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…
Day-Ahead Offering for Virtual Power Plants: A Stochastic Linear Programming Reformulation and Projected Subgradient Method
Weiqi Meng, Hongyi Li, Bai Cui
Virtual power plants (VPPs) are an emerging paradigm that aggregates distributed energy resources (DERs) for coordinated participation in power systems, including bidding as a sing…
Unified Sensitivity-Based Heuristic for Optimal Line Switching and Substation Reconfiguration
Zongqi Hu, Weiqi Meng, Bai Cui
Optimal transmission switching (OTS) determines which transmission lines to remove from service to minimize dispatch costs. Unlike topology design, it alters the operational status…
DER Day-Ahead Offering: A Neural Network Column-and-Constraint Generation Approach
Weiqi Meng, Hongyi Li, Bai Cui
In the day-ahead energy market, the offering strategy of distributed energy resource (DER) aggregators must be submitted before the uncertainty realization in the form of price-qua…
