一种具有多目标优化设计的简化经济型双电容统一电能质量调节器

A simplified cost-effective dual-capacitor unified power quality conditioner (DuC-UPQC) is proposed. It could maintain sinusoidal standard load voltage and in-phase grid current, obtain reduced dc-link voltage, improve modulation indexes, achieve active power balance between inside dynamic voltage restorers and active power filters. Compared to existing methods, DuC-UPQC is cost-effective as less ...
