Abstract：The new-type power system requires the power grid to consume a higher proportion of new energy,the current high cost of energy storage restricts its large-scale application.Strengthening the reliability of coal inventory of coal-fired peaking units is the basis for ensuring the secure and stable operation of the new power system at this stage.A system dynamics method is used to establish an optimization model for inventory management of peaking units considering coal futures trading,on the basis of which a simulation experiment is designed according to the coal futures trading rules,and a reasonable replenishment strategy for futures and spot is formulated in parallel.Finally,taking a peaking unit as an example,it is proved that the model can guarantee the coal reliability of the peaking unit and effectively avoid the waste caused by excessive storage of coal by combining the futures spot merger and acquisition.The conclusion of the study can provide optimization strategy and decision-making reference for the coal management of peaking units in coal-fired power plants.
