The system comprises solar PV panels, wind turbines, batteries, inverters, converters, and various control mechanisms. Each component plays a vital role in harnessing renewable energy and ensuring efficient power distribution.


Wind Generation:

The wind turbine, equipped with a Permanent Magnet Synchronous Generator (PMSG), converts wind energy into mechanical torque. The generated torque is then utilized to produce electrical power, which undergoes rectification and voltage boosting via a boost converter.


Solar PV Integration:

Solar PV panels, arranged in series and parallel configurations, harness sunlight to generate electrical energy. Through Maximum Power Point Tracking (MPPT) algorithms, the system optimizes power extraction from the PV panels, ensuring maximum efficiency under varying irradiation conditions.


Battery Energy Storage:

Battery banks store surplus energy generated by the solar PV and wind systems, facilitating energy balancing and grid stability. Bidirectional converters enable charging and discharging of batteries, ensuring seamless integration with the grid and load demands.


Grid Integration:

The three-phase inverter facilitates grid integration by converting DC power from the PV and wind systems into AC power suitable for grid connection. Advanced control algorithms ensure precise regulation of voltage and frequency, maintaining grid stability and power quality.


Operational Control:

The system's operation is governed by sophisticated control algorithms, including MPPT for PV and wind systems, current control for inverters, and power balancing between generation and load. These control mechanisms ensure optimal performance and efficient energy utilization.


Performance Analysis:

Real-time monitoring and analysis of system parameters, such as PV and wind power generation, battery state-of-charge, and grid interaction, provide insights into system performance and optimization opportunities. Detailed simulations and data visualization enhance understanding and facilitate decision-making.


Conclusion:

The integration of solar PV, wind, and battery systems into a three-phase grid-connected configuration represents a significant advancement in renewable energy technology. This holistic approach enables sustainable power generation, grid stability, and energy independence, paving the way for a greener and more resilient future.
