DDSRF Theory for Power Quality in UPFC Applications

The electrical method's power quality is critical for businesses, factories, and residential applications. Users and utilities have been more concerned about the quality of power as the demand for high-quality electrical power has increased, as has the number of distortion loads. In this paper proposed the Decoupled Double Synchronous Reference Frame (DDSRF) model for the power quality in unified power flow controller (UPFC) applications also the FACTs parts that controls the communication line's active and reactive power flow. This article attempted to improve power superiority by using a fuzzy logic controller (FLC) and boost converter with solar system founded UPFC to regulator both active and reactive supremacy movement, adjust power issue, control line power, and increase passing steadiness. The DDSRF generates an annular harmonic that is diametrically opposed to the load harmonic. The frequency is then injected into electricity systems, reducing the influence of harmonics. The THD value comparison has the value of 2.2% using DDSRF theory.
