Has anyone tried to use python to perform MUST analysis and retrieve the results ? I was able to run the analysis using the record function, but haven't been able to retrieve the results in python yet. Below is the syntax that was used to perform the analysis.

ierr=mustpy.multdcfcitc(...)

Model your load, conduct a powerflow assessment. You can keep increasing your load until you hit a constraint in your system like low/high bus voltage, line or transformer overload, etc.

You can improve speed by utilizing parallel processing which will use multiple cores of your machine. Just to get a sense of speed improvement, you can initially split your job into multiple small batches(e.g. 4 batches of 25 simulations each) and trigger all of them at once. If this helps, you can then create python scripts to automatically do this for you.

I don't believe it is possible. Results of the ACCC function is stored on .acc file. You will have to use pssarrays module to retrieve the results from .acc file.

Hi ffl, would you mind providing a link to the document you are referring to?

It is possible using python in PSSE, but will require some effort. You would have to read your load and generation pattern for each hour, update the case with these values, solve, and then read the parameters of your interest. You could then write these parameters into a csv/text file for further analysis.

I am trying to use RELIND_2 API to perform some reliability assessments. Apparently, all results are displayed in terms of text report. I was wondering if there was a way to get those results into a python list for post processing rather than trying to read through the text reports.

Thank you all for your responses. This is adequate information for me to get started.

Is there an easy way via python scripting to use multiple cores on a single computer for PSSE Dynamics Run. It is taking too long to complete dynamics runs, and I suspect the default system is only using a single core. Any help will be appreciated.

I wrote a similar python script to export all branch and voltage violations in an excel sheet. You can extract the list of contingencies from .acc file using acccsummary function. You can then loop through each contingency using acccsolution to get the branch and voltage violation flows. You are right, this will give all the flows in all the monitored branches and volts in monitored buses, but you can do some filtering later to just keep the violations. Finally, you can dump the results in an excel sheet using xlwt or a csv writer function. Its a little complicated, but trust me all your dreams will come true at the end.
