摘要

面向规模化屋顶光伏接入配电网急需进行有序控制的现状,提出了一种考虑源荷匹配特性的屋顶光伏并网的综合排序方法。首先,综合考虑负荷与光伏协调特性等需求,设计了兼顾光伏业主侧、电网侧和用电用户侧需求的综合评价指标体系;其次,提出了一种基于改进层次分析法(improved analytic hierarchy process,IAHP)-改进反熵权法(improved anti-entropy method,IAM)-博弈组合赋权法-改进逼近理想解法(improved technique for order preference by similarity to ideal solution,improved TOPSIS)的评价方法,先根据改进的层次分析法进行主观赋权,同时考虑到指标间的相关性和波动性,采用所提改进反熵权法确定各指标的客观权重,再基于博弈论思想获取综合权重,以确保权重的合理性,然后,为提高各方案的整体区分度,采用所提改进逼近理想解法对屋顶光伏接入方案进行排序。最后,以IEEE 33节点系统为例,在MATLAB平台验证了所提指标体系和排序方法的有效性。

Abstract

Aiming at the urgent need for orderly control of large-scale rooftop photovoltaic access to the distribution network, a comprehensive sorting method of rooftop photovoltaic grid-connected considering source-load matching characteristics is proposed. Firstly, considering the demand of load and photovoltaic coordination characteristics, a comprehensive evaluation index system is designed, which takes into account the demand of photovoltaic owner side, power grid side and power user side. Secondly, an evaluation method based on improved analytic hierarchy process-improved anti-entropy weight method-game combination weighting method- improved technique for order preference by similarity to ideal solution is proposed. Then, the subjective weighting is carried out according to the improved analytic hierarchy process, and the correlation and volatility between the indexes are taken into account. The proposed improved anti-entropy weight method is used to determine the objective weight of each index, and then the comprehensive weight is obtained based on the game theory to ensure the rationality of the weight. Moreover, in order to improve the overall discrimination of each scheme, the improved technique for order preference by similarity to ideal solution is used to sort the rooftop photovoltaic access scheme. Finally, taking the IEEE 33-node system as an example, the effectiveness of the proposed index system and ranking method is verified on the MATLAB platform.
