A New Generalized Transmission Pricing Method Based on Maximum Social Surplus

With the deepening of power market reform and the acceleration of new power system construction, power resources will be optimally allocated on a larger scale. The existing transmission pricing methods are difficult to adapt to the new power system, and there is a problem that transmission costs cannot be allocated reasonably and fairly. Based on this, this paper proposes a new generalized transmission pricing method based on the maximum social surplus, which comprehensively considers the generation cost, transmission cost, and power consumption benefit in the source flow analysis. Using the MW-mile method with the best social surplus to calculate the transmission price can realize the fair sharing of transmission costs among transmission users, can reflect the usage of the power network by transmission users, and provide economic signals for power generators, power grids and load planning.
