[0010] 1 Calculate the long-term marginal cost value of the transmission and distribution network

[0011] The present value NPV (ΔI m ) can be expressed as follows:

[0012]

[0013]

[0014]

[0015] In the formula: and Respectively represent the present value of the incremental investment of transformers and lines with a voltage level of m; and respectively represent the incremental investment of transformers and lines with voltage class m in year t; T represents the number of years in a regulatory cycle; i represents the basic discount rate.

[0016] Calculate the long-term marginal cost value NPV(C m ), which can be expressed as follows:

[0017]

[0018] Where: ΔL t,m Indicates the load increment of the transmission and distribution network whose voltage level is m in the t-th year; α indicates the return on investment of the transmission and distribution network; and other expenses.

Abstract

The invention provides a method for automatically calculating electricity price cross subsidy. The method comprises the following steps: calculating a long-term marginal cost value of a power transmission and distribution network; calculating a power transmission and distribution network cost value borne by each voltage level user; calculating theoretical power transmission and distribution valuesof various types of users; calculating and checking the total amount value of various types of cross subsidies; and calculating the cross subsidy value of the power distribution network of each voltage level. According to the method, the specific cross subsidy amount of the industrial and commercial users to the resident users and the agricultural users can be calculated, and the total cross subsidy amount is reasonably shared among the industrial and commercial users of various voltage levels.

Description

technical field [0001] The invention belongs to the technical field of power transmission and distribution. Background technique [0002] The current power transmission and distribution price structure in my country is contrary to the basic principles of economics. Taking users as an example, residential and agricultural users are at lower voltage levels, the supply chain is longer, and the power load rate is lower and concentrated in peak hours; industrial and commercial users The voltage level is higher, the line loss rate is lower, and the power load rate is higher. According to the principle of marginal cost in economics, the transmission and distribution price of industrial and commercial users should be lower than that of residential users and agricultural users. However, due to the cross-subsidy of transmission and distribution prices among users, the transmission and distribution price of industrial and commercial users in the actual transmission and distribution pric...
