Extensibility

An architectural characteristic that takes the future extension of System functions and capabilities into consideration. It is a systemic measure of whether the Systems Architecture choices made or inherited are capable of supporting the extension of System functions and capabilities, including the level of effort needed to implement the extension.

In the context of a Power System experiencing significant transformation, extensible architectural and technology choices aim to be:

  1. Cognisant of the plausible future developments that the solution will need to enable or migrate toward;
  2. Capable of accommodating future requirements without impairing core, critical functionality; and,
  3. Capable of enabling cost-effective migration to longer-terms solution when required.

Given the fast-evolving nature of power system transformation, the Future Grid Accelerator (FGA) has the status of a perpetual BETA version. Your suggestions for how each concept and definition may be enhanced are very welcome.

All feedback will be reviewed and considered for inclusion in subsequent updates.
