【摘要】：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。
[Abstract]:How to evaluate the cost benefit of implementing demand response Dr is an important problem that must be considered in the planning of smart distribution network (smart distribution. Therefore, a comprehensive evaluation model is proposed. Firstly, by analyzing the main body of SDN and its benefit demand in the current power market environment, a comprehensive evaluation index system of Dr benefit is constructed, which includes technology, economy, environment and so on. By introducing interval data index, the system can take into account the effect of all kinds of uncertain factors on Dr benefit. On this basis, according to the characteristics of the problem, a method of interval grey correlation ideal point analysis is proposed, which can adapt to the decision under the uncertain conditions mentioned above. In this method, the expert scoring method and the interval center point distance method are combined to achieve a reasonable balance between the decision makers' subjective will and the evaluation index's own information value. In order to avoid the adverse effect of improper selection of resolution coefficient on the evaluation results, a dynamic adjustment strategy for the resolution coefficient is proposed to improve the robustness and discriminant ability of the model in practical application. The effectiveness of the proposed method is verified by an example.
