计及多种扰动源的有源配电网电能质量区间量化综合评估
摘要：受到分布式电源随机性和用电负荷波动性的影响，有源配电网不确定性增加。基于具体实测数据点值的传统配电网电能质量评估方法未考虑到多种扰动源引起的大量不确定因素。因此提出了一种考虑配电网不确定性，适用于处理区间电能质量指标的区间量化综合评估方法。首先给出了区间指标数据的归一化处理方法，其次提出了一种多专家咨询G1法与改进熵权法相结合的组合赋权方法，再次针对区间数据的特点，采用基于可能度计算的排序方法对评估结果进行排序，使结果清晰直观。最后以IEEE 33节点配电系统为算例，验证了该方法的有效性和可行性。
Abstract:Due to the affection of both randomness of distributed generations and fluctuation of electricity loads the uncertainty of the active distribution network increases. In traditional power quality assessment method for distribution network, which is based on the measured value of data points, a lot of uncertain factors caused by multiple disturbance sources have not been considered. Thus, an interval quantization comprehensive assessment method, which took the uncertainty of distribution network into account and suited to deal with interval power quality indicators, was proposed. Firstly, a normalization method to process interval index data was given. Secondly, a combination weighting approach, in which the multi-expert consultation G1 was combined with the improved entropy weight method, was proposed. Thirdly, in allusion to the characteristics of interval data, an ranking method based on possibility calculation was used to rank the assessment results to make the results clear and intuitive. Finally, utilizing IEEE 33-bus distribution system for calculating example, the effectiveness and feasibility of the proposed method were verified.
