Together with the increasing need for energy, the importance of renewable energy sources has been increasing day by day. Although wind is one of the most important alternative energy sources due to its high potential, it is not a stable source since it depends on the weather conditions. So, in order to include the power produced by the wind into electricity grid with planned manner, it must be predicted accurately beforehand. To produce a reliable wind power forecast, getting a Wind Power Plant’s (WPP) power data in real time and constructing the model with past production values is an expected and optimal situation. However, this situation cannot be applicable for all WPPs in the country due to the difficulties on getting the power data of WPP in real time. Hence there is a need for accurate upscaling algorithm for generating the power forecast of such WPPs and producing a regional power forecast for a given region. These forecasts are especially so crucial for the management and planning of the electricity grid. It is very important that the system operators who manage the energy flow in the country use their energy resources correctly by using these power forecasts day in advance. In this thesis, six different statistical based models are developed to solve the regional wind power estimation problem and the results obtained are compared with some well known statistical based machine learning models in the literature such as ANN and SVM. The most important contribution of the proposed method is that it produces regional power forecasts while also generating power estimates for wind power plants in the system for which we do not have their historical power data. Another advantage of the method is that the wind potential of a candidate point where a wind farm is planned to be established can be determined by this method. In this thesis, this feature of the model is tested for 16 different candidate points from four different cities of country. In addition, regional forecasts results are tested for 9 different load distribution regions and performance results of the models are analyzed.

As the result of increasing population and growing technological activities, nonrenewable energy sources, which are the main energy providers, are diminishing day by day. Due to this factor, efforts on efficient utilization of renewable energy sources have increased all over the world. Wind is one of the most significant alternative energy resources. However, in comparison with other renewable energy sources, it is so variable that there is a need for estimating and planning of wind power generation. In thi...

As a result of rapid depletion of non-renewable energy resources, the importance of the e efficient utilization of renewable energy sources has increased all over the world and in our country in recent years. Wind has an important role in renewable energy sources with its high potential. However, compared to other renewable energy sources, wind has a spatial and temporal discontinuity characteristic so there is a need for estimating and planning of wind power generation. Wind Power Plants (WPPs) inform thei...

Fossil fuels has preserved their importance in gradually increasing production and consumption of both energy and electricity of the world. Asia, especially China and India, has arisen new actors of the sector. Energy and electricity consumption of Turkey has also increased in parallel with her economic development, but due to her limited resources, she has become more and more energy dependent in order to meet her growing demand. Although hard coal is only found around Zonguldak region, with its abundant a...

It is well-known that even though fossil fuels are the main energy resource in Turkey, use of sustainable energy resources such as wind and solar energy has been increasing in the past years and expected to continue on this trend in the next years to come. The suitable land for land-based wind turbines and photovoltaic (PV) systems could also be convenient for various other purposes, such as agriculture. This study aims to investigate the suitable sites for a combined floating wind and solar systems in the ...
