Subject: RE: [emix] Groups - microgrid_summary.pdf uploaded
To your points, my comments: 1. architecture (some propose decentralized peer-to-peer coordination,
others expect centralized hierarchical control) I don’t think this matters to EMIX (or IMO to microgrid). What
you do inside your virtual end node (or whatever we are going to call it) is up
to you. EMIX is about getting you the price signal. Or does the required signal
somehow need to be different depending on your control paradigm? I don’t see
that. 2. two-way or one-way power flow (some proposed a single direction of power flow,others
proposed the microgrid for ancillary services) EMIX assumes 2-way is possible, whether you use it or not. 3. size (some propose a microgrid should be less than 1MW, others
have no restrictions on generation capacity) This is semantics about the term “microgrid”, nothing to do with
EMIX, unless we specifically use the term within the standard. I guess we
should not in any formal way. 4. connection points (some proposed only a single connection point, others
assumed more of a decentralized integration/connectivity) Do you mean electrical connection or communication connection? David -----Original Message----- The document named microgrid_summary.pdf has been
submitted by Anne Hendry to the OASIS Energy Market Information Exchange (eMIX) TC
document repository. 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 there. 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) -Anne View Document Details: http://www.oasis-open.org/committees/document.php?document_id=37277 Download Document: http://www.oasis-open.org/committees/download.php/37277/microgrid_summary.pdf PLEASE NOTE: If the above links do not work for you,
