How does a microgrid market work?
The market operation proceeds in three stages: negotiation, clearing, and settlement. At the beginning of the negotiation stage, the microgrid units register with the market operator, indicating that they wish to participate in the market [ 89 ]. The market operator then updates the forecasts and broadcasts initial prices.
