Modeling and simulation of PJM and northeastern RTOs for interregional planning

PJM operates the largest transmission and market system in the U.S. It also borders with other regional transmission organizations, such as Midwest ISO, and New York ISO (NYISO). The issue of transmission planning is not just confined to each RTO internal region, but also crosses borders with neighboring entities. Due to a recent push by federal regulatory authority via Order 1000, it becomes necessary to consider transmission planning (upgrades or new transmission facilities) that touches more than one regional entity. In light of that, it is important to develop model, database and simulation capabilities which can be used to represent and simulate for more than one RTO. One such exercise for PJM is to model three RTOs - PJM, NYISO, and ISO New England (ISO-NE), in a combined and consistent fashion so that we can evaluate the economic merits of any proposed cross-border transmission projects or increase of tie capacities. In this paper, we will show such a model, including preliminary simulation results of base case and other sensitivity cases.
