What are the cause of the infeasibility ?

Hello All, i am working on an optimization problem to maximize an objection function in power system load flow MINLP problem using BONMIN solver. Unfortunately the below message appears when the running process is finished: EXIT : Converged to a point of local infeasibility. Problem may be infeasibl...

Load Flow of 33 buses distribution system, current in between buses equal zero

I Have a problem using GAMS in load flow modelling on 33 buses distribution system, The problem is that when I display the values of the current in between buses C(I,j,t) after running it gives me all zeros and all voltages equal 1, why the voltage values are fixed at all buses and why the current a...

Constraints Violation in load flow model

Hello All, I have an electrical low flow problem using 33 bus distribution system, my objective function is to maximize the installed renewable capacity Wcap(i) at certain buses namely 6,12,18 and 33 following certain demand pattern w1& w2. eq15 .. OF=e=sum((i),Wcap(i)* Sbase); solve loadflow maxmiz...

the solver found no feasible solution

Hello all, I am now working to build the model a published paper using GAMS. I successfully went through all the error messages appeared while developing and running the model and all have been resolved, now the model works with no error but unfortunately the solver found no feasible solution. I don...
