With the start of trial operation of direct purchasing electricity for large consumers in China, the method on how to allocate the wheeling charges of large consumers is of vital theoretical and practical significance. An integrated method for allocating the congestion management cost of larger consumers is presented in this paper considering time-of-use (TOU) pricing in congestion period, power supply reliability and the use capacity of the line. Modeling the TOU index, power supply reliability index and use capacity of the line index is proposed. The weights of three indices are determined by interacting between the transmission utility and large consumers based on multilevel models to get comprehensive evaluation indices for all consumers. The integrated indices are used to allocate the cost. Test results show that the method can allocate the congestion cost more reasonable.
