This study presents a current decomposition technique based on a novel instantaneous power theory for better power quality and reliability of a dc-grid based wind energy conversion system (WECS) used on a poultry farm. The proposed approach also offers adequate control for the parallel operation of multiple distributed generations independent of the requirement of voltage and frequency synchronisation. In addition to that, a 17-level hybrid cascaded multilevel inverter is considered and integrated by utilising a three-level flying capacitor inverter and cascading it with three floating capacitor H-bridges. The presence of single dc-link voltage facilitates the back to back operation with a reduced dv/dt ratio, common-mode voltage variation, and operations under varying load power factors and modulation index. Moreover, for attaining better power management especially in the islanded mode of operation, the battery energy storage device is incorporated. The proposed WECS has been tested through MATLAB/Simulink software simulation under various conditions to facilitate better power quality, increase the flexibility and reliability in the micro-grid operation.
