In my electricity generation module:

These are the exogenous capacity of the processes(no endogenous capacity):

The capacity of hydropower and biomass are both constant. Wind and solar power's capacity both grow linearly. The capacity shown in result view is the same.

And the maximum availability of the processes remain unchanged in simulation years:

Renewable processes have prior dispatch order, so they should be running at their maximum availability:

and the electricity output of biomass and hydro descends strangely:

Also solar and wind power's output have inflection points in their growth:

So why are renewable processes not working at their maximum availability? ಥ_ಥ

Thank you very very much!!!!

by the way can I get direct help online(zoom etc) anywhere? thank you!

Please check the availability shapes of your renewable resources and then demand. If demand is increasing and shape is accurate, then play with availability of thermal power plants and a constraint of maximum utilization may be added.

Hope this will resolve the issue

We usually set the constant value of Maximum Availability for the electric power technologies. So I'd suggest to set the constant values for wind and solor power. In the meantime, the result is related to the demand module. Hope this helps.
