| Abstract: | The irradiance model, the ambient temperature model, and the random outage model of photovoltaic components are reviewed in the reliability modeling of photovoltaic power generation. The existing photovoltaic power generation and its reliability assessment methods and reliability indicators are summarized. The effects of photovoltaic power generation on the distribution network and power generation system are reviewed. It is pointed out that more energy storage devices, wind-solar hybrid power generation and wind-light storage technology are three methods to improve the reliability of photovoltaic power generation and its power system. Finally, the paper predicts the future research trends concerning photovoltaic power generation and the assessment of its reliability in the power systems. |
