Hi all,

I have some issue to plot out file with matplotlib. Here is the code i've used.

outfile=tk.askopenfilename(title="Select a .out file",filetypes=(("PSS/E outfile","*.out"),("all files","*.*")))

### Run dyntools to extract the data###
chnfobj = dyntools.CHNF(outfile)

short_title, chanid_dict, chandata_dict = chnfobj.get_data()


### Extract time as a variable###
time = chandata_dict ['time']

f = chandata_dict['freq']

Here is the error

Traceback (most recent call last):
  File "C:\Users\dyntoolstest.py", line 34, in <module>
    f = chandata_dict['freq']
KeyError: 'freq'

What should i put in [] of f ?

Thank you in advance.

thanks for your answer, btw, in load flow, how about the pgen and pmax?

currently i am working on effect of renewable energy on system frequency and how battery energy storage can solve this issue. unfortunately i have no idea on how to model BESS in PSSE32. can someone guide me on how to model bess in load flow as well as on dynamic modelling.
