When the solution obtained from SDP relaxation of AC OPF is a rankpositive semidefinite (PSD) matrix, this solution is exact to the original problem. Research efforts have been devoted to find a rankPSD matrix. In this paper, a nonlinear programming formulation with the PSD matrix as the ...

Also in the complex case, a positive definite matrix is full-rank (the proof above remains virtually unchanged). Moreover, since is Hermitian, it is normal and its eigenvalues are real. We still have that is positive semi-definite (definite) if and only if its eigenvalues are positive (...
