Abstract

Low Voltage residential demand is characterized by the aggregation of each individual load connected in a dwelling. This paper analyzes different load models described in bibliography for aggregated residential loads by taking into account their nonlinear behaviour in order to assess harmonic levels in distribution networks. The implementation of these models in the simulation software OpenDSS is also described. A comparison of the different load models is addressed in two different networks: the simple IEEE 4 buses test feeder and the more complete IEEE Europe Low Voltage test feeder. Conclusions are extracted about the performance of each model for their application to more complex harmonic assessments.

基于OpenDSS的住宅综合负荷谐波分析的非线性负荷建模
低压住宅需求的特点是连接在住宅中的每个单独负载的集合。为了评估配电网的谐波水平,本文考虑了综合住宅负荷的非线性特性,对文献中描述的不同负荷模型进行了分析。并描述了这些模型在仿真软件OpenDSS中的实现。在两种不同的网络中对不同的负载模型进行了比较:简单的IEEE 4总线测试馈线和更完整的IEEE欧洲低压测试馈线。总结了各模型的性能,并将其应用于更复杂的谐波评估。
