Grid-connected photovoltaic inverters: Grid codes, topologies and
This paper focuses on PV system grid connection, from grid codes to inverter topologies and control issues. The need of common rules as well as new topologies and
In utility scale in solar projects, the POI is a point of interconnection for clean energy into the grid. A well-integrated POI means that the project is set to operate within the set requirements and provisions, operate safely and provide power effectively.
Without a POI, the modern solar farms still cannot supply power to the electric grid. It is an essential part of a solar setup that guarantees smooth flow of power in the system. The base of a utility scale solar project is a well-designed Point of Interconnection (POI).
Location: The point of interconnection for solar can be at the main service panel (for residential or commercial systems) or at a utility substation (for larger-scale solar farms). Grid Connection: At the POI, the AC power generated by the solar system (after being converted from DC by the inverter) is synchronized with the grid.
It's the actual physical link that enables energy to move from a solar farm to the utility grid and into the wider network. Without a POI, the modern solar farms still cannot supply power to the electric grid. It is an essential part of a solar setup that guarantees smooth flow of power in the system.
