This paper studies stability analysis of dc microgrids with uncertain constant power loads (CPLs). It is well known that CPLs have negative impedance effects, which may cause instability in a dc microgrid. Existing works often study the stability around a given equilibrium based on some nominal values of CPLs. However, in real applications, the equilibrium of a dc microgrid depends on the loading...
The forecast data of the renewable energy generation and loads cannot be exactly accurate because of their intermittence and fluctuation characteristics. To handle this problem, a probabilistic chance-constrained model for day-ahead scheduling is proposed in this paper. The proposed model is established not only by the aggregated scenarios but also by the eliminated ones which are used in chance constraints...
