add "capacity" terms #320

[0UmfHxcvx5J7JoaOhFSs5mncnisTJJ6q]

Add requested terms, as per discussion:

• power → power rating for energy converting devices
• power → declared net capacity for power plants, excluding own consumption
• power → nameplate capacity for power plants, including own consumption
• energy → storage capacity for energy storage objects

Close #320

so gross capacity/ generation would be an alternative term for nameplate capacity? Then it should be added as such.

[akleinau]

can you add the pull request link to the term trackers?

No. "Gross generation" is the amount of energy (measured in Joules) a power plant did produce over a given period of time. "Nameplate capacity" is the power rating (measured in Watts) that specifies how much the power plant could produce at any moment of time.

then this solves just part of #320 as the gross capacity class is not included. So the "closes #320" part should be taken out

Issue #320 ("Include 'Capacity' of energy system components") pertains to capacities (colloquial) as characteristics of energy system components. "Gross production" is not a characteristic of an energy system component, but an empirical fact. "Gross capacity" is not a characteristic of one energy system component, but of an aggregate of such components.
Both terms are beyond the scope of this issue.

I opened a seperate issue #394 for the gross generation/ gross electric output discussion.
It references #320, so nothing gets lost, when this PR closes the issue.

On second thought I'm not sure anymore if a "maximum energy" actually is a subclass/type of energy like chemical or electrical energy. I think it's rather a subclass of the soon to be introduced "quantity value" class - a number together with a quantity.
@jannahastings what do you think?

[jannahastings]

Yes -- "maximum" is a kind of a mathematical operation, so it makes sense that it would be associated with an output that is a quantity value and be about, rather than a subtype of, energy.

[akleinau]

I implemented them now as quantity values, changing the definition to:
"... is the quantity value stating ..."

eg: "Power rating is the quantity value stating the maximum power an energy converting device can convert."

@0UmfHxcvx5J7JoaOhFSs5mncnisTJJ6q can you review my changes please?

[akleinau]

I'll merge this bc of the release soon
