What is constant power control in a PV inverter?
In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. . Of these, constant power control is primarily utilized in grid-connected inverters to control the active and reactive power generated by the PV system .
Why do inverters act as a constant current source?
Most of inverters in the grid are based on constant current control where inner current control loop tries to limit the current. Hence acting as a constant current source. I was wondering how control philosophy will be difference if we were to model the same inverter as a constant voltage source?
How do inverters affect a grid-connected PV system?
For a grid-connected PV system, inverters are the crucial part required to convert dc power from solar arrays to ac power transported into the power grid. The control performance and stability of inverters severely affect the PV system, and lots of works have explored how to analyze and improve PV inverters’ control stability .
What is the control performance of PV inverters?
The control performance of PV inverters determines the system’s stability and reliability. Conventional control is the foundation for intelligent optimization of grid-connected PV systems. Therefore, a brief overview of these typical controls should be given to lay the theoretical foundation of further contents.
