Maximizing Power Generation in a Hybrid Wind-Solar System Using Boost Two-Cell Switching Converter and MPPT for Grid-Connected Systems

Abstract

This This project presents a hybrid renewable energy system integrating solar, wind, and battery energy storage using an Incremental Conductance (INC) MPPT algorithm for maximum power extraction. A high-efficiency boost two-cell switching converter conditions the DC power, which is fed to a grid-connected inverter for stable AC output. The proposed system improves power quality, enhances reliability, and ensures continuous renewable power delivery under varying environmental conditions.

Introduction

The project proposes a hybrid renewable energy system integrating solar PV, wind energy, and a Battery Energy Storage System (BESS) to provide stable, continuous, and reliable power. The system addresses the intermittent nature of renewable sources by using BESS to store excess energy and supply it during low-generation periods.

Key components include:

• Boost Two-Cell Switching Converter (BTCSC): Provides high voltage gain, reduced current ripple, and improved dynamic response for efficient DC power conditioning.

• Incremental Conductance (INC) MPPT Algorithm: Ensures maximum power extraction from solar and wind sources under varying environmental conditions.

• Bidirectional Converter: Manages charging/discharging of BESS for energy balancing.

• Three-Phase Grid-Connected Inverter & UPQC: Converts DC to synchronized AC for grid integration, improves power quality, and regulates voltage and harmonics.

• Adaptive ANFIS Controller: Enhances DC-link voltage regulation and dynamic response compared to traditional ANN controllers.

Performance:
The system demonstrates effective integration of multiple renewable sources, high-efficiency power conversion, accurate MPPT tracking, and improved grid compatibility. Simulation results show stable power output, reduced ripple, and enhanced energy utilization, making it suitable for residential, industrial, and distributed generation applications.

Conclusion

The proposed hybrid renewable energy system integrating solar PV, wind power, and a battery energy storage system has demonstrated high reliability, improved efficiency, and consistent power delivery. The Boost Two-Cell Switching Converter successfully enhanced voltage gain and reduced input ripple, while the Incremental Conductance MPPT algorithm ensured accurate maximum power extraction under changing environmental conditions. The bidirectional battery interface provided intelligent energy balancing, and the three-phase grid-connected inverter maintained synchronized, low-harmonic AC injection into the grid. Simulation results validate superior transient performance, improved power quality, and enhanced system stability. Overall, the architecture is feasible, scalable, and well-suited for smart grid and renewable-dominated applications.
