Research on Coal Inventory for Power Generation in Electricity Supply Chain

The coal inventory for power generation in electricity supply chain in China,where the coal-fired power generation lies in the most important position,is researched.In allusion to the multiple feedback,time delay and nonlinearity of coal inventory system in power supply chain,based on the principle of system dynamics two models of coal inventory for power generation in power supply chain under two different mechanisms,namely current market pricing system of coral and electricity and coal price and electricity price linkage system,are built,and main factors impacting coal inventory for power generation under the two mechanisms are discussed,and a rational management strategy of coal inventory for power generation is determined for the power supply based on coal-fired power generation.Besides,the measures for coal price and electricity price linkage are suggested to mitigate the contradiction in the supply of coal for power generation.
