Renewables
- Load centre 1 - the load centre variables can be useful for varying the number of PV panels in a study. Set up and select a number of load centres each one having a different number of PV panels.
- Load centre 2
- Load centre 3
- Load centre 4
- Load centre 5
Other
- Zone capacitance multiplier
