What is solar photovoltaic (PV) power generation?
Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
What is a solar PV power plant?
Solar PV power plants consist of several interconnected components, each playing a vital role in converting solar energy into usable electricity. Comprised of photovoltaic cells made of silicon, these panels capture sunlight and initiate the photovoltaic effect.
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 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 model is used to simulate a solar PV generator?
The WECC generic PV generator model was used and the simulation analysis was conducted in DIgSILENT PowerFactory.
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.
