How do I model a PV power plant?
In accordance with the WECC PV Plant Power Flow Modeling Guide4, PV power plants must be represented by a simplified system consisting of one or more equivalent generators and unit transformers, equivalent collector system, substation transformer, and plant-level reactive support system, if present.
What is a three-phase grid-tied PV generator?
Three-phase PV generators, such as the utility-scale solar power plants, are often connected to the high voltage sub-transmission or transmission networks. This paper focuses on the dynamic models of the PV generator for power system dynamic studies, thus will concentrate on the three-phase grid-tied PV generator.
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.
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).
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 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.
