The photo voltaic technology is one of an emergent technology, helping in the production of electrical energy. The demand for this technology has been increased globally due to the rapid increase in population growth. This rapid increase requires an emergent technology which helps in providing solution for the electric utilities. Solar Voltaic system helps in assisting the existing power system. This system is a kind of distributed power generation system. This is one of the best technologies to provide solution for present scenario. In this paper, the double stage three-phase grid-connected solar inverter is explained. The complete modelling is presented in MATLAB-Simulink environment for the switching model of a grid connected solar inverter. MPPT technique is also used to track the maximum power in the simulation. Phase lock loop technique is used to synchronize the PV system with a certain phase. The importance of the inverter modelling, outer voltage loop, inner current loop considering the connection requirements, the double stage controller is fabricated. The complete model is designed in the MATLAB environment. The present article thoroughly examines the two-stage three-phase grid-connected photovoltaic (PV) system. The paper describes the modeling of a single PV system's switching mechanism in phases. It emphasizes the importance of inverter control to meet future connectivity requirements. The double loop controller is used to regulate both the boost converter and inverter. Vector-oriented and feed-forward control techniques are employed to create the inverter controller. Additionally, the article discusses the significance of extracting positive and negative sequences. In the MATLAB environment, the entire model is created. Solar PV systems are classified as distributed generation since they aid existing power systems in meeting electricity demand for load changes. In this paper, a stand-alone PV system is connected to a three-phase grid, which includes a PV array, the Perturb and Observe (P and O) Maximum Power Point Tracking (MPPT) technique for tracking maximum power from the PV array, and the Duty Cycle adjustment for switching pulses to the Boost Converter's High-Level Switch. With Pulse-Width Modulation (PWM) control, the 2-level inverter converts DC to AC. The Phase Lock Loop approach is used to synchronize the Standalone PV system with the grid at a specific phase angle and frequency. According to load variations, the control circuit is designed to supply active and reactive electricity to the load from a standalone PV system and the grid. This study shows a three-phase dual-stage inverter-based grid-connected PV system in a centralized arrangement. The three-phase series resonant converter is chosen for the DC-DC stage because of its advantages. It is, however, insufficient for MPPT because its efficiency is highly dependent on the implemented deadtime and switching frequency. [ABSTRACT FROM AUTHOR]
