Multi-time Scale Coordinated Scheduling of Standalone Microgrid Considering Resource Flexibility

To cope with the large-scale access to renewable energy, more and more attention has been paid to the optimal scheduling of microgrid (MG). Considering the flexibility of various distributed generators, an optimized scheduling scheme with multi-time scales for multi-energy MG is proposed. The dayahead dispatching strategy provides a reference for the intraday scheduling, and can adjust the operation and on and off status of distributed resources to meet the operation requirements; intraday scheduling uses a rolling optimization method to guide the optimization and adjustment of the scheduling plan by formulating various distributed resource adjustment priorities. The results of the case analysis verify that the proposed model can effectively utilize the flexibility of distributed resources, ensure the safe operation of MG, and improve the economics of the system.
