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。
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.
