摘要
DC microgrids(DCMGs)integrate and coordinate various DC distribution generation units including various renew-able energy sources and battery storage systems,and have been used in satellites,the International Space Station,telecom power stations,computer power supplies,electric aircraft,and electric ships.However,the presence of constant power loads(CPLs)can cause instability in DCMGs.Thus,this paper reviews the stabilization techniques that can resolve instability caused by CPLs,as well as various parameters of CPLs,such as bandwidth,and the frequency of the CPLs that can stabilize the DCMGs.It also discusses recent trends and future work in finding stability limits using the parameters of CPLs.It should be useful for directing research towards appropriate mathematical and experimental approaches for the stability of DCMGs with CPLs.
