A multi-type energy storage multi-level control method, comprising: a fluctuation suppression strategy, an energy/power distribution strategy, and an economic operation strategy. The fluctuation suppression strategy is used to smoothen a microgrid original power curve, so as to obtain a microgrid grid-connected power curve and an energy storage total load curve; an energy storage charge-discharge distribution strategy based on a power-type energy storage charging state is used on the basis of a first-order filtering algorithm, to implement power distribution between energy-type energy storage and power-type energy storage; and an economic operation strategy based on full life cycle costs is used to implement power distribution inside the power-type energy storage (that is, power distribution between supercapacitor and flywheel energy storage), and an economic operation strategy based on per-kilowatt-hour electricity costs is used to implement power distribution inside the energy-type energy storage (that is, power distribution between a lithium battery and a flow battery).
