Hierarchical Interactive Mechanism for Flexible Demand Response of Multi-Energy Microgrids

With the development of microgrid technology and demand-side aggregating technologies, a flexible and cost-effective interactive mechanism has become an effective solution for optimizing energy utilization in microgrids and promoting flexible interactions among multiple adjustable resources. This study focuses on multi-energy microgrids as the research object. Firstly, to promote flexible interactions among multiple adjustable resources, a multi-level interactive architecture for multi-energy microgrid systems is established. Secondly, various interactive modes such as demand-side multi-energy coordinated operation and joint demand response are discussed. Based on this, considering the complementary demand between thermal energy and electrical energy within the microgrid, a hierarchical demand response model for microgrids is established. Furthermore, a hierarchical interactive mechanism for responding to the demands of multi-energy microgrids is designed, which effectively reduces the operational costs of microgrids and achieves a win-win situation for multiple parties. Finally, the effectiveness and economic feasibility of the designed mechanism are verified through simulations.
