摘要
The paper proposes a novel optimization framework for smart microgrids for both scheduled and unscheduled multiple transitions between grid-connected and isolated modes. The optimization aims at maximizing the overall microgrid profit, from selling energy to grid, and minimizing consumption costs by scheduling dispatchable loads and generation, energy storages, and load curtailment while satisfying all network and operational constraints. For unscheduled transitions, the time of mode transitions in the planning period is not known in advance. So, the optimization is reinitialized and restarted online after considering the most updated state. Network constraints for three-phase unbalanced distribution microgrid model are adopted in details in convex formulation. Bidirectional energy trading with the grid is considered. Moreover, Model Predictive Control (MPC) is used for handling uncertainty in renewable generation and load. Comprehensive simulation results are given for validating the proposed algorithm and comparison is made between results of scheduled and unscheduled optimization. (C) 2016 Elsevier B.V.
