3. Commands

Note:
More information above main commands of API PyPower are updated with the latest trends, best practices, and main methods on:

usage

from https://pypi.org/project/PYPOWER/

to list the commands options

pf h

PYPOWER includes a selection of test cases. For example, to run a power flow on the IEEE 14 bus test case:

pf -c case14

The opf command has the same calling syntax. For example, to solve an OPF for the IEEE Reliability Test System and write the solved case to file:

opf -c case24_ieee_rts --solvedcase=rtsout.py

Command DC power flow

import os
import sys
print(os.getcwd())
#cls
from pypower.api import case9, ppoption, rundcpf
ppc = case9()
ppopt = ppoption(PF_DC=True)
print("load case and execute dcpf")
ppc = case9()
r = rundcpf(ppc, ppopt)
