Inverter technology is the key technology to have reliable and safety grid interconnection operation of PV system. It is also required to generate high quality power to ac utility system with reasonable cost. To meet with these requirements, up to date technologies of power electronics are applied for PV inverters.
According to the survey, PV grid connection inverters have fairly good performance. They have high conversion efficiency and power factor exceeding 90% for wide operating range, while maintaining current harmonics THD less than 5%. Numerous large-scale projects are currently being commissioned, with more planned for the near future.
To meet with these requirements, up to date technologies of power electronics are applied for PV inverters. By means of high frequency switching of semiconductor devices with pulse width modulation (PWM) technologies, high efficiency conversion with high power factor and low harmonic distortion power can be generated.
The PV inverter is modelled as a constant power source, however, for fault analysis, the authors assumed the limiting current to be twice the rated current, for the worst-case scenario. The inverter current and voltage are considered in phase for unit power factor operation.
The current commercially available inverter hardware used for uninterruptible power supplies or for remote (short-term) power applications was found to be incompatible with the new requirements of a PV power system . Costs were too high and efficiencies were too low.
Unfortunately, there are few works based in experimental results of systems operating with different relative capacities, P Inv 0 / P PV 0. The most common is to find operational results in kWh/kWp, without mentioning the relationship between the inverter's capacity and the capacity of the PV generator,, .
