Thanks Carlos. I see. That makes sense. But why not always maximizing the wind power and model it as negative PQ bus?

The idea is to capture the variability of wind, given a forecast, using those plausible wind realizations. In each scenario, the Pmax value of the wind generator varies to indicate the availability of wind for that particular scenario. The optimization then will decide on whether to push the Pg of the wind turbine all the way to that Pmax or somewhere in between if there is a need to curtail some of the wind generation. Carlos.

Another question about the wind power integration, do you model wind power injection as a control variable to be solved after optimization, or you model wind power injection as negative load on PQ bus since wind power can be known by forecasting under each scenario? If the wind power is control variable, how it can be determined since we cannot control weather condition?

I believe that only the very latest versions of intlingprog (of the Optimization Toolbox) are up for the task. If you don’t have the latest version of Matlab (and even if you do), I would strongly recommend using Gurobi or CPLEX (free for academics) if possible. So, I suspect the issue may be that you do not have the latest version of intlinprog. Type mpver to display the versions of all of the MATPOWER related tools installed.

I was trying to run the sample codes in Section 2.3.1 of MOST manual. However it feedback me errors. I've attached it, could you take a look? Much appreciation Wenlei <MOSTerror.PNG>
