| 为了从经济运行角度研究分布式电源配电网线损分摊，给出一种基于经济运行分析的分布式电源配电网线损分摊计算方法。首先，采用等效电阻法计算最小配电网线损，并据此计算接入分布式电源前后配电网的经济运行负载区间；其次，分析配电网接入分布式电源前后经济运行负载区间变化的原因，并据此构建不同的运行场景；最后，采用潮流追踪算法计算分布式电源线损分摊电量，设置对应的奖惩系数修正计算的线损分摊电量。实例分析结果验证了所给方法的有效性和合理性。 |

| In order to research the problem of line loss allocation in distribution network with distributed generators from the perspective of economic operation, a calculation method of line loss allocation based on economic operation analysis for distribution network with distributed generators is proposed. Firstly, the minimum line loss of distribution network is calculated by using equivalent resistance method, then the economic operation load interval of the distribution network before and after the distributed generator is connected is calculated. Secondly, the reasons of the economic operation load interval change before and after the distribution network is connected to the distributed generator are analyzed, and different operation scenarios are constructed accordingly. Finally, the line loss allocation of distributed generators is calculated by using the power flow tracing algorithm, and the calculated line loss allocation is corrected by setting the corresponding reward and punishment coefficients. The results of example analysis verify the validity and rationality of the proposed method. |
