In this dissertation, a feedback control concept is proposed for modeling a market-grid coupling. The contributions are fourfold: 1) Identification and characterization of an interoperable control between the power market and the power grid; 2) Design of a closed-loop MPC for the market-grid coupling; 3) Extension of the single control loop with a collaborative distributed MPC strategy for coupling distributed markets and grids; 4) Development of an adaptive load forecasting framework
