CIM Issues #7009

The MR suggests adding the EnergyCharacteristics class to MarketManagement and associate it with Series and MarketEvaluationPoint. See furhter attached PDF file.
Additional background from 6745 issue for consideration:
Additionally, I recommend we add a direction to the Grid Service as a separate field. Many resources can provide one one "side" of the delivery, for example a load may be able to provide energy reduction (demand response), but not energy increase. Rather than separate out each grid service, and enumeration called gridServiceDirection could be used with the following:
- BiDirectional
- Injection
- Withdrawal
- Increase
- Decrease
I suggest the two "flavors" because some products naturally make sense with one and not the other. For example, Voltage Increase makes sense but not really Voltage Injection. Energy, on the other hand, makes sense ash Energy Injection and less so (although not entirely with Energy Increase) - I think worth a debate. I do recommend against anything which can be viewed differently from the grid and customer perspective, like "import" and "export" or "in" and "out". A battery might export to the grid, but the grid operator is importing power from the customer. These "which side of the meter am I sitting" issues can lead to confusion and errors in exchanges.
If this idea is not popular, we can always revert back to triplicating each service, e.g. RampingUp, RampingDown, and Ramping (for the case where the service requires both directions and does not differentiate pricing based on direction).
We also need to consider similar constructs already established, of which there are more than I expected:
- flowDirection (string)
- FlowDirectionType (enumeration 'forward' and 'reverse')
- FlowDirectionKind (large enumeration focused on real/reactive power quadrants)
- RelativeDirectionKind (enumeration 'up','down','upAndDown' and 'none')
- BidDirectionKind (enumeration 'up', 'down', 'upAndDown' and 'stable')
- ScheduleKind (enumeration 'generation', 'load', 'loadIncrease', 'loadDecrease', and soon 'genrationIncrease' and 'generationDecrease')
- ComDirectionKind (enumeration 'fromDevice', 'toDevice', and 'biDirectional')
This last one is close to what I propose, but is awkward to use with the "Com" in front. But it does sorta make sense with the service coming from the device and/or going to the device, so I could see us using that with service; although the natural use would rather be 'fromResource' and 'toResource'
