Time Step Simulation<br />

The Time Step Simulation tool allows you to specify operating conditions and obtain power flow<br />

solutions for a set of points in time. It provides the tools needed to analyze the operation of a power<br />

system hour by hour or by intervals down to one second.<br />

Time Step Simulation is available in the base <strong>Simulator</strong> package. If you own <strong>Simulator</strong>, you can start<br />

taking advantage of this valuable tool right away. In addition, if you own <strong>Simulator</strong> OPF or SCOPF<br />

licenses, you can solve OPF and SCOPF scenarios on a time point to time point basis and use the tool<br />

to evaluate the behavior of prices and operating constraints. The tool will obtain the optimized<br />

generation dispatch for each time point of the analysis horizon.<br />

In order to access the Time Step Simulation, go to the Tools ribbon tab, and choose Time Step<br />

Simulation from the Run Mode ribbon group. This is only available in Run mode. The following topics<br />

describe key components of the time step simulation tool:<br />
