Multi-purpose optimum power flow model for planning, operation and control studies

Abstract

This paper presents a developed multi-purpose optimum power flow model, intended for solving different power system planning, operation and control problems. In that respect, expansion planning of reactive power sources, reliability analysis, economic dispatching, active power loss minimization, rescheduling of reactive power and minimization of control variable deviations can be carried out. Much attention is given to the problem initialization in which different auxiliary modules are used in order to obtain a 'good' starting point. Detailed consideration of the voltage/reactive power subproblem resulted in 'accurate' modeling of power system components. The optimum power flow model is solved by applying the Newton method.
