Hi, Dear Dr. eidiani

I think  DIgSILENT is the best software for a power system simulation.

Dear Mostafa, I dont know the systems you mention, but you cannot go wrong with SimPowerSystems for Matlab Simulink. It can also do simulations for solar power and wind power renewable energy systems. 

We also use simulink for simulation of thermodynamic concentrated solar thermal heat systems for off-grid isolated power systems. What is helpful is that and the platform Simulink allows one to integrate the simulation of both thermodynamic, thermomechanic and electrical power simulation all in the same model (we even include microgrid and smartgrid in the same model).

If you are with a university, you can get an academic license.

Hi, Dear Dr. eidiani

I think  DIgSILENT is the best software for a power system simulation.

Generally, the suitable software for simulating the power systems is MATLAB, but sometimes it is very difficult to use it. According to software mentioned in your question, the DIgSILENT is the best one due to a faster response even in a large power system. However, I suggest to add a nice software for  small power system simulation called PSCAD and PSIM for power electronics applications in power system and electrical machines.

hi i think that best softwares matlab and Digsilent for power system

Hi Thank you for your reply I use the DIgSILENT Power Factory software.

I find a useful link

Hi, Dear Dr. eidiani

I also agree with your opinion

Nowadays, the DIgSILENT is widely used for dynamic response simulation of power system. Onward, Always.

You may just search Google for "power system real time simulator". You will find the best regarding software.

Dear Prof. Shahram Montaser Kouhsari

Please see this question:

Why people answer my question with a search from google?

https://www.researchgate.net/post/Why_people_answer_my_question_with_a_search_from_google

I use DigSilent, ETAP, Neplan and Power World. All of them are usually taking into account the problem that must be solved. Try NEPLAN or ETAP and see the differences!

I recommended to search Google since the best software has been omitted from the list, that surely are PASHA and POUYA software

DIgSLENT and ETAP are two exceptional software for power system analysis. It is noted that, DIgSILENT is appropriate for huge systems like modelling Iran Electrical Network. In contrast, ETAP is appropriate for modelling industrial network, for example electrical network of a factory.

DIgSILENT has distance protection, and does not have Differential (of course, it can be build through its DSL). In contrast, ETAP has differential Protection and does not have Distance protection.

All in All, ETAP is easy to work and some of its features like cable sizing or transformer sizing is very interesting. DIgSILENT is not easy to work but it is the best choice to analyse big systems.

I've heard lots of good things about PASHA during my project in Isfahan Steel Company, but I do not work with it.
