New energy consumption-oriented hydrogen-electricity hybrid energy storage two-stage collaborative planning method

The invention discloses a hydrogen-electricity hybrid energy storage two-stage collaborative planning method for new energy consumption, and the method comprises the steps: firstly determining a plurality of typical day scenes to represent the annual new energy output condition, and formulating an assessment mechanism; then establishing a cross-scene operation model of the hydrogen energy storage system and an operation model of the electrochemical energy storage system; hydrogen is produced and stored through the energy-abundance-season electrolytic cell by means of abandoned electricity, hydrogen is consumed by the dry-energy-season fuel cell to generate electricity, and large-scale energy is transferred between the energy-abundance-season and the dry-energy-season; long-term cross-scene operation and intraday short-term operation of the hydrogen energy storage system are coupled together through intraday electrochemical energy storage and collaborative optimization operation of an alkaline electrolytic cel
