Hybrid whale artificial bee colony optimized improved Landsman converter for renewable energy-based microgrid application

A major challenge with the integration of renewable energy sources (RES) into microgrids is their inherent variability and intermittency, affecting the power supply's reliability and quality. Photovoltaic (PV) and wind power conversion systems (WECS) are two examples of RES. The hybrid optimization and control techniques addressed in this work contribute to stable, reliable and efficient microgrid operation, which is essential for the successful integration of RES and the overall resilience of energy systems. Enhancing a PV system's performance within a hybrid energy microgrid is the main goal of this effort. Microgrid components consist of a PV system, a doubly fed induction generator (DFIG)-based WECS and a supercapacitor because power generated from PV and WECS sources is intermittent. To effectively manage the PV system's output, a control strategy is employed using an improved Landsman converter and a hybrid whale artificial bee colony optimization (WABCO)-based proportional-integral (PI) controller. Pulse width modulation (PWM) rectifier coupled to the WECS produces a DC output that is stabilized with the help of the PI controller. A synchronous PI current controller approach is also utilized to synchronize grid voltage. The proposed control methodology is validated through comprehensive simulations conducted in MATLAB, demonstrating the dependable and consistent operation of the designed microgrid.
