摘要:
      区域综合能源系统(RIES)由于广泛涉及电/气/热/冷等多种能量形式耦合,其规划工作面临诸多挑战。提高能量利用效率是RIES规划的重要任务之一,传统能量效率的定义仅计及了能量在数量上的变化,却忽视了能量在品质上的差异,无法准确地衡量RIES的能量利用水平。文中提出使用兼顾数量和品质的效率作为衡量RIES能量利用水平的标准。首先,定义了能量品质系数的概念用以量化不同形式能量的品质差异,并提出基于黑箱模型的RIES总体效率计算方法。然后,建立了五层级能源集线器模型用以处理多能耦合问题,确保区域能量供需平衡。接着,以经济性和效率为优化目标构建了RIES多目标规划模型,设计了兼顾规划与运行的双层优化结构,并联合运用改进的非支配排序遗传算法(NSGA-Ⅱ)和内点法实现模型高效求解。最后,选取广州市某工业园区RIES作为算例对所提方法进行验证。
Abstract:
      The planning of a regional integrated energy system(RIES)faces many challenges because of its extensive involvement of multiple energy forms coupling, such as electricity/gas/heating/cooling. Improving the efficiency of energy utilization is an important task for RIES planning. The traditional energy efficiency only takes into account the change of energy in quantity, but ignores that in quality, which is impossible to accurately measure the energy utilization level of a RIES. In this paper, exergy efficiency considering both the quantity and the quality of energy is proposed as the standard for measuring the energy utilization level of RIES. Firstly, the concept of energy quality coefficient(EQC)is defined to quantify the differences among different energy forms, and the exergy efficiency calculation method of RIES is proposed. Secondly, a five-level energy hub model is established to deal with multi-energy coupling problems and ensure regional energy supply and demand balance. Thirdly, the multi-objective planning model with objectives of economy and exergy efficiency is proposed, and a bi-level optimization structure is designed considering both planning and operation, and the improved non-dominated sorting genetic algorithm-Ⅱ(NSGA-Ⅱ)and interior-point method are jointly used to realize the high-efficient solving of the model. A certain RIES in Guangzhou is selected as the case study to verify the proposed method.
