DDSRF Theory based Solar assisted RELIFT Luo Converter with UPQC used in Voltage Enhancement
Authors: , ,
Abstract: As PV system-based power generation and sensitive non-linear loads are integrated more
frequently, there is a greater need for enhanced Power Quality (PQ) in distributed power systems. In this work,
a specialized power device known as a Unified Power Quality Conditioner (UPQC) is proposed to improve the
PQ of the network overall. Source and load side PQ related issues are addressed using series and shunt
compensators in order. The PV system can provide active power to the load in the presence of the shunt
compensator. Using the Re-lift Luo DC-DC converter, the output voltage of the PV system is increased which
further improves the voltage gain and efficiency of the intended converter. An FLC is utilized to adjust the
gain values of the pi Controller which further improves the voltage profile of the UPQC. Decoupled Double
Synchronous Reference Frame (DDSRF) theory is utilized to produce the reference current and voltage values
to improve the current-voltage profiles at the source end. To attain the controlled responses of the shunt and
series compensators Type-2 FLC (CT2FLC) based controllers are utilized.
