Abstract

To address the intermittency of distributed energy resources and the coordinated operation of microgrid clusters, this paper investigates interaction strategies for microgrid clusters considering a hierarchical control framework. First, a refined microgrid operation model is developed, incorporating flexible load constraint mechanisms. Based on a price elasticity matrix, the model quantifies users’ multi-period response characteristics to electricity prices, forming an optimized microgrid dispatch model that accounts for demand-side response. Second, considering the hierarchical control framework, an interactive coupling model for microgrid clusters is proposed, and an optimal scheduling model is developed to enable mutual assistance among multiple microgrids. Finally, compared with traditional methods, the proposed strategy improves renewable energy consumption, reduces operating costs, and enhances the flexibility of power interaction.
