摘要：In the paper an estimation of the correlation between power generation from wind and photovoltaic farms distributed over a large area has been presented.The climatic and morphological conditions for the considered area are similar to the Polish conditions.The initial analysis of data provided by distribution system operators indicates that a negative correlation between wind and PV energy generation exists when a longer period of averaging is assumed.Additionally,the maximum value of generated power has never reached the level of installed capacity.Considering the system,where a significant number of wind and photovoltaic farms are installed,an assumption that total generation sources capacity is achievable can lead either to grid curtailments or to grid development overinvestments.
