摘要(Abstract)：

针对孤岛依赖传统化石能源供能引起的污染及碳排放高的问题，提出了一种考虑碳排放的孤岛综合能源系统多目标规划优化方法。在构建设备模型的基础上，考虑气候参数波动对可再生能源出力的影响，逐时模拟系统全年运行情况，以系统的生命周期成本及生命周期二氧化碳排放为优化目标，结合非支配排序遗传算法Ⅱ构建了孤岛综合能源系统多目标规划优化模型，采用加权平均算子对优化结果决策；以烟台某孤岛为例，分析了以典型日和全年逐时数据作为模型输入对规划结果的影响，探究了可再生能源设备投资变化和天然气价格以及风光装机和蓄电池容量对优化目标的影响，获得了不同目标权重下各设备的最优容量。结果表明，配置可再生能源及蓄电池可使生命周期二氧化碳排放降低26.95%～55.96%，但当生命周期二氧化碳排放权重由0.6增至1.0时，主要依赖增加蓄电池装机容量降低碳排放，生命周期成本增加210.13%，而生命周期二氧化碳排放仅降低8.59%。该孤岛综合能源系统规划方法为决策者在孤岛规划综合能源系统时权衡低碳成本和能源供应经济性提供了参考。
