Reliability Models of Generating Units Utilizing Renewable Energy Sources

The article presents the ways of modelling unstable (variable) renewable energy sources in calculations of reliability of power systems. Basic reliability models of generating units have been described. Two reliability categories, which are related to variable renewable energy sources, were distinguished: structural reliability and production reliability. Algorithms of the proceedings in creating a multi-state reliability model of wind power plants, solar power plants and small hydroelectric power plants are presented.
