A game theory based method for inter-plant heat integration considering cost allocation

Inter-plant heat integration is an effective way for energy recovery in process industry. Although inter-plant heat integration can significantly reduce energy consumption, it is not widely applied in the multiple stakeholders’ situation due to profit or cost distribution problems. Therefore, this work considers both the technique aspects of heat integration and its business aspects between stakeholders simultaneously. The new proposed methodology consists of three steps. Firstly the optimal matching of heat integration between plants is obtained through mathematical programming. Then the cost distribution is decided through game theory. Finally the cost distribution obtained previous is corrected by an ideal expert model. A case study is used to illustrate the effectiveness of the method in the end of the work.

Modeling of Economic Cost Distribution in Screw Thread

The screw threading produce is a important process course.The economics modeling is established in this paper so this process will be investigated.In this paper modeling of process is analyzed.The Q and cost decreases with the increasing quantity while the same turn as AC>AFC>MC is found.AC and AFC is main factors to affect quantity then MC do.It fits to concept of them well.The cost AC and AFC is higher upon L=4 than L=6 while MC is higher upon L=6 than L=4.Meantime the TC and VC is higher upon L=6 than that upon L=4,is the near parallel line.The TC>VC is turn to affect cost.There is a difference for them.TC and VC is main effective costs to compare with AC,AFC&MC.The TC and VC become bigger upon K=5 than K=7.

Dual Channel Pricing of Large Fresh Chain Stores Considering Distribution Costs under Split Quotation

After large fresh food chain stores have opened online channels,distribution costs are a key factor affecting consumers'online buying behavior,which affects dual-channel pricing.This paper studies the dual-channel pricing strategy of large fresh food chain stores on the premise of dividing the quotation,considering the consumer's acceptance of online channels and the sensitivity to distribution costs.The research found that the optimal pricing of online channels is lower than that of retail channels.The optimal pricing of online channels is positively correlated with the acceptance of online channels,and negatively correlated with the sensitivity of consumer distribution costs.Moreover,after retailers have opened online channels,the market scale has expanded compared with traditional retail channels.Finally,numerical experiments are used to analyze the influence of various influencing factors on retailers'decision-making.

Incremental cost analysis model of distribution network based on economic dispatch of distributed new-energy storage system

With the implementation of China’s carbon-peaking and carbon-neutrality strategy,new energy will achieve leapfrog growth.Due to the good economics of distributed new-energy generation,it can not only save users’own investment,but also help to achieve local consumption of new energy.However,it will also bring about a series of incremental costs to the power grid.This paper first enumerates the concept,development status and scheduling mode of a distributed new-energy storage system.Based on the above,it establishes a new-energy power generation model and an energy storage system charging and discharging model,and proposes a global optimization scheduling model for a distributed new-energy storage system,considering the time-of-use electricity price and taking the lowest total operating cost of the distributed new-energy power generation system as the objective function.Finally,it proposes a distribution network incremental cost analysis model based on the penetration of distributed new energy.The calculation results show that the incremental cost of grid-connected distributed new energy is 1.0849,1.2585 and 1.3473 yuan/kWh,respectively,which indicates that the global dispatching model can optimize the power consumption structure of a distributed power generation system,and has the function of peak shaving and valley filling,but the incremental cost of the distribution network will also increase.
