How can I solve a nonlinear model with DICOPT solver in Pyomo? Is this possible to use DICOPT solver through Neos for Pyomo?

You cannot use DICOPT solver in Pyomo, not supported. However, if your model is written in Pyomo then you can save it in gams format using model.write('mymodel.gms') then upload it to NEOS. Or open your model in GAMS Studio, select GAMS > Run NEOS - Short from the menu to automatically establish a connection with NEOS. In that case you can use GAMS demo without paying any license fees.
Nowadays, the Neos server only supports a small number of solvers through Pyomo. I may consider installing 'gams' with at least a demo license and call DICOPT from gams from Pyomo.
