PowerWorld Simulator, General Demo
This video highlights key features of PowerWorld Simulator and its most commonly used add-ons. Demonstrated features include: one-line diagrams, including flow arrows, animation, and color contouring sensitivity analysis, including power transfer distribution factors (PTDF) and shift factors contingency analysis available transfer capability (ATC) static voltage stability limits (PV Curve) and reactive power margin (QV Curve) […]

Power Transfer Limit Exceeded by OPF
The Optimal Power Flow (OPF) solution involves iteration between a linear program (LP) to adjust controls (usually generation) and a non-linear power flow. If an AC OPF is performed over a very large Area (or Super Area), the LP may attempt to dispatch generators in a manner that exceeds voltage stability margins (PV) or maximum […]

Assigning Costs to Control Adjustments in OPF
Download the example files. Simulator’s Optimal Power Flow (OPF) has 2 options for objective functions: Minimum Cost or Minimum Control Change. Generally Minimum Cost is used where generator bids or costs and load benefits are known. Minimum Control Change is used where it is desirable to relieve transmission overloads with minimum deviation from the present […]

Optimal Power Flow with Load Dispatch
Download the example files. These examples show how Simulator’s Optimal Power Flow (OPF) may be used with dispatchable loads to relive transmission overloading. First, the OPF may be used with the minimum control change objective function. Here, the “cost” of changing a control (generator or load output) is the same for each MW of change […]
