Coordinator

To ensure the energy supply equals demand at every moment across the transmission network, Independent System Operators (ISOs) clear the markets seeks to minimize the overall operation and production costs by coordinating the operation schedules of generation units in the network while considering operational and physical constraints of power systems. As mentioned above, the market is cleared by a two-settlement system: the day-ahead market and the real-time market. In the framework, the ISOs are modeled by the PCM Prescient. The DoubleLoopCoordinator will coordinate the operations among Bidder, Tracker, and Prescient for the simulations.
