6 FAQs about [Shouhang Photovoltaic Inverter Firm Control]

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 .

How do PV inverters control stability?

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 . In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. .

How does a PV system affect power quality?

However, the control performance and stability of the PV system is seriously affected by the interaction between PV internal control loops and the external power grid. The impact of the PV system on the reliability, stability, and power quality of power systems has restricted them to further participate in power supplies with a large capacity.

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 .

How does solar photovoltaic penetration affect synchronous power plants?

The increasing amount of solar photovoltaic (PV) penetration substitutes a large portion of conventional synchronous power plants. During the peak power production period, it may lead to reduced the rotational inertia and thereby deteriorate inherent inertial response of the power system.

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.
