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.
Are grid-connected PV generators a good investment in China?Indeed, the installed capacity of grid-connected PV generators in China has ranked the first in the world since the end of 2015, and still shows a strong growing trend (Ding et al., 2016, Kang and Yao, 2017, National Energy Administration of the People's Republic of China, 2019).
How to validate a model of electric power generation system?Among the modeling and application practices, the modeling validation should be given special attention since most of the literature uses only digital simulations to validate the model and the algorithm. Laboratory tests have been reported in some works on modeling the electric power generation system, such as PV panel control.
Can PV generator be validated?Although modeling PV generator is widely reported in the literature, the validation work on various models so far, however, is still limited. Most of the reported modeling work uses the digital simulation to validate the developed model while only a few report the field test results.
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.
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 contr
