Distribution Grid Services Performance Analysis for Cyber-resilient Online Feedback-based DER Control.

This paper investigates the influence of message delayed or lost on the performance of grid services controlled by an online cyber-resilient feedback-based Alternating Direction Method of Multipliers (ADMM) algorithm for Distributed Energy Resources (DERs). The proposed algorithm employs measurements of voltage magnitude and feeder head power as feedback to regulate grid services, including voltage regulation and head power tracking. Its remarkable resilience to measurement signal loss and dual variables data loss in the uplink and downlink directions makes it well-suited for practical implementation. Through rigorous experimentation on the IEEE 37 test system and actual data, we comprehensively assess the impact of data loss on the efficiency and reliability of various grid services. Our findings demonstrate the algorithm’s robustness under diverse data loss scenarios, showcasing its potential to enhance grid service performance even amidst challenging conditions. These results provide valuable insights for system designers and operators, enabling the seamless integration of renewable energy resources and bolstering overall grid resilience.
