Aaron Snyder  commented on EMIX-285:
------------------------------------

Recommend changing "Definition" of VMin to "voltQuantity" (this keeps a voltage from having a 'var' definition)
Recommend changing to "Note" of VMin to "The minimum voltage level of the Voltage Regulation Service. In IEEE 1547, this represents a voltage level of 88% of nominal voltage for a photovoltaic (PV) inverter." (presumption is that there are voltage regulation services available that are not PV-related and that the IEEE citation is an example)
Recommend changing "Definition" of VMax to "voltQuantity" (this keeps a voltage form having a 'var' definition)
Recommend changing "Note" of VMax to "The maximum voltage level of the Voltage Regulation Service. In IEEE 1547, this represents a voltage level of 110% of nominal voltage for a photovoltaic (PV) inverter."  (presumption is that there are voltage regulation services available that are not PV-related and that the IEEE citation is an example)
Recommend changing "Note" of QMax to "Maximum reactive power available for voltage regulation services. Note this is not the maximum reactive power of the voltage regulation service resource. Note this may be a positive (capacitive) value or negative (inductive) value."

> End of explanation of QMax states "Qmax is the inverter's current var capability and may be positive (capacitive) or negative (inductive). It would be the VA capability left after supporting the W demand."
> The final sentence is not at all clear, and the voice is not that of a definition ("...it would be.." should perhaps be "it is...". And what is "the W demand"?
