Research on Loss Allocation of Inter-provincial Transmission Lines in Interconnected Power Grid

To the problem of loss allocation of inter-provincial transmission lines in interconnected power grid, this paper put forward the method of proportional allocation of loss power, which was used to analyze the loss of inter-provincial transmission lines in an interconnected power grid. At the same times, this paper analyzed the loss of inter-provincial transmission lines in an interconnected power grid, when generators participated in the loss allocation. And the method of loss allocation was certificated to be fair, reasonable, intuitive and simply. It have significant meaning for grid company to cut down the loss of inter-provincial transmission lines, analyze the composition of transmission cost, and draught the rational transmission pricing.
