Abstract

The paper presents a proposed technique with linearized formula for computing the transmission line power flow in terms of injected power due to any change in power system loading conditions. The formula relates the line power flows to both loads and power generation directly for a transmission network configuration. Being in an integral form, new power flows on the lines can be obtained directly without running a complete load flow programs when the total system generation changes. This formula is a fairly general one as it is suitable for various energy monitoring and control applications such as generation shifts to alleviate the line overloads, the generation redispatch for an incremental change in loading conditions and the on-line load shedding programs as well as the fast contingency analysis.
