Reactive power considerations in ATC computation

摘要

Reactive power impacts are considered in linear methods for computing Available Transfer Capability (ATC). A new approach that first determines the reactive power flows using the exact circle equation for the transmission line complex flow, and then determines ATC using active power distribution factors is given. The ideas are demonstrated on 3-bus and 7-bus systems, and the results are discussed and compared with those obtained without reactive power considerations, and full nonlinear solutions. The following text includes the text and results from the conference paper: “Reactive Power Considerations in Linear ATC Computation”, presented at the 1999 Hawaii International Conference on System Sciences, Maui, Hawaii, January 5–8, 1999.
