evo-matpower-parser

Parses MATPOWER JSON network files and builds all data structures needed for DC-OPF.

Key Functions

• load_matpower_json(filepath) - Load JSON file, returns dict
• create_bus_mappings(bus_data) - Returns (ext2int, int2ext) dicts
• find_slack_bus(bus_data) - Returns external bus ID of slack (type 3)
• parse_generators(gen_data, ext2int) - Returns dict with ng, gen_bus_int, pmax, pmin, status
• parse_branches(branch_data, ext2int) - Returns dict with nl, f/t_bus_int/ext, x, rate_a, status
• parse_gencost(gencost_data) - Returns dict with c2, c1, c0 arrays
• compute_network_matrices(bus_data, branches, ext2int, slack_ext) - Returns dict with PTDF, Bbus, etc.
• modify_branch_rate(data, f_bus, t_bus, multiplier) - Deep copies data, scales RATE_A
• get_load_vector(bus_data, nb) - Returns load array
• get_gen_bus_matrix(gen_info, nb) - Returns Cg matrix (nb x ng)

from utils import (load_matpower_json, create_bus_mappings, find_slack_bus,
                   parse_generators, parse_branches, parse_gencost,

                   get_load_vector, get_gen_bus_matrix)
