Description
Summary:The rapid increase of higher photovoltaic (PV) penetration has prompted countries to specify fixed limits of percentage reactive power and power factor contribution to the grid. This concept of limiting the power factor and reactive power could also be good for distribution lines in managing the voltage and reactive power balance for inductive and non-inductive loads. However, the variation of irradiance and temperature can fluctuate the power at the weak grid. In this study, a three-phase Grid-connected PV inverter simulation is made to investigate the effect of irradiance and temperature on loads performance when reactive power compensation regulates constant power factor and constant reactive power to the weak grid. A 12 kW PV power is proposed to inject reactive power in two cases. Case one maintains the power factor constant at 0.95, while case two maintains the reactive power constant of 3.945 kVAR. The simulation results show that fluctuating irradiance subsequently fluctuated the absorbed powers of an inductive load of 3 hp and a purely resistive load of 4 kW.
