Grid-connected solar PV systems operate in two ways,the first is the entire power generation fed to the main grid in regulated feed-in tariffs (FiT),and the second method is the net metering approach. What is a grid-connected PV system? Grid-connected PV systems enable consumers to contribute. This paper aims to discuss the grid connection technology and application of solar power generation in the new power system. The basic principle and composition of the solar power generation system are introduced, and the characteristics, requirements and optimization of the grid connection. Promoting a sustainable and low-carbon energy future through the integration of renewable energy is essential, yet it presents significant challenges due to the intermittent nature of resources such as solar and wind. However, issues exist as Solar PV is only available during the daytime and reduces system inertia. In Iraq, for example, the World Bank reports a significant power distribution loss of.
