I have a control code in C language. How can I write a wrapper for this c code, build the DLL, and attach it to the PSSE model? Any example please???

def CreateDLL(psseversion, keyname): # ____________________ # [vars]

mypathlib = False  # set PATH and LIB values using installed components
src_lst = []

work_dir = os.getcwd()
if len(sys.argv) > 1:
    keyname = sys.argv[1]
dllname = "%s_v33.11.0.dll" % (keyname)
dlllib = dllname.replace('.dll', '.lib')
try:
    os.remove(dlllib)
except:
    pass

for ext in ['*.flx', '*.f', '*.for', '*.f90']:  # include conec & conet files
    src_lst += find_files(ext, work_dir)  # get source files
objlibfiles = find_files('*.obj', work_dir)
objlibfiles += find_files('*.lib', work_dir)

ierr = psse_env_manager.create_dll(psseversion,
                                   src_lst,
                                   modsources=[],
                                   objlibfiles=objlibfiles,
                                   dllname=dllname,
                                   workdir=work_dir,
                                   showprg=True,
                                   useivfvrsn='15.0.285',
                                   shortname=keyname,
                                   description='User Model',
                                   majorversion=1,
                                   minorversion=0,
                                   buildversion=0,
                                   companyname='Enerzinx',
                                   mypathlib=mypathlib)

if name == 'main': psseversion = 33 keyname = 'Mydll' CreateDLL(psseversion, keyname)

this code works for building the dll for ver33 and 34. But if I use the same code for ver35, it throws the error message below.

fatal error LNK1112: module machine type 'x86' conflicts with target machine type 'x64'

Hi all,

I am writing a user-written model in PSSE. I need to measure a branch flow in PSSE. I passed From bus, To bus and Bus ID as ICONs. Inside my model, I used the bus ID as CHRICN. When I print it in DOCU, it is printed as 0. So, I need to convert this character to Integer. I used the read function. read(BID, *) BIDint. This function will convert character to integer. It is successfully compiled. But, when I run the model, the PSSE is crashing. Kindly help me with how to convert and print in the DOCU section.

I didn't get your answer exactly. Could you please give me a piece of code to do it.

Hi, the model is initialized from the load flow solution. I think we should solve the network solution first and read the Q value from the solution. This may solve the issue. But I don't have any idea to do it. In the case of the current injection model, normally we do this when IFLAG is true.

I have written a power plant controller model in PSSE. I need to initialize the PPC model with remote branch flow. I used the FLOW1() function to get the active and reactive power flow of the remote branch. Somehow there is a difference in the results between the steady-state model and this function output. The difference is very minor (0.02 MVAR). Due to this, I am getting initial suspects in the PSSE model, which is not accepted by many utilities.

CALL FLOW1(M+1,L+2,L+3,L+4) Q = VAR(L+3)

from load flow Q = 16.0042 MVAR, but from VAR(L+3) it is 15.99409 MVAR. Even though the difference is very small but it will show as a suspect.

Kindly help me to resolve this issue.

Thanks for your suggestion.

Hi Alex, Yes, now my code is working. Thanks for your support.

NSWICH command has been removed from common4.ins of v35. Is there any alternative function ? Please help me.
