Introduction to renewable energy sources. Small hydro power plants: hydro-potential, types of turbines and generators, the ways of regulation. Wind power stations: the potential of wind and its determination, the types of windmills, generator types and connection of wind power stations into windmill parks. Solar power plants: solar radiation, solar-electric energy sources, and connection of solar sources. Gas power plants: potential gas resources, gas turbines, the use of gas power plants in combined and direct energy transformations. The influence of renewable energy on the environment. The principles of economic evaluation of renewable energy sources (investment, exploitation costs and profit). A part of the course is being realized through individual research study in the field of renewable energy. The research study includes the overview of bibliography, organization and performance of experiments and statistical data processing, numerical simulation, writing of papers closely related to scientific and educational area of the doctoral dissertation topic.
