6 FAQs about [Voltage of generators in large photovoltaic power plants]

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.

How does a PV power plant regulate voltage?

Voltage regulation actions: the PV power plant is required to help maintaining the grid voltage level. A minimum reactive power capability of the PV power plant is established. Additional ancillary equipment, as FACTS devices, can help to reach the capability limits.

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.

What are the different types of PV generators?

Based on where the generated electric energy is used, a PV generator also can be categorized into a stand-alone PV system or a grid-tied PV generator. A PV generator can also be classified into a single-phase system or a three-phase system.

Can large-scale photovoltaic power plants be integrated into power networks?

Integration of Large-Scale Photovoltaic Power Plants into Power Networks to Maintain System Stability. In: Gonzalez-Longatt, F.M., Rueda Torres, J.L. (eds) Modelling and Simulation of Power Electronic Converter Dominated Power Systems in PowerFactory. Power Systems.
