In recent years, Energy Management Systems (EMS) have evolved as a means to control power systems from a central location. Interchange brokering is a part of EMS that is fast emerging. It schedules power imports and exports between interconnected utilities to maximize profits for all participating parties. The data required for interchange-brokerage systems is the amount of power available for trading and the system incremental cost. The source of this data can be either from an Economic Dispatch Calculation (EDC) or an Optimal Power Flow (OPF). By industry convention, interchange brokerage systems operate on an hourly basis while EDC and OPF provide instantaneous results. Thus, it is assumed that the system remains in steady-state mode for the hourly duration of the interchange brokering operation. For a complete analysis of a power system, an OPF is desirable because it combines a Power Flow (PF) and an EDC into one package. To enhance the efficiency of EMS, linear programming is used in the solution of OPF and interchange brokerage systems. The OPF problem is decoupled into its active and reactive subproblems.
