Abstract

Abstract: The problem of cross-subsidy of electricity price in China is very serious, which is unreasonable in both economic efficiency and fairness. By analyzing the current electricity price policy, it is found that the tiered pricing for electricity can solve the cross-subsidy problem, but the effect of current scheme is not obvious, and it needs to be adjusted. What's more, due to the difference in the demand response degree of users of different grades, there are many schemes to solve the cross-subsidy problem by adjusting the tiered pricing for electricity. And there is a solution to maximize social welfare. The aim of this paper is to maximize social welfare, adjust the price of electricity for each file user, and at the same time introduce the Lagrange function to design an optimal electricity price plan for solving cross-subsidy problems and obtaining the corresponding electricity price ratio for each file. The results show that social welfare has a maximum value when the ratio of the block tariff is 1:1.62:2.41. At this time, the ladder price scheme is the optimal one among many schemes, and the social welfare increased by about 70.2 billion yuan for the whole year. The fairness and affordability among users on the basis of solving cross-subsidy issues are considered in this solution. It has important reference value for current electricity price reform.

Key words: cross-subsidy, block tariff, demand response, social welfare maximization
