Abstract

The paper presents some initial concepts on including reactive power in linear methods for computing Available Transfer Capability (ATC). It proposes 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. 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.
