A Primal-Dual Interior-Point Method to Solve the Optimal Power Flow Dispatching Problem

摘要: This paper presents a primal-dual path-following interior-point method for the solution of optimal power flow dispatching (OPFD) problem. The underlying idea most algorithms is relatively similar: starting from Fiacco-McCormick barrier function, define central path and loosely follow it to optimum solution. Several methods OPF have been suggested, all which are essentially direct extensions linear programming. Nevertheless, there substantial variations in some crucial details include formulation non-linear problem, associated system, algebraic procedure solve this line search, strategies adjusting centring parameter, estimating higher order correction terms homotopy path, treatment indefiniteness. discusses approaches that were undertaken implementing specific OPFD. A comparison carried out with previous research on OPF. Numerical tests standard IEEE systems realistic network very encouraging show new algorithm converges where other fail.
