Energy Broadcast System: Multi-Rate Analysis for Improved Situational Awareness
Abstract
Electric power distribution systems directly interconnect sources and load for critical safety and quality of life services. This h,olds true in both terrestrial and shipboard power systems. Modernization of electric power distribution systems has seen the prolif,eration of electronically controllable loads (motor drives, etc.,) and more recently, active impedance networks. In addition, to sup,port terrestrial distribution energy management systems, select utilities have constructed heterogenous, dedicated communication net,works to support power distribution automation and control. It is envisioned that shipboard communication networks should be designe,d to support secure, power and energy functions.The uncertainty with respect to electric power usage and communication network perfo,rmance challenge traditional adaptive, but fixed rate time analysis approaches stemming from terrestrial systems. This work proposes, multi-rate analysis that is driven by power electronic power distribution system uncertainties which include the embedded communica,tion systems. The research problem will be driven by forecast uncertainties in shipboard energy usage scenarios with a focus on risk, to electric power static security constraints. As a consequence, corrective control will be naturally embedded, if necessary.The p,roposed approach is to address power electronic power distribution systems (PEPDS) with uncertainty through multi-rate analysis and,control. Multi-rate approaches will enable the capture of both probabilistic, risk-based uncertainty as well as data-driven interde,pendent uncertainties. The proposed work seeks to expand classical model predictive control frameworks which typically utilize fixe,d time windows within a stated time horizon. A multi-rate environment will allow for supervisory control to be enacted at targeted t,ime grains based on the systems need. Towards this end, three main technical objectives are identified and will categorize the pro,posed work. 1: Inclusion of Uncertainty Within Temporal Simulation Parameters2: Inclusion of Uncertainty Within Spatial Simulation M,odels3: Development of Software Application Tools and Hardware EmulationsSpecific tasks will address PEPDS and their embedded commun,ication and control systems.The completion of this work would enable targeted, risk-based monitoring of shipboard power systems. Th,is, in turn, would support subsequent optimal control techniques for improved planning and operations. In particular, contingency an,alysis and automated service restoration efforts would benefit. Our specific vision is that the work would support an Energy Broadca,st System that informs command and naval personnel of the current energy condition of the power system and the predicted energy cond,ition level based on both measurement data and forecasted energy needs.
