Abstract - This paper presents a modeling and simulation
This paper presents a modeling and simulation study of a solar PV system with an MPPT-based inverter and grid synchronization. The proposed system consists of a DC-DC boost converter, a MPPT-based inverter, and a grid-connected transformer. The MPPT-based inverter uses a fuzzy logic algorithm to track the maximum power point of the solar panels, while the grid synchronization is achieved using a phase-locked loop (PLL) and pulse width modulation (PWM) technique.

1. INTRODUCTION The increasing demand for clean and renewable energy has resulted in the development of solar photovoltaic (PV) systems as an alternative to traditional power generation methods. Solar PV systems can generate electricity directly from sunlight, and when connected to the grid, can supply electricity to the utility grid. However, the efficiency of solar PV systems is heavily dependent on the ability to extract the maximum power from the solar panels, which is influenced by various factors such as temperature, irradiance, and shading. Therefore, maximum power point tracking (MPPT) algorithms are used to optimize the output power of the solar PV system.

2. PV SYSTEM / SOLAR POWER SYSTEM Photovoltaic (PV) systems have become a popular choice for renewable energy generation due to their ability to convert sunlight directly into electrical energy. The heart of a PV system is the solar panel, which consists of a collection of photovoltaic cells that generate direct current (DC) electricity when exposed to sunlight. The output voltage of a PV panel depends on various factors such as the intensity of sunlight, temperature, and load impedance. In order to extract maximum power from the PV panel, a maximum power point tracking (MPPT) algorithm is used in conjunction with a DC-DC converter.
In addition, grid synchronization is crucial to ensure that the power generated by the solar PV system is of high quality and does not cause any disturbances in the grid. Therefore, it is necessary to develop an inverter that can synchronize the output power of the solar PV system with the grid.
