> Document Description:
> To try to wrap up the microgrid definition discussion I've captured in this
> document the the most prevalent characteristics from previous posted
> sources -- by no means an extensive set, but just enough to get a sampling
> of the diversity of thinking in the area to help determine what is in scope
> for EMIX -- and marked similarities and areas of
> contradiction/divergence.
>
> Characteristics that were common to most definitions are in green and what
> I perceive as contradictory characteristics (they offer a view that is
> contradictory to another view) are in red -- both open for discussion. If
> none of the red characteristics are of a concern to EMIX, we can discard.
> For the rest (green and black) we should decide if they are drivers for
> EMIX (in scope) or not, and if so, make sure we've included support for
> those features/capabilities in the spec.

> The microgrid concept seems to span the breadth from literal physical
> islands to virtual power plants and community choice aggregators, each with
> their own scenarios for energy generation and distribution. The areas of
> agreement are the more common concepts of you can expect (DER, better
> efficiency, economics, source diversification, etc). Not much contention

> Areas of contradiction appear to revolve around these four topics:
>
> 1. architecture
>
(some propose decentralized peer-to-peer coordination,
>
others expect centralized hierarchical control)
> 2. two-way or one-way power flow
>
(some proposed a single direction of power flow,
>
others proposed the microgrid for ancillary services)
> 3. size
>
(some propose a microgrid should be less than 1MW,
>
others have no restrictions on generation capacity)
> 4. connection points
>
(some proposed only a single connection point,
>
others assumed more of a decentralized integration/connectivity)
