Abstract
The objective of this thesis was to calculate capacity value of wind power in Finland in several different situations, for example with different wind penetrations and different generation adequacy levels. The aim was also to use different time series to calculate the capacity value to see if different time series lead to some differences in the results. The dependence of wind generation on load in Finland was modelled in the thesis. Based on that a simulation model was developed. The simulation model was used to create load, conventional generation and wind generation time series. Finally the time series were used to calculate the capacity value. In addition to simulated time series, also measured time series were used in some cases to calculate the capacity value in Finland. The results show that the capacity value in Finland is about 20 % at the moment, when the simulated time series are used in the calculations. With installed capacity of 2000 MW, the capacity value is 12 %. With measured time series the same numbers are 18 % and 10 %, respectively. Based on the results, the capacity value in Finland is less than in some other European countries. The main reasons for that are lower wind generation during the peak load and higher generation adequacy. It can be concluded that wind generation during the peak load is clearly the most important factor affecting the capacity value of wind power. The results show also that exact value of generation adequacy is not so relevant to know when the generation is very adequate.Description
