New generation distribution factors for active and reactive powers transmission costing

In the paper, a new method of the generation distribution factors appropriate for transmission service pricing is presented. The new method is based on power flow directions and can be utilized for both, active and reactive powers. The method is exact, simple and easy since it does not involve operations on system matrices. The factors obtained by the new method are named nodal generation distribution factors (NGDF-s). The results show that the method can be successfully applied for pricing of the transmission service based on the MW-MILE methodology.
