These data are based on the ones available online and their use was authotized by Prof. Rich Christie: 'Data in http://www.ee.washington.edu/research/pstca/ is public domain and unrestricted from further distribution.'

The file refers to a 118 bus system, and a variant with an increased demand that simulates the system growth. This system was used to do simulations of transmission tariff allocation methods, being in the file the results of two methodologies applied to the system (Nodal method e Bilevel Transmission Tariff Allocation). The system data is based on the IEEE 118 bus system (http://www.ee.washington.edu/research/pstca/pf118/pg_tca118bus.htm) with the addition of the missing information about maximum and minimum generation, transmission capacity, and lines’ total cost. Additionally, test systems with 6, 12, 18, 24 and 30 buses are given. They can be used to evaluate computational running times.
