Dear Thomas, If you are only interested in finding the maximum transfer limit, you can use the OPF-based code "maxloadlim" that you can find in the "extras" folder in the latest Matpower version (6.0b1). This OPF-based code allows you to consider the reactive power limits when finding the maximum transfer limit. By default, the bus voltage limits are relaxed, but should you wish to keep them you can comment out the corresponding two lines of code. This OPF-based code does not provide the P-V curves, however.

Just to be sure: So in the end it doesn't matter how big the Sxfr is. Important is only the relation between the different rows of the vector?

Gesendet: Donnerstag, 9. Juni 2016 16:54 An: MATPOWER discussion forum <matpowe...@list.cornell.edu<mailto:matpowe...@list.cornell.edu>> Betreff: Re: CPF - Functionality 1. Yes. 2. CPF with generator active and reactive power limits should be hopefully available in the upcoming version of MATPOWER. Checking for min. or max. bus voltages is not available in CPF. With some modifications in the CPF code, you should be able to check voltages. We were working on user-defined callbacks for CPF to enforce limits, check voltages, or any other user-defined operation. But, we decided to not add in the MatPower code base for now. Hopefully, we can have that feature available in the future.

If I get it correctly, it can be used the following way: You have to import a basescenario and a targetscenario. Then the tool calculates the difference (Sxfr) between the base-power and target-power at every bus. Based on these datas the actual cpf starts and determines the maximum value for lambda, whereby the maximum transmitted power equals lambda*Sxfr. Is this correct? 2. Is there any way to limit the maximum or minimum voltage per bus or to limit the reactive power generation per generator? Thank you very much Thomas
