With the increasing need for the energy, the importance of renewable energy sources has also been increasing. In order to include the power produced by the wind into electricity grid in a controlled manner, power prediction has an important role. To produce a reliable wind power forecast, obtaining Wind Power Plants' (WPP) power generation data in real time and constructing the power forecast model with historical production values is a desirable action plan. However, this situation may not be applicable for all WPPs in the country due to difficulties in obtaining such data from WPP in real time. Therefore, there is a need for upscaling algorithm for generating the power forecast of such WPPs and producing a regional power forecast for a given region or the whole country. In this work it is aimed to construct an upscaling wind power forecast model to answer these needs. Many models in the literature propose techniques for the estimation of the entire zone rather than an offline plant. Offline plants are the plants such that their production data is not available in the system. In this work, we propose a method for generating power forecasting for offline plants, and for a region at the same time. The technique is based on firstly power forecasting for offline plants, and then upscaling to region by using forecasts for both online and offline wind power plants. The performance of the method is experimentally evaluated with baseline and previous techniques and it is shown to provide higher accuracy for power prediction.

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...
A new data mining based upscaling approach for regional wind power forecasting

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) powe...
Determination of wind power potential and optimal wind power plant locations in Turkey

Due to increased environmental concerns, utilization of the renewable energy, especially the wind power, gains importance. Like developed countries which have set their renewable energy targets for the long term integration, Turkish government has also set the goal as 20 GW of total wind power installed capacity in 2023. In this thesis, the wind power potential in Turkey is analyzed and different cases are studied to determine optimal locations for wind power plant establishment. In order to determine the w...

Efficient integration of renewable energy sources into the electricity grid has become one of the challenging problems in recent years. This issue is more critical especially for unstable energy sources such as wind. The focus of this work is the performance analysis of several alternative wind forecast combination models in comparison to the current forecast combination module of the wind power monitoring and forecast system of Turkey, developed within the course of the RITM project. These accuracy improve...
