Overview of Harmonic Analysis and Control of Charging Machines Connected to Distribution Networks
摘要
Abstract
In the past two years,the penetration rate of electric vehicles(EV)has skyrocketed,and the scale of distributed generation(DG)entering the grid has led to an increase in the harmonic impact of EV connected to the distribution network.Therefore,a detailed analysis of the harmonic propagation law of EV access to the distribution network and the proposal of more comprehensive harmonic control measures are important issues that urgently need to be addressed in the current power field.Firstly,the causes of harmonic generation are analyzed and summarized from the perspective of the charging machine model.Then,the harmonic characteristics of single and multiple different types of charging machines are analyzed and summarized from the aspects of charging machine rectifier structure,charging strategy,interaction with other harmonic sources in the power grid,and selection of common connection points.Finally,starting from three objects:charging machine manufacturers,charging site service providers,and the power grid,a comprehensive review is conducted on the existing measures to control the harmonic generation of EV connected to the distribution network.The shortcomings of various harmonic control measures at the current stage are pointed out,and future harmonic control measures are discussed in combination with the development trend and characteristics of China's new distribution network.The research results can provide useful references for the study of power quality in the integration of EV into the distribution network.关键词
