Changes in models
[Beta 1]
ggzone Introduced mean exhaust temperature to fix issue with Energy balance
PVstrModOpt Bug fix for power and voltage calculation
PVstring Moving MPPT to separate function for PVstring and PVstrModOpt
Removing number of bypass diodes calculated in optimization from voltage calculation, using
negative voltage directly instead.
Removing unnecessary irradiance check in voltage calculation, unifying handling + bug fix of
bypass diode.
PVmicroInv Update PVmicroInv to not use DiodeFC/SH/HF functions, instead same optimization as in PVstrModOpt.
Adding diode index calculation for handling of bypass diodes with multiple submodules in parallel.
[Beta 2]
PVmicroInv Correcting wrong variable description
PVstrCellOpt Support for lumped model and parallel submodules
PVstrModOpt Adding floor to integer division to avoid problem where intermediately calculated value being
PVstring non-integer prevents from switching from lumped to non-lumped parametrization.
Update pv models to have one diode parameters directly in models rather than database
- DiodeFC Removed PV models that are no longer used (previously used by pvmicroinv)
