THE SUBSTATION OF THE FUTURE WILL MOVE AWAY FROM THE
current single-purpose, hardware-based protection and automation systems and replace them with a software-defined control system running
virtual services: a digitally enabled substation. This is necessary to enable
substation systems to adapt to the new reality of an increasing amount of
inverter-based distributed energy resources (DERs) changing operating
requirements and affecting feeder power flow, voltage, and protection
functions. Wind power, solar power, battery storage, and electric vehicles
(EVs) may be connected anywhere to the grid. Unless operation is coordinated, the geographic concentration of DERs by different owners could
potentially result in a negative impact to the existing grid.
Future power system control is likely to be more cooperative and negotiated because operators and control functions will have to plan for and quickly
adapt to changes in available resources and power flows. Transmission and
distribution planners, engineers, and asset managers will need information
