Control Strategies of UPQC by Adaptive Hybrid PV/PEMFC Distributed Generation System with BLDC Motor Drive

Abstract

In this concept presents the integration of photovoltaic (PV), fuel cell (FC) and energy storage systems for reliable power generation. In this system FC is used as main power source and power from PV whenever available is harvested completely with storage system compensating for power fluctuations. This topology has high efficiency, modularity and fuel flexibility. The sources in this hybrid system complement each other very well against environmental variations and load variations. UPQC is used to mitigate the power quality problems like harmonics and sag. The power fed is linked through common DC link and maintains constant real power exchange. The DC link is connected through the reactor. The BLDC motor is suited to many low- and medium-power applications ranging from household appliance; medical equipment; position actuators; heating, ventilation and air conditioning; motion control; and transportation. BLDC motors are synchronous motors having permanent magnets on the rotor and three phase windings on the stator. BLDC motor drives have gained importance in the last decade due to power quality improvements. The proposed concept can be implemented to hybrid PV/PEMFC distributed generation with bldc motor using Matlab/ Simulink software.
