“…The droop characteristics may be adjusted to have better voltage control performance as in [5]. However, in this work the slope will be fixed and the voltage reference will follow a predecided schedule where the voltage reference will change every half an hour.…”

This paper presents a voltage control method which is able to mitigate the voltage fluctuations caused by the integration of directly connected wind energy conversion system (WECS) based on induction generator (IG) into an unbalanced distribution system. Photovoltaic (PV) systems are widely spread in the distribution systems thus the proposed method takes into consideration high penetration of PV systems' effect especially voltage deviations. The method is based on the use of the available reactive power in the inverters interfaced with PV systems for voltage control. However, in the connection point (CP) with the directly connected IG based WECS, the PV inverter will be used to control the voltage, compensate the reactive power needed by the WECS and smooth the fast voltage variation caused by the wind speed fluctuations. Since the distribution system is considered to be unbalanced, the directly connected IG based WECS three-phase model has been taken into account as well as the other components three-phase model and the powerflow solution method. Simulations have been conducted on a 14-bus system with high penetration and one IG based WECS to evaluate the proposed control method.

“…Hosting capacity of the grid to PVs can be increased if active power curtailment is utilized [167]. It was shown in [171] that the reactive power margin by PVs increases if active power is curtailed which would be a useful mitigation source. is reactive power can be utilized to minimize tap operation instances of VRs or to resolve voltage quality issues such as voltage imbalance [172], voltage sag [170], or voltage fluctuations [172].…”

This paper presents a review of the impact of rooftop photovoltaic (PV) panels on the distribution grid. This includes how rooftop PVs affect voltage quality, power losses, and the operation of other voltage-regulating devices in the system. A historical background and a classification of the most relevant publications are presented along with the review of the important lessons learned. It has been widely believed that high penetration levels of PVs in the distribution grid can potentially cause problems for node voltages or overhead line flows. However, it is shown in the literature that proper control of the PV resource using smart inverters can alleviate many of those issues, hence paving the way for higher PV penetration levels in the grid.
