CPS: TTP Option: Synergy: Collaborative Research: Hardening Network Infrastructures for Fast, Resilient, and Cost-Optimal Wide-Area Control of Power Systems
Project runs from 09/15/2015 to 08/31/2020
The objective of this 3-year NSF-CPS proposal is to address three fundamental research challenges required for transcending wide-area communication and control of the North American power grid from a mere optimistic vision to a sustainable reality. Following the US Northeast blackout of 2003 and the subsequent advancement of Synchrophasor technology over the past decade utility owners have gradually started to look beyond the traditional myopic approach of local output feedback and instead use wide-area measurement feedback. However, currently a huge gap exists between implementing such controls using of realistic communication networks in a reliable and economic way. Majority of the ongoing NASPI-net activities are devoted to the hardware architectural planning of aspects of wide-area communication with very little attention to how complicated MIMO control loops, when implemented on top of this communication, may perform under various operating conditions. The vision of this project is to underline the necessity of constructing such an integrated, robust and economically sustainable wide-area communication and control infrastructure by addressing three critical research challenges that stand in its way – namely, (1) understanding how distributed multi-input multi-output (MIMO) controllers dictate and depend on the operational rules of underlying communication systems, and how the two should be co-designed in sync with each other, (2) investigating how wide-area communication can be made economically feasible and sustainable via joint decision-making processes between participating utility companies, and testing how controls can play a potential role in facilitating such economics, and finally (3) exploiting new design ideas of software-defined networks (SDN) so that wide-area communication is not merely a data-transporter but also facilitates the closed-loop dynamic performance of the grid.
