| In recent years,coal electricity has obvious advantages in the aspects of safety,economy and stability.As people gradually realize the importance of the environment and the effect of starting the long-term target of the environment is gradually passing through various forms of policy,cleaning is internalized in the core of the power system.At the same time,the global warming caused by the uncontrolled emissions of greenhouse gases,such as carbon dioxide,has aroused the general concern of governments and the public.In china,the control targets for carbon emissions are mentioned in the "national independent contribution" and "13th FiveYear" control Plan of greenhouse gas emissions.Under this background,it is very important to optimize the development of coal under the carbon emission policies and guide the win-win of economic and environmental benefits for the coal enterprises.At present,the research on the optimization model of coal supply chain network is still relatively less.It is urgent to construct the optimization model of coal supply chain network under different carbon emission policies and corresponding solution technology.This paper takes the coal supply chain network as the research object,combines with the carbon emission policies.this paper firstly extracts the influence factors of the low carbonization of the coal supply chain,including the supply chain energy effect,the green energy use level,the low carbon production cost,the low carbon green technology,regulatory constraints,policy incentive guidance,etc.And this paper constructs the interpretation structure model of these 12 factors,the most direct factors affecting the low carbonization construction of the coal supply chain are the supply chain energy effect,the green energy use level,the low carbon production cost and the low carbon green technology,and the four factors influence each other.Therefore,the objective of the optimization model is to select the lowest carbon cost of coal.Secondly,combining the constraints analysis of different carbon emission policies for emission cap,carbon tax,carbon trade,carbon offset and the carbon emission and cost analysis involved in the process of coal supply chain,the optimization model of the coal supply chain network under different carbon emission policies is established respectively.Thirdly,for the optimization model established in this paper,the model is solved by choosing the salp swarm algorithm with fewer parameters,simple calculation and fast global optimization.At the same time,the improved salp swarm algorithm is proposed in combination with the idea of differential evolution because of the problem that the algorithm itself is not fully utilized for the population information,which causes the algorithm to fall into local extremum and decrease the convergence precision.Finally,based on the empirical analysis of the X group company,and this paper analyses the parameters of the four carbon emission policies.It is concluded that the carbon trade policy is more obvious than the other three carbon emission policies in encouraging and guiding the coal enterprises to reduce carbon emissions. |
