摘要(Abstract):
如何对实施需求响应(demand response,DR)的成本效益进行有效评判是智能配电网(smart distribution network,SDN)规划中必须考虑的重要问题。为此,提出了一种综合评价模型。首先,通过分析当前电力市场环境下SDN参与主体及其利益需求,构建了涵盖技术、经济、环境等多方面在内的DR效益综合评价指标体系。该体系通过引入区间型数据指标,能够有效计及各类不确定因素对DR效益的影响作用。在此基础上,根据问题特点,进一步提出了一种可适应上述不确定性条件下决策的区间灰色关联理想点分析方法。该方法采用专家打分和区间中心点距离法相结合的混合赋权策略,以实现对决策者主观意愿及评价指标自身信息价值的合理兼顾;此外,为避免分析过程中分辨系数选择不当对评价结果造成的不良影响,还提出了一种针对分辨系数的动态调整策略,以提高模型在实际应用中的鲁棒性及判别能力。算例结果验证了所提方法的有效性。
