Dual Directional DC-DC Converter for Grid Integrated PV, Wind along with Battery System Based on Multi- Source Transformer

The green power generation such as solar, wind can also meet the load profile. The goal is to tap the output from different sources using the combination of the PV solar, battery and wind using the power electronics converters system. Excess electricity is injected into grid which charges/discharge the battery when needed. PV solar generation and battery's cycling are employed by dual-directional buck-boost converter. Wind power is used by a transformer connected dual half bridge converter. A monophase phase inverter guarantees the converted output to the grid. This system disturbs with fewer number of converters and with just six power electronics switches by whose size and cost is minimized. The control of twol dc–dc converter for grid connected PV, wind and battery configuration based on multi source transformer connected has been addressed. The primary goal is while not compromising the fundamental requirement this system balances the supply as well as the load requirements, to optimize the distribution of energy from various inputs, to regulate the supply from the green power sources that enhances stability and efficiency of the configuration. The bidirectional dc-dc converter simulation for grid connected hybrid PV, wind and battery systems utilizing multi-sources input transformer and Simulink outputs are showcased on Matlab.
