This paper presents considerations towards an information and control
architecture for future electric energy systems driven by massive changes
resulting from the societal goals of decarbonization and electrification. This
paper describes the new requirements and challenges of an extended information
and control architecture that need to be addressed for continued reliable
delivery of electricity. It identifies several new actionable information and
control loops, along with their spatial and temporal scales of operation, which
can together meet the needs of future grids and enable deep decarbonization of
the electricity sector. The present architecture of electric power grids
designed in a different era is thereby extensible to allow the incorporation of
increased renewables and other emerging electric loads.Comment: This paper is accepted, to appear in the Proceedings of the IEE
