Research On Loss Allocation Problem In The Electric Power Market

Wheeling will greatly increase the loss of the middle grid which offers channel for thewheeling. How to allocation the loss to those relative grids affects the economic benefit ofeach market member. There are many arguments about the existing loss allocation methodsbecause of their different theory basic and calculating result.In this paper, it introduced some loss allocation methods and their application ininternal and overseas power markets, compared their theory and adaptability to differenttrading models. Considering that the flow tracing method based on graph theory can'tsolve the problem of loop flow, this paper proposed a method based on bus-line incidentmatrix to detect if there is loop flow in the grid and a method combining graph theory withlinear equations to calculate those nodal losses involved in loop flow, an example provedits validity, proposed some thinking about charging power problem in the reactive powertracing process.
