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 […]
