Study On Location Of Coal-fired Distribution Hub In Coastal Power Plant

Recent years,with the rapid development of the economy in our country,total electricity use has been growing year by year,therefore power generation groups are under increasing pressure.Although there are many ways of generating electricity,coal-burning electricity generation is still the main power form.The distribution of coal resources of our country shows the characteristics that south has more coal than north,but the situation of demand displays the opposite features.Southeast coastal power generation enterprises purchase the northern coal from long range marine transport to ports and then transit to the power plant.Because of the separate management of the power plant inventory,the large amount of coal storage,the occupation of funds and the high cost of management,thus the power generation group attaches great importance to the coordination of coal supply chain and power plant coal inventory management.This paper mainly studies the location problem of the distribution hub in the coal supply chain of the power generation group.First of all,this paper reviews the coal supply chain theory,inventory theory,distribution hub related theory,site selection theory and domestic and foreign research on supply chain inventory.Based on the previous research,this study analyzes the characteristics of coal-fired transportation,coal-fired purchase and coal-fired stocks in power plants,and summarizes the whole process of coal supply chain from upstream procurement to hub storage distribution then to power plant production.Secondly,according to the diversification of coal demand of the power station,the large amount of safe stock,the high transportation cost and the close distance of the power plant,the centralized storage of the distribution hub and the selection of the port transportation are considered to build the coal transportation hub location model.Moreover,this paper takes a power generation group as an example,based on GIS and MicroCity to sort out the data,and use MicroCity software to call CPLEX in order to accurately solve the model and show the results.Finally,the influence of different conditions on the location results is studied by solving various scheduling cycles.
