Abstract

This bachelor thesis deals with the wind and photovoltaic power stations, its function and principles. This work deals with the issues of wind speed, wind engines, further problems with the principles of solar photovoltaic and basic properties of photovoltaic panels. It informs about the current state of wind and solar energy in the world and in the Czech Republic, deals with sites suitable for further expansion of these resources. Also it describes the conditions for the connection of renewable sources into the electricity system under and PPDS standard ISO 50160th. At first the analysis of the chosen voltage parameters from wind power is realized in the practical part. The voltage fluctuations and the long-term rate of the flicker were analyzed. The last part is focused on the biggest problem of the photovoltaic powers on the quality of voltage and it is a long-term severity of flicker.
