摘要
分布式电源的规模化接入已成为我国区域配电网发展的必然趋势和核心特征。如何量化分析分布式电源接入对配电网损耗的影响,对于提升电力企业的经济效益具有重要意义。本文首先构建了计及分布式电源接入的区域配电网理论线损计算修正模型,进一步分析了分布式电源不同接入容量和不同接入位置对区域配电网合理线损标杆计算的影响,最后基于特定的供电电压序列(110/35/10/0.4)和Matlab仿真平台,仿真计算得出了计及分布式电源接入的区域配电网合理线损在不同电压等级的分布情况。本文的合理线损理论分析为电力企业的线损管理提供了借鉴和参考。
The large-scale integration of distributed generations(DGs)has become an obvious trend and a key feature of the development of regional distribution network in China.How to quantify the influence of DG integration on the calculation of power loss in distribution network is significant for promoting the economic benefit of power enterprises.First,a modified calculation model of theoretical power loss in regional distribution network is built based on the consideration of DG integration in this paper.Furthermore,the influences of different integration capacities and different integration locations of DGs on the calculation of reasonable power loss benchmark in regional distribution network are analyzed.Finally,the distribution of the reasonable power loss of regional distribution network at different voltage levels are calculated based on the specific voltage series in power supply(110/35/10/0.4)and the Matlab simulation platform.The theoretical analysis result of reasonable power loss in this paper can provide reference for the power loss management in power enterprises.
