摘要

为平衡微电网的㶲效率和经济成本以及保证优化配置结果的准确性与客观性,提出考虑㶲效率的含氢储能冷热电联供型独立微电网多目标容量优化配置方法。首先,考虑电-氢-电转换时的余热回收,搭建包含风力发电系统、光伏发电系统、氢储能系统、空气源热泵与吸收式制冷机的独立微电网系统。其次,引入㶲分析法用以衡量系统内多能源的耦合关系及能源利用水平,以系统经济成本和㶲效率为优化目标建立多目标容量优化配置模型。最后,采用结合客观权重赋权法-优劣解距法（CRITIC-TOPSIS）的ε-约束法进行求解,得到兼顾系统经济成本与㶲效率的最优配置结果。算例验证了所提模型与方法的有效性,在不同典型日场景下均可满足多负荷的需求。

Abstract

To balance exergy efficiency and economic cost of microgrids, and to ensure the accuracy and objectivity of the optimization results, a multi-objective capacity optimization method is proposed for hydrogen-based combined cooling, heating, and power （CCHP）independent microgrids, with a focus on exergy efficiency. First, the recovery of waste heat during the electricity-hydrogen-electricity conversion process is considered. An independent microgrid system is proposed, which includes wind and photovoltaic power systems, hydrogen storage systems, air source heat pumps, and absorption chillers. Secondly, the coupling relationship and energy utilization levels of various energy sources in the system are measured using exergy analysis. A multi-objective capacity optimization model is then created with the optimization goals of system's economic cost and exergy efficiency. Lastly, to acquire the best configuration results that consider system's economic cost and exergy efficiency, the ε-constraint approach in conjunction with CRITIC-TOPSIS is employed. The illustration verifies the validity of the proposed model and method, which can satisfy the demand of multiple loads in different typical day scenarios.
