Abstract
The problem of fossil energy shortage and pollution has become increasingly prominent. In China, government-led electric energy substitution projects are being carried out in nationwide, aiming at the end of energy consumption links, using electricity instead of coal-fired and oil-fired energy consumption, in order to optimize the energy structure and achieve the goal of energy conservation and emission reduction. Aiming at the planning and benefit sharing of electric energy substitution project, this research first designs the planning mechanism of electric energy substitution for productive users, analyses distribution network planning, transformation subsidy and so on, and puts forward three schemes. Secondly, based on the cooperative game theory, the benefit allocation model of electric energy substitution project is established. Finally, we take the flue-cured tobacco project about replacing coal with electricity in three areas of Yunnan province as an example to analyze, optimize the game strategy, and put forward three indicators to measure the benefits of the participants in the project. The pollution reduction situation that can not be converted into economic benefits is counted. The modeling results show that the density of users geographically will directly affect the cost of the distribution network transformation. The coal flue-cured tobacco heat loss and serious pollution, after optimization, power grid enterprises can quickly recover investment.
Highlights
With the excessive consumption of global fossil energy, the problem of energy shortage and environmental pollution is becoming increasingly prominent
C long-term Substitution Assuming that the number of potential users in a certain area is huge, the number of Stubborn-type users accounts for a large proportion of the total number of users, and the cost of distribution network transformation is high, this type of User Clusters (UC) and power grid enterprises (PGE) are more suitable for long-term substitution, and government total subsidies for UC need to be increased by a large margin
UC is the set of decision variables of UC in electric energy substitution project, qUC is the total number of UC, qtk is the number of k-type users who accept substitution in the t-th year, and X3 is the set of substitution users
Summary
With the excessive consumption of global fossil energy, the problem of energy shortage and environmental pollution is becoming increasingly prominent. The UC are classified according to the number of users, VOLUME 8, 2020 the psychological acceptance of electric energy substitution projects and the cost of distribution network transformation. C long-term Substitution Assuming that the number of potential users in a certain area is huge, the number of Stubborn-type users accounts for a large proportion of the total number of users, and the cost of distribution network transformation is high, this type of UC and PGE are more suitable for long-term substitution, and government total subsidies for UC need to be increased by a large margin. Because of the different roles played by UC, PGE and government in the distribution of electric energy substitution benefits among different subjects, and the different goals pursued by the corresponding subjects, the game behavior of the interests of each subject is generated when the project is carried out. By objectively analyzing the benefit contradiction of electric energy substitution for each participant can we effectively coordinate the benefit distribution of each game subject and fully tap the potential of electric energy substitution
