| 中文摘要: |
| 随着多能互补政策的持续推进,大量不同形式、能源品质各异的能源并入冷热电联供（combined cooling heating and power,CCHP）型微电网,其在微电网中做有用功的能力各不相同。同时,由于当前基于热力学第一定律制定的多能耦合微电网调度策略,难以区分不同形式能源的品质差异,缺乏完备的能源品质指标量化体系,导致各类能源做有用功的能力难以充分发挥。为此,引入基于?理论的热力学第二定律能量分析方法,构建了考虑新能源并入的多能耦合微电网调度模型,建立了适用于多能耦合微电网的能源品质指标量化体系,制定了一种基于?理论的多能耦合微电网调度策略,解决了现有调度策略难以充分发挥各类能源做有用功能力的问题。最后,为了实现容量配置与优化调度的协同优化,避免各自独立研究与优化的局限性,基于理论构建了多能耦合微电网配置与调度的双层优化模型。 |
| 英文摘要: |
| 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. |
