Since, I research on rural electrification, for establishing the relations of different energy resources and better visual appearances; I am looking for a software.
It depends on what you want to simulate. If you are going to simulate a power system including renewable energy sources (RESs), MATLAB Simulink especially the power system toolbox could be helpful. But for economic evaluation goals and capacity sizing of RES, HOMER is a good choice. See the link below.
The HOMER software is excellent in system sizing and cost analysis, Matlab/Simulink is excellent in system simulation, but LabVIEW is excellent in monitoring and visualization. Also you can use LabVIEW in simulation and use Matlab in GUI (Graphical User Interface).
