摘要
针对居民阶梯电价分段电量边界的确定存在一定的人为因素和随意性的不足,提出了基于密度聚类的居民阶梯分段电量综合制定方法。首先,应用密度聚类分析技术,根据户月均用电量邻域内的户数密度,按户月均用电量对居民用户进行初步分类。然后,应用家庭电器设备估算法和概率统计方法确定各档分段电量及其覆盖率的范围,以此为约束合并聚类分析的初步分类,构造各档分段电量的可选择方案,并建立了各档分段电量的最优决策模型,从多方案中选择出综合最优的分段电量水平。实例验证了该方法的正确性和合理性。
There are a certain anthropogenic factors and arbitrariness during the determination of residential step-shaped electricity consumption levels in residential area, which is the base for drafting step-shaped electricity rate in residential areas. For this reason, a synthetical method to draft step-shaped electricity consumption levels in residential area, which is based on variable-density clustering, is proposed. Firstly, the residential consumers is preliminarily classified by variable-density cluster analysis based on monthly average electricity consumption of each family, which is decided according to the density of family numbers in the neighborhood of monthly average electricity consumption of the families; then the estimation of household appliances and probabilistic method are utilized to decide the step-shaped electricity consumption in each step and corresponding rate of coverage, and taking them as constraints the preliminary classifications by cluster analysis are merged to construct selectable scheme for each step-shaped electricity consumption; finally, optimal decision-making models for step-shaped electricity consumption in all steps are built, and the synthesis optimum electricity consumption level in each step is chosen from these schemes. The correctness and reasonableness of the proposed method are verified by practical cases.
