Dear all,
I have radiation parameters GHI, DNI, DIF and COSZEN. Now, I need to calculate solar power using above parameters. Can anyone help me regarding this or share any literature related to this.
Regards,

You can develop a Neural network based prediction model which can be used to predict solar power based on the parameters you have. You will be using GHI, DNI, DIF and COSZEN as your input parameters and then your solar power will be your output from the prediction model.

GHI is solar irradiation received in horizontal surfaces. You have to be specific about orientation angle and area of the surfaces that you want to determine. The above mentioned book "Solar Engineering of Thermal Processes" will help you a lot.

Dear Malleswararao,
If you could explain what do you mean by calculation of the solar power, you could get more specific answers. If you mean the solar irradiance, I see you already have these information and you may need some principle equations (that could be available in one of the solar energy books/articlas as suggested by Mr Nabil above) to estimate the irradiance on an inclined surface or other parameters. If you your question is how to generate power (mechanical or electricity), then there are different means to do so which depends also on how high the solar irradiance is it?

Dear Malleswararao,
If you have Matlab, you can use the PVLib toolbox from Sandia National Labs. With this toolbox you can easily compute PV power output from GHI (and also from DNI and other data if you have them). The toolbox has modules parameters and inverter libraries as well.

There are 2 steps involved:
1. Calculate the incident irradiance. This is DNI (that you have) for CSP/CPV systems, or GTI for flat-plate (PV or thermal) systems. In your case, GTI would have to be modeled from GHI and DNI using one of many possible transposition models. See e.g. https://www.researchgate.net/publication/236314649_From_global_horizontal_to_global_tilted_irradiance_How_accurate_are_solar_energy_engineering_predictions_in_practice?ev=srch_pub
2. Calculate the power produced by the system. This can be done using a variety of tools. Some are free from NREL (SAM, PVWatts) or other sources (RETscreen); others are commercial (e.g. Archelios, PV-SOL, PVSYST).
