Forecasting models of solar powerplants and wind farms production based on numerical weather prediction models
 Farda, Aleš ; Štěpánek, Petr ; Zahradníček, Pavel ; Rajdl, Kamil ; Meitner, Jan
Performance and potential of daily based forecasts of renewable energy sources power production have been investigated for the Czech Republic. The role of individual numerical weather prediction model errors has been researched and ensemble based technique has been studied as the mean to obtain more precise and reliable results providing a benefit for end users.\n\n

Predictability of wind famrs operated by Amper-Market company
 Farda, Aleš ; Rajdl, Kamil ; Štěpánek, Petr
This report contains an analysis of the electric energy production of wind power plants of the company Amper Market a.s. from the point of view of its predictability, with the main objective of determining the potential accuracy of hourly predictions of the power production. To calculate the analyzed predictions a regression forecasting model utilizing wind speed and direction in two height levels is used. The necessary values of these meteorological variables are obtained from three numerical weather prediction models – Aladin, EPS Aladin and IFS. The accuracy of the energy production predictions is optimized regarding the choice of suitable geographical points for obtaining outputs of the numerical models, the combine utilization of the models and individual setting of the regression model for the single power plants. The analysis was performed based on data from the period January 2013 to April 2014.

Porovnání výnosnosti generických větrných projektů ve střední a východní Evropě
 Dvořák, Petr ; Neumaierová, Inka (advisor) ; Vrbský, Petr (referee)
The aim of this diploma thesis is to suggest the best locality in the CEE region for a prospective investment in wind farms for an undisclosed Czech company. This goal is to be achieved by comparison of generic projects that have the same technical specification, capital expenditures and operating expenses. These projects are investigated from different perspectives including wind conditions, financing terms, technology constraints and mainly the legal aspects of each respective country -- namely the regulatory environment for wind power-offtake either feed-in tariff or green certificate support schemes. The NPV of FCF and IRR (MIRR) are to be used for evaluation of these projects. Sensitivity analysis for key drivers will complement prior assumptions.
