Optimizing DER Aggregate Flexibility via Network Reconfiguration
Feixiang Zhang, Hongyi Li, Bai Cui +1
The aggregate flexibility region of distributed energy resources (DERs) quantifies the aggregate power shaping capabilities of DERs. It characterizes the distribution network's pot…
Synchronization-Safe Dynamic Microgrid Formation for DER-Led Distribution System Restoration With Constraint-Aware Graph Learning
Cong Bai, Salish Maharjan, Yunyi Li +2
Prolonged blackouts in distribution systems (DSs) with high penetration of distributed energy resources (DERs) necessitate novel restoration strategies to rapidly restore loads. Ho…
Exploiting Convexity of Neural Networks in Dynamic Operating Envelope Optimization for Distributed Energy Resources
Hongyi Li, Liming Liu, Yunyi Li +1
The increasing penetration of distributed energy resources (DERs) brings opportunities and challenges to the operation of distribution systems. To ensure network integrity, dynamic…
Learning to Mitigate Post-Outage Load Surges: A Data-Driven Framework for Electrifying and Decarbonizing Grids
Wenlong Shi, Dingwei Wang, Liming Liu +1
Electrification and decarbonization are transforming power system demand and recovery dynamics, yet their implications for post-outage load surges remain poorly understood. Here we…
Underground Power Distribution System Restoration Using Inverter Based Resources
Wenlong Shi, Hongyi Li, Zhaoyu Wang
Underground power distribution systems (PDSs) are increasingly deployed in urban areas. The integration of smart devices including smart switchgears, pad-mounted distribution trans…
Situationally Aware Rolling Horizon Multi-Tier Load Restoration Considering Behind-The-Meter DER
Wenlong Shi, Junyuan Zheng, Zhaoyu Wang
Restoration in power distribution systems (PDSs) is well studied, however, most existing research focuses on network partition and microgrid formation, where load transfer is limit…
