Research on transmission and distribution electricity price calculation model for carbon cost allocation of power grid equipment under the dual carbon target
Accelerating carbon footprint management is an important part of achieving the "dual carbon" target, and it is of great significance for promoting green production. How to effectively allocate carbon costs has also become one of the focuses of attention. This paper conducts a carbon footprint analysis of power grid equipment based on the whole life cycle theory, focusing on the operation and maintenance and retirement and scrapping stages, and constructs a carbon cost calculation model for equipment. By referring to the pricing mechanism of transmission and distribution electricity prices, the cross-subsidies of carbon costs are analyzed, and the allocation scale of carbon costs of power grid equipment among industrial and commercial users is calculated based on the price difference method. A carbon cost allocation method based on balance coefficient between different industrial and commercial users is proposed. The calculation results show that without considering cross-subsidies, 10 kV users have the highest proportion of carbon cost allocation, accounting for 41.67%. The introduction of the balance coefficient helps government departments to effectively allocate carbon costs, thus verifying the scientific and practicality of the proposed transmission and distribution electricity price calculation method.
