摘要(Abstract)：

可再生能源大规模并网使电力系统基本形态和运行特性发生巨大改变,在规划初始阶段评估电力系统对可再生能源强波动性及不确定性的适应能力,对保障电力系统可靠运行、提升可再生能源消纳水平具有重要意义。针对适应性含义广泛且难以量化评估的问题,首先,从高比例可再生能源系统特征及实际运行状态出发,提出计及电网运行安全性、效率性、稳定性和供需平衡充裕性的电网结构及电源容量适应性指标,综合评价电网、电源发展对可再生能源的接纳能力。然后,基于适应性指标,建立考虑网-源协同优化的输电网多目标规划模型。针对各目标量纲不统一的问题,采用非线性化改进主成分分析法对每代种群个体进行综合决策以获取最优方案。最后,以Gaver-18节点测试系统进行算例仿真,其结果表明所提出的指标及规划模型能够在网-源协同的基础上,有效改善系统源荷平衡,提升系统高效、安全、稳定运行的能力。
