I am interested to simulate distribution networks with distributed generation utilizing custom controls. Simulink is quite versatile in control system design and is friendly for people preferring visual approach to programming. But I am not always satisfied with how it solves power flow for detailed network models.
Lets say that I am looking for more reliable power flow solvers, but with control system design versatility of Simulink (preferably with visual programming). Any suggestions?
Dear Ognjen,
I recommend you try the open source software/tools 'PSAT' (Power System Analysis Toolbox) which is available at the following link.

Hello Morteza,
Thanks for suggestion. I used PSAT before, but only briefly with a different purpose. Now looking at it again, it seems it only uses one-line diagram in network modeling? I would need to model explicit three-phase system. Sorry for not mentioning that earlier.
While PSAT does not show the results and the dynamics on the single line diagram, Matlab/Simulink with the voltage, current, and power meters connected is somehow better. Power-world Simulator, and DigSilent Power Factory also depict the results and dynamics on the single line diagram. Hope at least one of these meets your goals.
Hi,
You could try NEPLAN. I think it supports the option you are looking for but you shall need to do some settings in the Setting Option Menu.
Dear Ognjen,
As I am really interested in using computer programming languages by my own efforts instead of using commercial softwares, another choice would be MATPOWER which is free and available at the following link. Moreover, it provides more control parameters for making your problem flexible.

Please take a look at www.ee.iitb.ac.in/~peps/downloads.html
and transient stability programmes
Try OpenDSS. It is an open source software for Distribution system. It handles power flow problem very fast with easiness and wide options for control
Hi,
recently simulation software oriented to analysis of distribution systems with DG-s are developed, as OpedDSS (also Monsef recommended above) and Gridlab-D: http://sourceforge.net/projects/electricdss/ ; http://www.gridlabd.org/. Both of them can solve unbalanced distribution network and both are costless. OpenDSS does not have GUI interface, for GridLab-D I do not know (not use it yet).

I think PowerWorld is quite good one as far as animation is considered and it is also user friendly.
