Description

The underlying use case is to make it easier to run analyses that combine meter readings with network models

One metering device can provide energy, RMS and many other variables for single point in the network, or for containers like a substation.
The protocol could be IEC 61850 or COSEM or something else
There are two choices for mapping these variables
1. Via Measurement: Equipment and Terminal are explicitly defined
2. Via Metering Usage Point: Terminal is implied by associated Equipment
This unambiguous for an EnergyConnection = DER
But it is ambiguous for branch devices e.g. supplying a Campus; or summary metering e.g. for a substation

Proposal: use same associations as Measurement
Deprecate UsagePoint -> Equipment
Add UsagePoint -> PowerSystemResource
Add UsagePoint -> ACDCTerminal
