Abstract: Suitable pricing of the electricity price cross subsidy of electricity price is not only a key point for transmission and distribution prices reform, but also important for promoting the development of electricity market reform in China. Considering the transmission and distribution prices reform as well as load characteristics of the electricity consumers, this paper proposes a electricity price cross subsidy calculation model for different kinds of electricity consumers under different voltage classes, and then empirical analysis is performed by taking a north province of China as an example. The results show:(1) residential consumers and agricultural consumers are cross subsidy receivers, of which the residential consumers obtain the most cross subsidy, namely, 92.84% of the whole package; (2) large industrial consumers and general commercial consumers are cross subsidy suppliers, of which the large industrial consumers provide the most cross subsidy, namely, 51.59%; (3) the lower the voltage level, the more the electricity price cross subsidy of residential consumers and agricultural consumers can obtain.
