dc.description.abstract This project report analyzes and provides design methodology of Grid-Tie-Inverter using the Arduino mega 2560, H-bridge circuit and DC-DC converter. This study examines the development and operation of a 3-phase grid-tie inverter with feedback control system and phase-locked loop (PLL) in the stationary frame of reference (α,β) and synchronous frame of reference (𝑑 − 𝑞). The result reveals an intriguing and crucial aspect of three-phase grid-tied inverters: they convert DC to AC and synchronize their voltage, current, frequency, and phase with the grid in a regulated and efficient way. Furthermore, this study demonstrates grid synchronization behavior, in which the frequency range is determined by the PLL bandwidth and the inverter power rating. As an example, under poor grid conditions, a change in PLL bandwidth might cause the inverter system to become unstable as a result of this behavior and condition is handled by grid tie inverter. The suggested grid tie inverter model may be used to investigate harmonic resonance and instability concerns. The analysis is confirmed by simulations and experiments measurements. Everyone in this country is aware of the energy catastrophe that our country is experiencing as a result of the exhaustion of energy-producing resources such as fossil energy, natural gas, and coal reserves. Renewable energy technologies are a solution that can meet our electrical demands while also being environmentally beneficial (Solar, Wind, Biomass etc.). Solar energy is by far the most abundant renewable energy resource, and our country is fortunate to have it. Renewable energy resources do not, however, produce as much electricity as human’s demand. These resources are not particularly enough until we make it efficient. However, as technology advances, several strategies, such as the Maximum Power Point Technique (MPPT) and Zero-Crossing Detection (ZCD), have been developed to enhance the energy production of renewable sources of energy. As a result, the project's goal is to design a system that can efficiently produce electric energy from any renewable DC source to meet our daily energy needs, as well as energizing the National Grid if excess energy is produced for the solar cells en_US
