Multi-Element Collaborative Optimization Strategy for Microgrids Considering Flexibility Resource Index Constraints

With the advancement of energy technology, microgrids, as a form of power grid that can fully utilize wind and solar resources, have higher demands for their flexibility. Therefore, a multi-element collaborative optimization strategy considering flexibility resource index constraints for microgrids is proposed. First, considering the output characteristics of various flexibility resources and the uncertainty of wind and solar power, a quantification model for flexibility resource demand and supply is established. Secondly, a multi-element collaborative scheduling model is developed, aiming to minimize the total operation cost and flexibility deficit of the microgrid. Finally, the effectiveness and feasibility of the proposed method are demonstrated through case studies.
