Optimal Voltage Unbalance Suppression Control Using PV Inverter
Distribution networks exhibit unbalance issues due to arbitrarily connected devices. This article advances the control strategy of optimal voltage unbalance (VU) suppression using
Curtailment can be employed to actively limit the power output of a PV system by adjusting the operating voltage and current in the systems' inverter . This should limit the power output of a PV system when the inverter experiences a quick surge in its power output.
An assessment of the impact of PV power output on the power quality in the low voltage grid. A PV penetration of 40% will already cause problematic voltage fluctuations in the considered low voltage grid. A numerical comparison among three different regulation strategies for mitigating rapid voltage fluctuations.
The power output of a PV system is directly dependent on the solar irradiance that is received in the plane of the PV array. Shading caused by transient clouds can therefore lead to major changes in the power output in mere seconds.
All other PV power profiles are generated by considering inverse distance weighted interpolation. Such method has been applied to estimate the PV power output profile in other studies, albeit for other temporal and spatial resolutions, .
