摘要(Abstract)：

可再生能源是全球能源转型和低碳发展的重要解决方案,含高比例可再生能源是未来电力系统发展的必然趋势,而高比例可再生能源电力系统的核心骨干网架直接关系到系统在灾害条件下的生存性、可靠性和可再生能源的消纳率。分析了高比例可再生能源电力系统的核心骨干网架的特征。随后结合电力网络中不同类型节点的特点,基于拓扑特性和电气参数分别构建各类节点的重要度评价指标体系,并采用熵权-理想解法评价各类节点的相对重要度。根据节点的相对重要度,构建了两阶段核心骨干网架优化模型:第一阶段模型针对重要负荷节点进行网架优化;第二阶段模型针对电源节点进行优化,最终得到包含风电场、光伏电站和常规机组的核心骨干网架。修改后的含高比例可再生能源的IEEE-118节点系统的仿真结果表明,文中策略能够较全面地评估高比例可再生能源电力系统的各类节点的相对重要度,优化得到的核心骨干网架能够保障对重要负荷的供电,且具有较高的可再生能源渗透率与利用率。
