摘要

本文提出了一种新算法,用于分配以分布式发电为特征的径向配电网络(DN)中的每日能量损失。该算法采用面向分支的方法,该方法被公认为解决径向配电网问题的最有效方法。为了在 DN 环境中实施该方法,采用了电流求和算法。统计方法用于整理每日负荷和发电曲线的完整数据,提供确定能源损耗分配所需的关键数量。利用统计特性,建议的方法可计算出从每日负荷和发电曲线中收集的数据的单个等效值。然后利用这些值进行功率流计算,并分配能量损失。为验证所提方法的有效性,在 30%、100% 和 150% 的负荷水平下,对 33 节点和 69 节点径向 DNs 进行了测试。测试结果与损失分配的能量求和法和损失分配的重复几何方案进行了比较。在所有三种负荷水平下,所提出的方法都表现出了无偏性,避免了将损失的经济负担分摊到各组用户和发电机上。此外,拟议方法的性能非常适合,可接受性很高。这凸显了所提方法的可靠性,在 10%的可接受误差范围内取得了结果。

Analytical approach for allocation of energy losses in active distribution system using the method of energy summation

Analytical approach for allocation of energy losses in active distribution system using the method of energy summation

This paper presents a new algorithm designed for the allocation of daily energy losses in radial distribution networks (DNs) featuring distributed generations. The algorithm employs a branch-oriented approach, widely acknowledged as the most effective method for addressing issues in radial DNs. To implement this methodology in a DN environment, a current summation algorithm is utilized. The statistical approach is employed to organize the complete data of daily load and generation curves, providing key quantities necessary for determining energy loss allocation. By leveraging the statistical characteristics, the proposed method calculates the single equivalent values of the collected data from the daily load and generation curves. These values are then used to perform power flow calculations and subsequently allocate the energy losses. To validate the effectiveness of the proposed method, tests are conducted on 33-node and 69-node radial DNs under load levels of 30%, 100%, and 150%. The obtained results were compared with those from the energy summation method of loss allocation and the repetitive geometric scheme of loss allocation method. Under all three load levels, the proposed method demonstrated an unbiased approach, avoiding the addition of economic burden of losses over groups of consumers and generators individually. Moreover, the performance of the proposed method was found to be well-suited and highly acceptable. This underscores the reliability of the proposed approach, achieving results within an acceptable error margin of 10%.
