摘要： 针对新型电力系统背景下并网变换器的谐波抑制问题,阐述了并网变换器滤波器设计和基于优化脉宽调制（Pulse Width Modulation,PWM）谐波抑制方法的特征与问题,提出了一种多目标优化特定谐波抑制（Selective Harmonic Mitigation,SHMPWM）的方法,得到了特定谐波消除（Selective Harmonic Elimination,SHEPWM）的全部解集与特定谐波抑制的多目标优化解,同时对比了SHEPWM与SHMPWM的谐波分布规律与抑制效果,为并网变换器的谐波抑制与优化提供了新的解决思路与对策。

Abstract: Aiming at the harmonic suppression of grid-connected converters under the background of new power system,the characteristics and problems of the design of grid-connected converters filter and harmonic suppression methods based on optimal PWM modulation are described. A multi-objective optimization method based on selective harmonic mitigation （SHMPWM） is proposed,and the whole solution set of selective harmonic elimination （SHEPWM） and the multi-objective optimization solution of SHMPWM are obtained. The harmonic distribution and suppression effect of SHEPWM and SHMPWM are compared,which provides a new solution and countermeasure for harmonic suppression and optimization of grid-connected converters.

Key words: new power system, grid-connected converter, selective harmonic mitigation, multi-objective optimization
