Dear Ray, I am planning to add them as a simple MW injection with a negative value and then i want to control them.
For example on the bus that a renewable generator is connected i am saving the results for the power flow and then i am setting some rules to control the renewable generator i.e if the power flow its more than 100 i want to curtail the generator with the specific value which the system will run in a safe operation i already achieved this part but right now i am trying to include more renewable generators and curtail them one by one which i define as a priority on my case format.

As a simple MW injection (e.g. equivalent to a negative value in the PD column of the bus matrix)? As a zero-cost generator with a PMAX value that depends on the current wind conditions (why not simply add them to the gen matrix with a zero cost in gencost?)?

The only thing i don’t know how to develop is the following: For example in the following case format i define two renewable generators on bus 2 and 3. What i want to do is write a code which will identify but its self on which bus the renewable generators will be connected. i.e. if i will create a different case format with more busses lets say 10 bus system i want the same process to be followed as the above and when i will change the number on which bus the renewable generators are connected for example at bus 6 and 10 i want to follow the same process as i mentioned. mpc.renwgen = [ 10 20 1 1 6 10 1 1 ]; Thanks in advance.

And, of course, you are free to specify the data where you like. If you want to specify it as a renwgen field in the MATPOWER case struct, that’s fine. If you want to specify it in a separate file or data structure that is fine as well. Since you are writing the code to take that data and do something with it to modify model, you simply need to have that code be consistent in where it looks for the data. I hope that answers your question.
