Distribution System Flexibility Characterization: A Network-Informed Data-Driven Approach
Qi Li, Jianzhe Liu, Bai Cui +2
A distribution system can flexibly adjust its substation-level power output by aggregating its local distributed energy resources (DERs). Due to DER and network constraints, charac…
Ensuring Transient Stability with Guaranteed Region of Attraction in DC Microgrids
Jianzhe Liu, Yichen Zhang, Antonio J. Conejo +1
DC microgrids have promising applications in renewable integration due to their better energy efficiency when connecting DC components. However, they might be unstable since many l…
Optimal Power Flow for DC Networks with Robust Feasibility and Stability Guarantees
Jianzhe Liu, Bai Cui, Daniel K. Molzahn +3
With high penetrations of renewable generation and variable loads, there is significant uncertainty associated with power flows in DC networks such that stability and operational c…
Robust stability analysis of DC microgrids with constant power loads
Jianzhe Liu, Wei Zhang, Giorgio Rizzoni
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 insta…
