Please start a new thread, don't piggy back on an unrelated one.
Please provide a complete, readable minimal example. This is simply
unreadable. The data is incomplete. The query and the results don't
correlate.
Looking at:
> "vars": [ "id" , "name" , "bVol" , "aVal" ]
but
> select ?id ?name ?bvId ?res ?analog ?analogValue ?id2 ?aVal
so the results do not correspond to the query.
The second OPTIONAL in the query is not connected to anything by a
variable as far as I can see.
After that, I'm simply lost as to what the question is about.

(cim:AnalogValue.value --- I want to query these values related to
cim:Measurement.PowerSystemResource). Actually, I do not know how to do
this kind of SPARQL query. I just put 'somethings' (colored with light
green) tried to query aVal (cim:AnalogValue.value).
