The present work proposes a method for real-time compensation of the unintended reactive power,which decouples the reactive power from the active power of a photovoltaic inverter.
The flow of reactive power in the transmission line increases the total current and Joule losses in the line. In addition, a large proportion of unintended reactive power may destabilize the inverter in very weak grids. Consequently, the unintended reactive power imposes limitations to maximum active power feed from the PV inverter.
The present work proposes a method for real-time compensation of the unintended reactive power, which decouples the reactive power from the active power of a photovoltaic inverter. Based on real-time measurement of the grid impedance, the unintended reactive power is estimated and autonomously compensated in the inverter.
Power generation flowing through the transmission line causes unintended flow of reactive power to the grid side, as the transmission reactance consumes reactive power. Thus, the grid-side reactive power becomes coupled with the active power production of the photovoltaic inverter, which fluctuates along with irradiance conditions.
Based on real-time measurement of the grid impedance, the unintended reactive power is estimated and autonomously compensated in the inverter. The method removes the fluctuating reactive power component, while still permitting unrestricted manual control of the reactive power.
Manual reactive power control during autonomous operation Most of the new PV inverters are capable of reactive power support. The proposed autonomous compensation method defaults the grid-side reactive power to zero, but does not interfere with external reactive power control.
