Back to Back Converter Fed Wind Energy Integrated Smart PV Assisted Self-Lift Luo Converter for Micro Grid System

The benefits of efficient power generation and great transmission effectiveness have made Micro Grids (MGs) quite popular in recent times. The electrical grid is being expanded to include the MG and Nonlinear Loads (NL). NL employs electrical equipment to introduce harmonics into the electric grid, and MGs are coupled by Voltage Source Converters (VSCs). Sudden changes in demand, the growing usage of power technology, and the nonlinear properties of Renewable Energy Sources (RESs) are the main causes of the growth of stability issues in the MG. This research proposes a wind- and photovoltaic (PV) system-based microgrid using RESs. This system is designed to deliver uninterrupted, steady power to loads. Use of the Self-lift Luo converter stabilizes the PV input voltage which shows 9.3 voltage gain. Additionally, in order to improve the microgrid's efficiency, a PI controller is utilized to achieve a steady output from the converter that is distortion-free. To keep the DC link voltage stable, the 3Φinverter aggregates the output from the PV, wind, and batteries at one location and feeds it into the grid. MATLAB is the platform used to implement the results.
