Abstract

Wind energy systems (WES) have the potential for undesirable fluctuations due to their inherent variability as a renewable energy source (RESs). This issue may be handled by deploying an energy storage technology to stabilize the microgrid's voltage stability (ESSs). PMS is shown in this work, which is a standalone DC Microgrid (DCMG) powered wind energy conversion system with hybrid battery-supercapacitor (BSE) energy storage (SCs). The supercapacitor regulates fast-changing power surges, whilst the battery stabilizes intermediate-changing power surges in the proposed system. The wind turbine uses an MPPT control to monitor the wind speed and alter the duty ratio of the boost converter to record the maximum power point. Using bidirectional DC–DC converters, energy storage devices and the DC link may interchange power in both directions, lowering the DC bus voltage. In MATLAB Simulink, the suggested control process is implemented, and the results are shown for a variety of real-world examples and scenarios.
