DearGrzegorz Dudek ,

for wind turbine there is two strategy, firstly if you want to predict wind speed you need wind speed data set and the appertained data e.g. temprature, presure and other related data according to your model.in this case you can use the realistic data which is available for many location e.g  wind speed data collected by Dr. Gary Johnson  from a location in the state of Kansas for ten years and is available on "Electrical and Computer Engineering of Kansas State University, Dr. Gary Johnson’s renewable energy and Tesla coil page. [Online]. Available:http://eece.ksu.edu/~gjohnson/". another case is to predict wind power directly. in this case in addition to the previous data you need wind power outputs. in such a situation you can use the data of wind farm according to your location. e.g historical data of Sotavento wind farm in spain is availible on "http://www.sotaventogalicia.com/en/real-time-data/historical" . 

A good data set for PV may be found in: 

http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6925171&tag=1

These data are publicly available. In the conference paper there is an e-mail address that you should use to request permission to access the ftp. 

I hope that it may be of help! 

Thank you Nikolaos,

I have no access to this library. Could you send me this email, please?

try

http://www.sauran.net 

It is free and contains data for several areas within South Africa. It will be updated to include more and also other regions.

The data is live.

Hello  Grzegorz Dudek,

Surely you will find things here :

Good luck

A good data is found in NASA site in the following link:

https://eosweb.larc.nasa.gov/cgi-bin/sse/daily.cgi

Thank you all very much for help. 

Could you indicate the data sources for wind power generation and corresponding weather data?

This website is used in USA, National Solar Radiation Data Base

http://rredc.nrel.gov/solar/old_data/nsrdb/1991-2005/tmy3/

choose: The Data

Individual Station Files

In alphabetical order by state and city.

It has the data in Excel files, you might find it hard to understand the information in the Excel sheets, but there is a manual also on the website that explains how to navigate through the website and understand the data in the sheets, one more thing you will find classes I, II and III, that represents the quality of the data, also explained in the manual

Good luck

This may be helpfull

Meteonorm software can be used for the same.

Which region are you looking at? Because the data you asked for are location specific

Dear Abubakar,

I need data for tests the forecasting models I am constructing, so the region is not important.

DearGrzegorz Dudek ,

You can used PVsys 

Ok for power generation solar  you could use HOMER, to import  irradiance data for any region, then define a value for the unit PV (kWp), after running HOMER, you could get a complete set of 8760 hourly PV generation values based on the irradiance earlier defined, you could then export that data to a text file externally. For the wind, I don't know the granularity you need (hourly 24hours, complete year?), I have some normalized power generation values.

Yes I agrre with Abubakar Sani Hassan ·

Abubakar and Mostafa, thank you for sources and links.

I want to forecast wind or solar power based on the forecast of weather data. So I would like to get time series of power generation and corresponding forecasts of weather conditions (wind speed and direction, solar radiation, cloud cover). Is such data  available?

DearGrzegorz Dudek ,

I didn't work on PV plant output forecast. but for the wind power prediction, historical data such as temprature, pressure, and wind direction is available in aforementioned link. As i said for wind power prediction you can predict wind power directly or you can predict wind speed firstly and then transform it to wind power by using the power curve of specific wind turbine. it should be noted that forecasts of weather conditions is not avalaibale in these two link. I can refre you two a paper which addresses two wind power plant which you can find forecasted data of weather conditions. 

"Wind Power Prediction by a New Forecast Engine Composed of Modfied Hybrid Neural Network and Enhanced Particle Swarm Optimization

Nima Amjady, Senior Member, IEEE, Farshid Keynia, Member, IEEE, andHamidreza Zareipour, Senior Member, IEEE"

Meteonorm software is always a good tool. The demo version can only provide monthly mean values for both radiation and wind speed data. However, the full software presents data on a hourly basis

for getting wind speed and wind direction data, you must go to "Renewable Energies Organization" in your country,

for forecasting of  wind direction you can use this link:

http://www.srh.noaa.gov/epz/?n=cwopepz

If you want wind speed data for Iran's cities, i put this example link for Khaf city,

the data is for 2007-2009 in this city for every 10 minutes,

you can put the data in MATLAB or other software for analyzing:

See the data from the Global Energy Forecasting Competition 2014:

Thank you Mohamed. I know these data. 

Dear Grzegorz,

Vortex is a website from which you can obtain wind resource data from any region worldwide:

http://www.vortexfdc.com/

For research purposes, they provide data (wind intensity, etc.) for free with a resolution (I think) down to 1 km, or at least they used to do that some years ago when I asked them for data.

Hope this is useful

http://www.vortexfdc.com/

Its really a great resource for getting the wind data

When conducting PV power prediction, whether the meteorological data monitored by the ground weather station or the meteorological data obtained from the weather forecast should be used.

Hi Mohamed Abuella

I have went to the links you suggested above. However, i can't find any data.

Hi Qin Chin

When you join and login to the forum just go to the data tab and you will find csv files over there. Without login you just see the three general tabs, as Home, Leaderboard and Forum, but once you logged in you will see the data tab as well.
