper for the stable operation of DC microgrid clusters.Un-der the primary control,all the sub-microgrids operate independently and stably,the distributed generations(DGs)are under the maximum power point tracking(MPPT)control,and the allocation of load power is dynamically adjusted by the storage system to realize a state-of-charge(SOC)balance among storage units.Under the secondary control,seam-less switches among different operation modes of microgrid clusters are controlled according to the bus voltage in each sub-microgrid,and the bus voltage quality is improved through managing the power flow among sub-microgrids.Final-ly,a microgrid clusters simulation model is built in Matlab/Simulink,and simulation results indicate that the proposed control strategy can improve the stability of microgrid clusters and the voltage quality of power supply.关键词
