Abstract:With the advancement of multi-energy complementary policies, diverse energy sources with varying qualities are integrated into CCHP-type microgrids, but current dispatch strategies based on the first law of thermodynamics fail to distinguish energy quality differences and lack a quantitative index system, limiting the utilization of their useful work capacity. An exergy theory-based energy analysis method is introduced, a dispatch model considering new energy integration is constructed, an energy quality index system is established, and an exergy-driven dispatch strategy is proposed to address this issue. Finally, a two-layer optimization model for configuration and dispatch of multi-energy coupled microgrids is developed based on exergy theory to achieve collaborative optimization and overcome the limitations of independent optimization.
