High power multifunctional inverter

Unlike traditional inverters, multifunctional inverters sacrifice their own output current quality to perform cooperative control over the energy quality in the system. However, further discussion is needed on how to allocate power and perform real-time control.

Considering the distribution and structural characteristics of the current new-type sources and loads, a multifunctional inverter power quality coordinated control strategy based on comprehensive evaluation is proposed.

Multilevel inverters are gaining significant traction in high-power, medium-voltage applications due to their distinct advantages over conventional two-level inverters. These inverters offer improved power quality, reduced harmonic distortion, lower voltage stress on switching devices, and higher efficiency.

2. Literature Review Multilevel inverters have gained significant attention in recent years due to their ability to improve power quality, reduce total harmonic distortion (THD), and enhance efficiency in high-power applications.

This paper proposes a coordinated optimization control strategy for multifunctional inverters based on comprehensive weight evaluation. This strategy aims to address power quality issues such as voltage deviation, harmonics, and three-phase imbalance in the distribution network through the coordinated control of multifunctional converters.
