        abstract = {This paper presents the design and analysis of a two-stage single-phase grid-connected solar photovoltaic (PV)system incorporating a simplified power regulation strategy. The proposed system consists of a DC-DC boost converter for maximum power point tracking (MPPT) and a DC-A Converter for efficient grid integration. A simplified control approach based on a Proportional-Integral-Derivative (PID)controller is employed to regulate the DC-link voltage and ensure stable power transfer between the PV array and the utility grid. The control strategy reduces computational complexity and minimizes the number of sensors compared to conventional methods while maintaining fast dynamic response and high steady-state accuracy. The system is modeled and simulated under varying irradiance and load conditions to evaluate its performance. Results demonstrate improved voltage stability, reduced harmonic distortion, and effective grid synchronization. The proposed configuration offers a cost-effective, reliable, and efficient solution for residential and small-scale renewable energy applications, contributing to sustainable energy generation and improved power quality.},
