Reactive flow equations
WebNov 1, 2016 · Successive linear approximation of the ACOPF model with both active and reactive power flow equations is a representative approach. Recently, a successive LP (SLP) approach for ACOPF was proposed . Using bus voltage and current injections, the OPF problem was modelled using the ‘IV-ACOPF’ formulation, in which the network balancing ...
