Transmission pricing using power flow tracing methodology with consideration N-1 security criterion

Abstract

The transmission usage cost allocation is one of the major issues experienced by the Electric Supply Industries. A technique is proposed which is based on graph theory for the transmission usage cost allocation to generators. The proposed impact factor is used to allocate transmission usage cost to generator based on the contributions to maximum line flows under N -1 contingency condition. For allocating the cost, Line Outage Impact Factor (LOIF) and proposed Maximum Line Outage Impact Factor (MLOIF) is used. For transmission usage cost allocation modified MW-Mile method is used. IEEE 14 bus system is used to explain the feasibility of the proposed methodology. Index Terms--Modified Kirchhoff matrix, power flow tracing, transmission pricing, transmission cost allocation.

Power System Transmission Pricing-A Review

“…In a similar study Kilyeni et al have used the real and the reactive power flow tracing method based on the z bus system matrix for the transmission cost allocation [23]. A recent study conducted by Rathore et al has allocated the transmission usage cost to the generators by proposing technique based on the graph theory based on the contribution to the maximum line flows under n-1 contingency condition [24].…”
