Abstract

The ERCOT Test System developed in this study is an open-source platform permitting dynamic performance evaluation of existing and proposed new market features for the ERCOT energy region. The test system models ISO-managed day-ahead and real-time wholesale power markets operating over a high-voltage transmission grid during successive days. Market operations capture salient features of actual ERCOT market practices. Clustering and triangulation methods permit users to construct synthetic transmission grids with buses and lines configured in accordance with ERCOT generation, load, and grid data. A complete 8-bus ERCOT test case is developed and implemented to illustrate the capabilities of the test system. Ongoing studies making use of the test system to implement the transmission component for integrated n and distribution system studies are also reported.
