# Optimal Power Flow Test Cases (2021)

This repository provides a series of OPF test cases that were used in the following paper. These test cases are made available here to allow other authors to compare their solutions to ours.

V. Roberge and M. Tarbouchi, “Hybrid Method Based on Metaheuristics and Interior Point for Optimal Power Flow,” Submitted to Fifth International Conference on Intelligent Computing in Data Sciences (ICDS 2021), Fez, Morocco, 2021.

Notes:
1. The naming of the different test cases is based on the number of buses.
2. The file format is compatible with the MATPOWER Case Format v2 but includes additional structures for transformers and SVARs.
3. The solutions with the lowest cost are highlighted in bold.
4. To test a solution, run a power flow analysis in MATPOWER and compute the generation cost as follows:

mpc = runpf(‘case30_ga’);
cost = sum(totcost(mpc.gencost, mpc.gen(:,2)));
