Hybrid boost-cuk converter with bat-chicken swarm-optimized PI controller for photovoltaic grid systems

Recently, the reduction of greenhouse gas emissions and fuel consumption has been attended to by adopting the Photovoltaic (PV) system. Due to their intermittent nature, energy generated by PV systems is unpredictable for microgrid operation. Therefore, in this research, a novel hybrid Boost-Cuk converter is developed to efficiently increase the low voltage received from the PV system. Subsequently, the Bat-Chicken swarm optimized Proportional Integral (PI) controller is exploited to adjust the PI controller's parameters. Furthermore, the intermittency and instability of PV systems are addressed by adding a Battery Energy Storage System (BESS) to the microgrid to provide a steady and continuous power supply. This output is delivered to the grid via a Three Phase Voltage Source Inverter (3ϕ VSI), and the grid synchronization is accomplished with the aid of a PI controller. In order to validate the efficacy of the developed work, it is executed using the MATLAB/Simulink tool and compared with traditional topologies. The outcomes reveal that the developed research attains an efficacy of 93%, ensuring effective grid synchronization.
