Abstract

The management of remote sites' hybrid wind-and-solar energy-powered micro grids. The battery bank is connected to a shared DC bus from the double fed induction generator (DFIG), which is the device used to convert wind energy. The conversion of solar energy takes place in photovoltaic (PV) arrays. On the common DC bus of DFIG, a DC-DC boost converter efficiently consumes solar energy. The line-side converter with drooping characteristics' indirect vector control is used to regulate the voltage and frequency. It slows the overcharging or discharging of the battery by altering the frequency reference dependent on the battery's energy level. You can run this system without using wind energy. Maximum power point tracking (MPPT) is a component of control algorithms for wind and solar systems. In addition to having external power support to charge the battery without the need for additional power, this system is designed for completely automated operation, taking into account all of the actual system conditions. The system's simulation model is created in the MATLAB environment, and the simulation results are presented in a variety of ways. Low battery charge state, imbalanced load, impervious to wind or sunlight, and non-linear. A 3.7kW wound rotor asynchronous machine and a 5kW photovoltaic array simulator are used to execute the system and produce experimental results that confirm the theoretical model and design.
