Fuzzy multi-objective technique combined with VCS algorithm for unified power quality conditioner based on hybrid power source PEMFC/SC

摘要: Abstract This paper is proposed to establish an optimal control method for UPQC (Unified Power Quality Conditioner) improve power quality and manage effectively equal sharing between shunt series inverter of under electrical faults condition. The modeled protect sensitive load from source side voltage disturbances nonlinear conditions. A hybrid generator that integrates a proton exchange membrane fuel cell (PEMFC) as the main energy super capacitor (SC) secondary feed FACT device. In this work, new strategy presented considering sag, factor total harmonic distortion (THD) multi-objective controller. For purpose, powerful algorithm named virus colony search (VCS) used determining coefficients PI controller UPQC. By using fuzzification process objectives function, suitable fitness function established optimization method. From simulations, it can be seen results obtained by are best attractive compared other Consequently, effective outstrips strategies.
