MATPOWER

ANDES supports MATPOWER data in version 2 in part for power flow calculation. The following fields are supported:

• mpc.busMVA

• mpc.bus

• mpc.gen

• mpc.branch

• mpc.area

• mpc.bus_name

Other fields are not supported, most notably, mpc.gencost.

Power flow calculation results for MATPOWER cases are typically identical to that from MATPOWER using default settings. These settings include no reactive power limits and following all generator connectivity status. Discrepencies in the power flow solution between ANDES and MATPOWER are typically due to configuration issues or different interpretation of the data, rather than in the power flow models.
