Another potential solution is the utilization of PV inverters for voltage control due to their control of active and reactive power generation capabilities . It is to be noted that power electronic converters based PV systems are able to provide reactive power support for their entire operational range.
The control system incorporates a maximum power point tracker (MPPT) that continuously determines the optimal power for the operational PV array. The control strategy encompasses regulating both active and reactive power, accomplished by manipulating the load angle and the magnitude of the inverter's output voltage.
The control strategy encompasses regulating both active and reactive power, accomplished by manipulating the load angle and the magnitude of the inverter's output voltage. By adjusting the reactive power injected into the grid, the controller ensures that maximum active power is fed into the grid at a unity power factor.
By optimizing the reactive power (Volt/VAr) control of smart inverters for photovoltaic (PV) systems, the method not only prevents voltage violations but also ensures that the necessary curtailment of power is fairly distributed among all PV inverters.

Olivier et al. proposed a distributed scheme for PV inverters to mitigate an over-voltage problem by controlling the reactive power of each PV unit and, if necessary, curtailing active power
The smaller the power factor becomes, the higher the reactive power, and this leads to low efficiency and greater fuel consumption in thermal plants.
