Optimal Control Design for Operating a Hybrid PV Plant with Robust Power Reserves for Fast Frequency Regulation Services

no code implementations7 Dec 2022 Victor Paduani, Qi Xiao, Bei Xu, David Lubkeman, Ning Lu

The controller's objective is to control the PV and BESS to follow power setpoints sent to the the hybrid system while maintaining desired power reserves and meeting system operational constraints.

Feeder Microgrid Management on an Active Distribution System during a Severe Outage

no code implementations23 Aug 2022 Valliappan Muthukaruppan, Ashwin Shirsat, Rongxing Hu, Victor Paduani, Bei Xu, Yiyan Li, Mesut Baran, Ning Lu, David Lubkeman, Wenyuan Tang

The management of such feeder-level microgrid has however many challenges, such as limited resources that can be deployed on the feeder quickly, and the limited real-time monitoring and control on the distribution system.
