Traditionally, electric system operators have dispatched generation to minimize total production costs, assuming a fixed transmission topology within the dispatch horizon. Implementation of smart-grid systems could allow operators to co-optimize transmission topology alongside generator dispatch; the technologies that would enable such co-optimization are still regulated as part of the monopoly...
