A PV dispersed generator: a power quality analysis within the IEEE 519

It is envisaged that the use of environmentally clean photovoltaic (PV) dispersed generation will become more widespread in the near future due to advances in PV technology which will lead to cost reductions. This paper summarizes the results of a power quality study performed on a rural distribution feeder having a PV generator and nonlinear loads in order to understand the effects that inverter-interfaced PV dispersed generation have upon the quality of electric power. Different interpretations for the harmonic distortion limits set in the IEEE 519-1992 standard are considered. This paper also includes a statistical analysis of all measurements recorded with the help of two power quality monitors, an evaluation of the results from a connection/disconnection test, and harmonies simulation results
