Fuzzy logic controller of photovoltaic panel-unified power quality conditioner with voltage compensation and stability

<span lang="EN-US">The intensive use of non-linear loads is further contributing in the increase power quality problems. They cause voltage distortions and current harmonics an electrical distribution network. To minimize these problems, unified conditioner (UPQC) used. The intermediate circuit this filter can deviate from its source during a transient event harmonic disturbance (voltage dip) or connection disconnection polluting loads. In particular point operating time, stabilization dc-bus compensation ability necessary to maintain around reference. combination UPQC with photovoltaic (PV) system connected element two converters DC bus (DC Link) adequate solution. fitted fuzzy MPPT controller regulated by algorithm (P O) control boost converter. This converter controlled logic related capacitor terminal UPQC. simulation results show that based on proposed be used for protection network.</span>
