Enhancement of Power Quality by Novel Control Method of Wind-AE-FC-BSS Based Hybrid Microgrid Under Faults on Distribution Lines

Standalone electrical power generation systems that harness wind energy are widely employed across various models in multiple locations. To maintain a balance of power within these autonomous systems, the presence of batteries is crucial. Additionally, the combination of Electrolyzer and Fuel Cell (FC) has the potential to strengthen independent Microgrid systems, leading to increased dependability and decreased overall expenses. Normally, a three-legged inverter is used to provide AC power to various loads including single and three phase load units. However, distribution power lines often experience faults. Therefore, it is crucial to implement suitable control techniques on both the AC and DC sides to uphold power quality across different operational conditions. To ensure its longevity, the turbine speed cannot be restored after a malfunction takes place. Consequently, an updated Maximum Power Point Tracker (MPPT) controller is employed to ensure the wind system operates effectively during faults occurring on the distribution lines. Additionally, a novel inverter control technique is introduced to restrict the current flow in the inverter legs during a fault condition. This study showcases the results of MATLAB-Simulink simulations to validate the proposed approach.
