Shading effects produced by wind turbine generators on PV plant production

[Vinh Thinh]

Hi all,

 

I have to run a simulation in PVsyst in order to compute the shadowing impact created by the presence of three wind turbine aerogenerators located within the layout design of an agrivoltaic PV plant. 

To do so, I am well aware of the fact that I can import in the PVsyst tool Near Shading 3D scene a .pvc file (from PVcase) of the layout which can include the 3D shadowing items of the 3 wind turbines with the aim to compute in the simulation the impact of the shadows generated by those turbines with respect to the PV plant producibility. In this regard, I would like to know:

- if the software quantifies such shading losses in the loss diagram under the voice Near Shading Losses. If not, please clarify in which voice they are allocated in the loss diagram

-if there is some kind of way to compute the impact of the shadings generated by the wind turbines in a daily/hourly/monthly formats to understand for example through the year in which periods of time (days, hours) the shading effects is more relevant

Please let me know if there is the need of any additional information that could be helpful to provide an answer to my questions.

Thank you in advance.

Losses due to specific objects are not isolated. Shading from turbines will be included in both near shadings and electrical loss in the loss diagram. To isolate the turbines run models with and without them, take the delta of shading losses and you can calculate whatever you need. You will also have energy with this, so you can easily calculate overall energy impact monthly, etc.

Thank you for the reply 🙂

Regarding your answer, I would like to have a better understanding on how to apply your procedure in order to visualize and quantify the shadowing impacts of turbines.

First, I get that I shall generate two simulation variants one with and the other without them and from the two loss diagrams see the corresponding near shadings and electrical losses. In order to calculate those losses in MWh, if I understand correctly, I should multiply the energy production values with the near shading and electrical losses expressed in %. Am I right? 

Secondly, in order to calculate the overall energy impact on different timeframe basis (monthly, daily...) I would like to understand if there is a way in PVsyst to extract the production values with respect to such timeframes. Did you have in mind another way to compute and identify those losses ?

 

Thank you.
