This paper discusses the inverter standards of PV systems that must be fulfill by the inverter used in grid connected PV systems focusing on THD (<5%), DC current injection, Anti- islanding detection standards. It also discusses the various inverter topologies used in grid connected PV system and their converter topologies.
There are different inverter topologies used for single phase or three phase grid connected PV systems like central inverter, string inverter, multi-string inverter, and module integrated microinverter according to their architecture or arrangement of PV modules interface with inverter and grid.
An inverter is a crucial component in grid-connected PV systems. This study focuses on inverter standards for grid-connected PV systems, as well as various inverter topologies for connecting PV panels to a three-phase or single-phase grid, as well as their benefits and drawbacks.
Higher bus voltage means lower operating current when output power could remain the same. As a result, cost of cables, inductors and heat sinks, together with total system dimension can be significantly reduced. Three-level topology is considered as the best configuration in high-power solar inverter systems.
