PowerWorld gives you the ability to specify operating conditions and obtain power flow solutions for a set of points in time.  Our Time Step Simulation tool (included in both the base Simulator package and in PowerWorld Retriever) provides the tools necessary to analyze the operation of a power system hour by hour.

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.
