Abstract
The DC technology appears as promising in enabling new advanced microgrids. The reason is to be sought in the distributed implementation of PV renewable energy sources and battery storage systems, which actually operate by a DC distribution. When a widespread use of power converters guarantees the DC microgrid’s functionality, an attentive evaluation is to be carried out on the DC stability matter. The present chapter wants to investigate the methods to assess the stability in isolated DC distribution systems. As the latter can be lost when high are the converters’ control bandwidths, analytical developments are proposed to correlate requested control performance and poles positioning. If the methodology is initially conceived for a classical DC radial distribution, a final study will transfer it on complex DC Zonal Electrical Distribution Systems.| File | Dimensione | Formato | |
