ZENON, Eric  and  ROSELLON, Juan. Optimación de las redes de trasmisión eléctrica en Norteamérica, teoría y aplicaciones. El trimestre econ [online]. 2012, vol.79, n.315, pp.575-600. ISSN 2448-718X.

We present a hybrid mechanism application for the electrical system network expansion in Mexico, United States and Canada. The application is based on redefining the transmission output in terms of "point-to-point" transactions or financial transmission rights (FTR); rebalancing the fixed and variable parts of a two-part tariff; as well as in the use of nodal pricing. The expansion of the transmission is carried out through the sale of FTR for the congested electrical lines. The mechanism was tested in the national electric system of Mexico (SEN) with 25 nodes and 34 power line, in the Pennsylvania-New Jersey-Maryland (PJM) grid with 17 nodes and 31 lines, and finally in the Ontario network (Independent Electricity System Operator, IESO) with 10 nodes and 10 lines. The results thereof indicate that prices converge to the marginal generation cost, congestion decreases and the social benefit increases in the three systems, regardless of the organization of the electrical system, the network topology or the type of installed generation capacity.
