Abstract :
This paper presents the huge but useful formulation of expected security cost optimal power flow (ESC-OPF). Corrector equation, which has special structure, of interior-point method (IPM) for ESC-OPF has been given. A novel parallel IPM based on multiple centrality weighted correctors (MCWC) has been proposed to solve the formulation of this ESC-OPF model. In our novel algorithm, with the cooperation of MCWC and parallel solver for corrector equation, iterative times can be reduced and CPU time can be shut down because of the good speedup.
