摘要

Abstract

In the context of today's "Carbon peaking and carbon neutrality goals" goals

the demand for power quality in the power grid is constantly increasing. With the integration of various devices sensitive to power quality into the grid

such as communication or instrumentation equipment

there are stricter requirements for the harmonic content of inverter output power. Therefore

it is necessary to strengthen the research on inverter harmonic interference control strategies to improve power quality and meet grid access standards. At the same time

due to geographical limitations and other factors

many grid connected inverters are far away from the main power grid

resulting in weak and complex grid interfaces

which can lead to non-ideal grid environments such as background harmonics and weak electricity grids. This can cause problems such as grid current distortion and low-frequency oscillation

threatening the safe operation of equipment. Therefore

further research is needed on the stability control strategy of inverters under normal operating conditions and non-ideal grid environments.
