6 FAQs about [Photovoltaic power station motor becomes generator]

How does a PV generator work?

By controlling the instantaneous three-phase inverter output voltages v a, v b and v c, the PV generator controls the active power output and the reactive power interchanges with the external grid.

Why should PV generators be integrated into the grid?

With the increased integration of PV generators into the grid, the system operators start to require PV generators have capabilities to stay online during the fault, and provide the active power and the reactive power supports when being required to do so.

What makes a PV generator different from a conventional power system?

However, different from the conventional dynamic components in a power system (NERC, 2010), such as fuel/hydro generators or induction motors, PV generators are built with power electronics technologies.

How is a PV generator modeled in a power system steady state study?

A PV generator is modeled as a constant active power and reactive power source in power system steady state studies. When PV generation changes due to the ambient environment, the power system steady state studies do not investigate the transients of the power system caused by the change in PV generation.

Why do we not model PV generator as active power and reactive power source?

The reason of not modeling the PV generator as an active power and reactive power source even though the outer loop control tries to trace the active power and reactive power to their reference values is because the protection block might be activated to override the active power and reactive power control.

Is a photovoltaic generator a PQ node?

Unlike a conventional generator that is often modeled as a PV node (set the generator’s terminal voltage and its active power output constant), a photovoltaic generator is operated as a PQ node (set the photovoltaic generator’s active power and reactive power outputs constant).
