opf_branch_flow_hess()
- Evaluates Hessian of branch flow constraints.D2H = OPF_BRANCH_FLOW_HESS(X, LAMBDA, OM, YF, YT, IL, MPOPT) Hessian evaluation function for AC branch flow constraints. Inputs: X : optimization vector LAMBDA : column vector of Kuhn-Tucker multipliers on constrained branch flows MPC : MATPOWER case struct YF : admittance matrix for "from" end of constrained branches YT : admittance matrix for "to" end of constrained branches IL : vector of branch indices corresponding to branches with flow limits (all others are assumed to be unconstrained). YF and YT contain only the rows corresponding to IL. MPOPT : MATPOWER options struct Outputs: D2H : Hessian of AC branch flow constraints. Example: d2H = opf_branch_flow_hess(x, lambda, mpc, Yf, Yt, il, mpopt);
