Beschreibung
Zusammenfassung:	The invention provides a wind-hydrogen system optimization scheduling method considering thermodynamic characteristics and state transition, and the method comprises the steps: building a wind power-hydrogen production-hydrogen storage system, and building mathematical models for a fan, an electrolytic cell, an alkali liquor circulation system, a compressor and a hydrogen storage tank respectively; in particular, a tangent plane equation is used for linearly representing the relationship among the power, current and temperature of the electrolytic cell; in order to enable scheduling calculation to be accurate enough, the system introduces a production state, a standby state and a shutdown state; establishing a mixed integer linear optimization model including hydrogen and electricity selling income, investment cost and operation and maintenance cost by taking the maximum system income as a target according to wind power output and electric load and considering the running state of an electrolytic bath, power
