摘要：With increasing applications of nonlinear and electronically switched devices in distribution systems and industries, Power-Quality (PQ) problems, like harmonics, neutral current elimination, reactive power has become an unavoidable issue. The Unified Power Quality Conditioner (UPQC) of shunt and series inverter having a common Direct Current (DC) link. The UPQC in distribution has made it possible to mitigate the following problems effectively. The UPQC has been realized by Voltage Source Inverter (VSI). The controlling algorithm determines the production of controlling signals which is used by the VSIs for the generation of their gating signals. The variation of performance of the device occurs with the different controlling algorithms .This paper proposes the comparison of performance of two mainly used algorithms namely Particle Swarm Optimization (PSO) and Genetic Algorithm (GA). The two controlling algorithms are used in a Fuzzy Controller (FC). In addition to this Synchronous Reference Frame (SRF) theory with modified Phase Locked Loop (PLL) is used in both cases for better performance. The main PQ issues concentrated in this paper relates to reactive power compensation, harmonics elimination and neutral current elimination. The performance is being investigated in an IEEE 118 bus system. Simulation outputs have been obtained through MATLAB/SIMULINK.
