摘要 当前,新能源发电技术快速发展,电网面临诸多新挑战。其中,电网谐波作为一项重要的电能质量评价指标,正伴随新能源发电量占比的增加而呈现出愈加严重的趋势。针对谐波问题,传统的主动谐波治理方法常通过加装有源电力滤波器(APF)实现,而逆变器作为新能源发电与电网之间的重要接口,除并网功能外也具备谐波治理能力。因此,本文提出一种新型的逆变器并网-谐波治理综合控制方法,可以根据实际需求进行并网、谐波治理功能的切换与融合,并优化了容量受限条件下的谐波治理策略。最后,通过Matlab/Simulink仿真软件进行仿真分析与验证,结果表明此方法可以改善电能质量,并降低谐波治理的成本。

Abstract:Currently, with the rapid development of renewable energy, the power grid faces many new challenges. Harmonics, as an important indicator of power quality, are becoming increasingly severe with the growth of the proportion of renewable energy in the total power generation. Traditional active harmonic control methods often involve installing active power filters (APF). However, inverters, serving as a crucial interface between renewable energy generation and the power grid, also possess harmonic control capabilities. Therefore, this paper proposes a novel integrated method for inverter grid-connection and harmonic control, which allows for the switching and integration of grid-connection mode and harmonic control mode based on actual needs. Furthermore, the harmonic control strategy is optimized under capacity-constrained conditions. Finally, simulation analysis and verification are conducted using Matlab/Simulink software. Applying this method in practical engineering can effectively improve power quality and effectively reduce the cost of harmonic control.
