摘要(Abstract)：

分布式可再生能源的广泛接入对配电网的规划与运行产生重大影响,如何准确评估配电网的最大并网能力是一个配电网规划中的重要问题。该问题的最大挑战是在评估模型中如何刻画分布式电源出力的不确定性,并进行有效求解。为此,提出了一种基于机会约束的配电网分布式电源容量评估方法。该方法考虑了分布式电源出力及负荷预测的不确定性,将约束构建为线性机会约束形式。通过假设预测误差服从各个变量的边际分布相互独立、均值为0的概率分布,进一步将该机会约束模型转化为可被有效求解的混合二阶锥规划模型。最后,基于IEEE 33节点配电网络的算例给出了所提出方法的评估结果。基于文中提出的分布式电源容量评估方法在给定约束越限概率下可得到较大容量的接入方案。
