Autonomous Resilient Grids in an IoT Landscape Vision for a Nested Transactive Grid

A vision for an autonomous power grid as an Internet of Things is presented. This vision encompasses the functionality from system operations and market operations perspectives. The vision aspires to a transactive energy grid with intelligence distributed among all components. It introduces the concept of a nested transactive grid to model the distribution grid as a nested set of virtual microgrids that can each act as a market. This facilitates exchanges, including peer-to-peer, participant-to-market, and market-to-market while incorporating the security of the grid. The vision allows to exploit the proliferation of DERs and flexible demands to realize a more resilient grid in both normal and emergency conditions utilizing the transactive grid capabilities. An architecture of the proposed nested model and orchestration of the interactions among the markets are described. A practical use case is also presented.
