OPTIMIZED GRID LINKED PV SYSTEM WITH ZETA CONVERTER FOR ENHANCED EFFICIENCY

The need for efficient converters is essential for the incorporation of solar PV systems with grid infrastructure to control voltage and maximize energy transmission. Using a Zeta converter and the Incremental Conductance (INC) MPPT algorithm, this study explores a grid-linked photovoltaic scheme. The Zeta converter plays a crucial role in stabilizing DC link voltage despite fluctuating solar irradiance, considering a consistent output between 290V and 600V.Through dynamic tracking and maintenance of the PV array's MPP, the INC MPPT approach improves system efficiency. In addition to optimizing energy extraction, this integrated strategy guarantees steady power transmission to the grid, reducing fluctuations and enhancing overall performance. The proposed scheme demonstrates significant improvements in voltage regulation, energy efficiency, and reliability, making it a viable solution for modern renewable energy applications.However, designing an optimal control strategy for the zeta converter is essential to balance the efficiency, transient response and voltage stability. Its ability to regulate voltage effectively enhances the performance of photovoltaic systems, preventing fluctuations from affecting downstream components. Proposed Simulation outcomes provide the efficacy of the proposed system under dynamic operating conditions, highlighting its effective power transfer. This study provides a comprehensive framework for implementing Zeta converters in Grid-linked PV schemes, bridging the gap between renewable energy generation and grid stability.
