A method for operation scheduling and capacity configuration of a wind-solar-hydrogen storage system in high-altitude areas

Abstract

This invention discloses a method for operation scheduling and capacity configuration of a wind-solar-hydrogen-storage system in high-altitude areas. The method includes: analyzing the environmental characteristics of high-altitude areas to establish several mathematical models of the wind-solar-hydrogen-storage system, including mathematical models of wind turbines, photovoltaic arrays, hydrogen storage devices, batteries, and a lifespan degradation model; designing an electro-hydrogen composite energy storage scheduling strategy based on the characteristics and lifespan degradation trends of electrical and hydrogen energy storage; and constructing a two-layer optimization model: an upper-layer optimization model that optimizes system capacity with the goal of minimizing the total lifespan cost, and a lower-layer optimization model that optimizes system output with the goal of minimizing load failure rate and excess energy rate, and solving the two-layer optimization model. This invention improves the system's adaptability and operational stability in extreme environments, reduces equipment lifespan loss and system operating costs, and enhances system economy and power supply reliability.
