How can I simulate varying quantities? Can I store the results?
You can simulate varying quantities (and store the results) by using the Time Step Simulation (TSS) tool. TSS allows you to specify operating conditions and obtain power flow solutions for a set of points in time. It provides the tools needed to analyze the operation of a power system hour by hour. TSS is included in the base Simulator package. OPF and SCOPF licensees can also solve hourly optimized scenarios in which the TSS tool obtains the optimized generation dispatch for each hour of the analysis horizon. 
See the Time Step Simulation chapter in the help files included with your software for more information on how to use the TSS tool and store the simulation results.
