Resumen de: CN121440605A
The invention relates to a rural photovoltaic and hydrogen energy storage cooperative operation optimization method considering source load uncertainty, and belongs to the technical field of energy system optimization. According to the invention, a rural unit and a hydrogen energy storage system are reasonably and physically connected through an electricity-hydrogen coupling facility (an electrolytic cell and a hydrogen fuel cell) to form a rural photovoltaic and hydrogen storage combined system so as to give full play to complementary advantages and synergistic effects. However, the formation of the system means that besides the source side photovoltaic random output, the interference of load side uncertainty such as electrical load on operation is at least increased. Therefore, it is necessary to explore a scientific optimization method for operation scheduling of the rural photovoltaic and hydrogen storage combined system so as to support economic, low-carbon and stable operation and renewable energy consumption of the rural photovoltaic and hydrogen storage combined system under source and load double-side uncertainty interference, and reasonable implementation of the potential benefits is guaranteed.
