Photovoltaic inverter phase deviation
This work optimally determines volt–var curves for PV inverters, using a three-phase optimal power flow formulation (TOPF), for autonomous voltage control on low voltage feeders. The volt–var curves are found by taking the optimal reactive power settings for various load and PV active power scenarios and plotting them against the .

Different from synchronous generators, which detect the frequency deviation based on the difference between mechanical torque and electromagnetic torque, the PV inverters detects frequency deviation by means of phase-locked loop (PLL). The PLL integrated in an inverter can be either a three-phase type or three single-phase ones.
The paper develops a reactive power compensation strategy that uses distributed solar photovoltaic (PV) inverters to mitigate such voltage unbalance. The proposed strategy takes advantage of Steinmetz design and is implemented via both decentralized and distributed control.
This article provides extensive experimental evidence on the behavior of 31 off-the-shelf residential DPV inverters under different voltage phase-angle jump disturbance conditions. The undesirable behavior from DPV inverters is classified into disconnection and power curtailment.
An extensive experimental analysis of the behavior of thirty-one off-the-shelf distributed photovoltaic (DPV) inverters to voltage phase angle jump (VPAJ) disturbance is done in this paper.
