Hi,

Thanks for coming to see my question. I updated my question. sorry for the ambiguity.

I am doing dynamic simulations with wind power penetration. I tried to mimic the stochastic behaviour of wind power plants, so I need to set different output scenarios in tons of cases for a wind farm with fixed capacity (i.e., a 100 MW wind power plant may not always produce the rated power since the wind velocity is stochastic, for example, when the wind is weak, the 100MW-rated wind farm might only generate 20 MW, and increases with the wind velocity.....)

I not sure how to simulate this behavior of wind power in pss/e, because it seems that the wind power model in pss/e is designed for simulating the wind farm working at around 100% of its rated power?

Thank you for your help.

Gary

Hi,

Thanks for coming to see my question.

I am doing dynamic simulations in a case with high wind power penetration. I tried to mimic the stochastic behaviour of wind power plants, i.e., for example, a wind power plant whose capacity is 100 MW may not always produce the rated power since the wind velocity is changing from time to time. Unfortunately, I don't know how to do it in pss/e.

Can you please let me know is there any method to do it in pss/e?

Any help would be appreciated.

cheers, Gary

can you please provide me .sav and .dyr file of any system with renewable integration.

Hi gajendra, you can find it by searching the question "Renewable Plant Modeling - Solar PV - Wind", which is provided by jconto, from which you can learn how to model the renewable plants; and you can replace more conventional generators by wind power to increase the penetration.

EDIT: Are you interested in studying the dynamic behavior of the wind power plants under various output scenarios, or is the wind power just something that allows you to have varied power flows during the dynamic simulation? If the latter, then it might be just easier to model it as a negative load, since it's much easier to control. If not, we'll try to figure something out.

EDIT2: If the goal of your study is to see how changing the operation point of a WPP during the fault would affect the outcome then yes, setting it during power flow would be what I'd do. I wasn't sure if this is what you need or do you need to study how changing the setpoints mid-simulation affects the outcome.

Hi SqFKYo, thank you for that. But I think there might be a difference between the two questions; I didn't find the way to change the govern reference of wind power plant.

Hi SqFKYo, thank you for your patiently reply, yes I want to do the former. In addition, to study the dynamic behaviour of wind power plants in different output scenarios in pss/e, , is this reasonable to set a 100MW-rated wind power plants in different output scenarios before apply a fault?
