增量配电网差异化配电价格模型研究与应用
|
摘要
为保证配电网企业的成本回收和合理收益,同时实现不同负荷特性的用户差异化电价,提出了一种增量配电网配电价格制定模型。将配电价格分为基本配电价格和附加配电价格两部分,基本配电价格按照"准许成本加合理收益"原则,根据项目全寿命周期成本和基准收益进行核定;附加配电价格根据不同用户的负荷特性进行差异化制定。利用全寿命周期成本理论和综合权重计算方法对模型进行求解。以某增量配电网项目作为算例进行配电价格核定,并对不同网架方案下的配电价格核定结果进行比较分析。算例结果验证了该模型的有效性。
In order to ensure the cost recovery and reasonable profit of distribution network enterprises and enable differential distribution pricing for users with different load characteristics, a distribution price model for incremental distribution network is established in this paper firstly. The model divides the distribution price into two parts: the basic distribution price and the additional distribution price. Based on the principle of "permitted cost and reasonable profit", the basic distribution price is made according to the life cycle cost and the benchmark income of the project. The additional distribution price is made differently according to the load characteristics of different users. Then, the model is solved by the theory of life cycle cost and the calculation method of comprehensive weight. Finally, a project of incremental power distribution network is used as an example to make the distribution price. Then this paper compares and analyzes the different distribution prices in different grid schemes. The results of the example verify the effectivity of this model.
