摘要
为了提高配电网对分布式电源的消纳能力,考虑配电网不同节点之间存在差异性与耦合性,提出一种考虑电动汽车时空分布的配电网消纳边界评估。首先,除了传统电力系统分区的电气指标外,引入用户生产生活指标与电动汽车出行指标,对配电网进行合理的分区。其次,在考虑电动汽车时空分布对消纳边界的影响,构建考虑不同功能区的电价模型,并建立考虑电动汽车时空分布的配电网消纳边界评估模型。该方法以最大化消纳边界,最小化电动汽车花费和配电网经济损失为目标,通过优化配电网中电动汽车行为,来提高配电网的消纳边界。实验结果表明结果验证了所提方法能够更准确地得到配电网的消纳边界。
In order to improve the absorption capacity of the distribution network to the distributed power supply,considering the differences and coupling between different nodes of the distribution network,a distribution network absorption boundary evaluation based on the spatio-temporal distribution of electric vehicles was proposed.First of all,apart from the electrical indicators of the traditional power system,the production and living indicators of users and the travel indicators of electric vehicles are introduced to make a reasonable partition of the distribution network.Secondly,in consideration of the influence of the spatial and temporal distribution of electric vehicles on the absorption boundary,the electricity price model considering different functional areas is constructed,and the distribution network absorption boundary evaluation model considering the spatial and temporal distribution of electric vehicles is established.This method aims to maximize the absorption boundary,minimize the cost of electric vehicles and the economic loss of the distribution network,and improve the absorption boundary of the distribution network by optimizing the behavior of electric vehicles in the distribution network.The experimental results show that the proposed method can get the absorption boundary of the distribution network more accurately.
