1.5.2 Power Flow (Online/Operator)

Оглавление

PF calculates the state of the electric power system in the form of flows, voltages, and angles based on load, generation, net interchange, and facility status data. PF determines system state. PF are available in both online and offline versions. Online load flow programs are a standard part of all energy management system specification [28].

Online PF is widely used to assess system conditions or perform look‐ahead analysis. It is also used in “n − 1” CA and to identify potential future voltage collapse or reliability problems.

Real‐time reliability tools can only provide results that accurately represent current and potential reliability problems if these tools have real‐time PF and voltage values and status data for other elements included in their models. The accuracy of the information that real‐time reliability tools provide depends on the accuracy of the data supplied to the tools.
