配电网中容量电费定价方法

PRICE SETTING OF CAPACITY CHARGE IN DISTRIBUTION SYSTEM

在传统的配电网容量电费的电价中 ,只考虑了用户的容量大小 ,而没有考虑用户的功率因素、用户对供电的可靠性要求以及用户的具体位置等用户属性。通过对配电网用户属性的分析 ,提出了一种用模糊聚类的方法对配电网内不同性质的用户进行分类的方法 ,并依照此分类将配电网中的容量费用按一定的权重在不同类别的用户间进行分配。此全新的容量电费电价方法 ,较全面地考虑了用户容量大小、用户的具体位置、用户的功率因数、用户对供电的可靠性要求等因素 ,避免了将配电网内的投资费用仅按容量进行分摊的局限性 ,使配电网内的投资费用的分摊趋于合理。实例研究表明 。

A novel method for the setting of capacity charge within a distribution system is proposed in this paper. This new method apportions the capacity charge based on a fuzzy clustering categorization of consumers. Consumers in the system are first categorized to different classes according to their properties by using fuzzy cluster principle. Then, the charge of the system capacity is rated among these various classes with weighted factor. In contrast to the conventional setting method which only takes into account the capacity of consumers, while ignoring other properties such as power factor. Reliability, and location of the consumers, the presented method considers them all together, which eliminates the limitation of capacity-based only apportionment within the system, making the apportionment of the investment more reasonable. Experiments show that this setting method responses to the consumers' properties more properly.
