Power Quality Analysis of Integration Photovoltaic Generator to Three Phase Grid under Variable Solar Irradiance Level
Abstract: Objective of
research is to analyze the influence of solar irradiance and integration of photovoltaic
(PV) generator to power quality of three phase grid on the constant temperature
and load,based on changes in some level of integration of PV generator. Power
quality aspects studied arefluctuation or changing, and harmonics of voltage
and current on eight scenarios PV generator connected to three-phase grid,
using passive filter circuit model double band pass (double tuned). Research
shows that voltage and current values on the PCC bus before use double tuned
passive filter on the condition only connect single generator is still stable.
However, if the PV generator connected to the three phasegrid, amounted to more
than one generation, voltage and current grid becomes unstable (fluctuation).
At the level of solar radiation remains, the greater number of PV generators
connected to the grid threephase, then the values of voltage and current THD
increases. At the level of solar irradiance increases, average THD of voltage
and current grid also increased. Avarage THD of voltage and current grid is reduced
after double tuned passive filter installed. Therefore, double tuned passive
filter able to improve profile of voltage and current THD grid as a result of
the integration of a number of PV power generators in three-phase grid
according IEEE Standard 519-1992.
