2022 article

Optimal co-designs of communication and control in bandwidth-constrained cyber–physical systems

Negi, N., & Chakrabortty, A. (2022, May 11). Automatica, Vol. 8.

By: N. Negi n & A. Chakrabortty n 

author keywords: Linear optimal control; Structural optimization; Time-delay systems; Delay analysis; Bandwidth allocation
topics (OpenAlex): Stability and Control of Uncertain Systems; Energy Harvesting in Wireless Networks; Sparse and Compressive Sensing Techniques
TL;DR: This work addresses the problem of sparsity-promoting optimal control of cyber-physical systems (CPSs) in the presence of communication delays by co-designing an optimal combination of these two delays and a sparse state-feedback controller while respecting a given bandwidth cost constraint.

author keywords: centralised control; power distribution faults; distributed power generation; distributed control; power distribution control; distributed control; power sharing strategy; islanded AC microgrid; novel secondary control strategy; radial microgrid; end-to-end distributed energy resource interconnections; islanded conditions; sparse communication; centralised controller; distributed algorithm; desired power injection; DER bus; load change; remaining task; bus angle set points; DER units; actual power injections; accurate system wide power injection; respective DER base ratings; three-bus; three-DER system; microgrid ratings; system nominal ratings; correct power injection solution; accurate power
topics (OpenAlex): Microgrid Control and Optimization; Smart Grid Energy Management; Optimal Power Flow Distribution; Islanding Detection in Power Systems
TL;DR: This study presents a novel secondary control strategy for a radial microgrid with end-to-end distributed energy resource (DER) interconnections, operating under islanded conditions, which utilises sparse communication and precludes the presence of a centralised controller.
