Architecture
How the market, system operator, networks and participants fit together.
Architecture
The architecture combines several layers:
NEM wholesale dispatch
AEMO centrally dispatches the bulk power system at five-minute intervals.
Regional settlement
Wholesale prices are based on regional reference prices rather than nodal settlement.
Transmission constraints
Detailed transmission constraints influence central dispatch.
Distribution access
Distribution networks increasingly calculate dynamic operating envelopes or flexible connection limits.
DER optimisation
Households, businesses, aggregators and virtual power plants can optimise within communicated limits.
The defining feature is therefore the separation of energy-market value from local network-access feasibility.
