RSYS.znLoad[0] is often slightly different from RSYS.outSenTot

[nealkruis]

These expressions should(?) result in zero difference when the setpoint is met:

max(0, @RSYS["<%= system_name %>"].znLoad[0])*@Top.subhrDur - @RSYSRES["<%= system_name %>"].S.qhNet

min(0, @RSYS["<%= system_name %>"].znLoad[0])*@Top.subhrDur - @RSYSRES["<%= system_name %>"].S.qcSenNet

I wonder if this is an iteration issue where znLoad needs to be updated one last time after the supply has been set?

Also should improve documentation of what znLoad[*] means. It is more of a system load (since it includes distribution losses).

Can you provide cse file(s) that exhibit this issue? I could not reproduce using regression test file perfmap.cse.
