区域级综合能源系统多能耦合优化研究

Multi-energy Complementary Optimization Research on Local Area Integrated Energy System

综合能源系统是未来能源消费方式的重要发展方向,按照不同能源品味的高低进行综合互补利用,以取得最合理的能源利用效果和经济环保效益显得至关重要。从功能模块、子系统、区域级综合能源系统三个层级进行模型构建,在合理配置多种功能模块的基础上进行各子系统和综合能源系统的能量平衡计算,建立能耗目标、经济目标、环保目标三种单一目标以及由此任意组合得到的多目标评价指标,制定多能耦合优化策略,实现综合能源系统设计中的方案配置优化。

The integrated energy system（IES） is an important developing direction for future energy use. The tradeoff between energy system setting and economic and environmental benefit is a paramount design consideration for multi-energy complementary system.In this paper,a general model was established based on three levels consisting of function unit,subsystem,and local area IES.Then,the energy balance calculation of subsystem and IES was performed after rational allocation of function unit. Furthermore,the model provided the optimal IES setting scheme satisfying energy consumption,economic,or environment protection single evaluating indicator or the multi-complementary evaluating indicator requirements.
