摘要：

The current electricity-hydrogen integrated energy system models have the problem of inaccurate models of hydrogen production and hydrogen storage devices,which affects the security of system operation and scheduling. Considering the temperature-pressure dynamic characteristic of hydrogen in the high-pressure hydrogen storage tank,an optimal scheduling model of hydrogen-electricity integrated port energy system is built. The excess electric energy of wind and solar power generation is stored by the electrolytic water hydrogen production technology,on this basis,the load demand of electricity and hydrogen is coordinated,which effectively improves the utilization rate of renewable energy and ensures the safe and stable opera- tion of the system. The piecewise linearization of the high-order temperature-pressure nonlinearity model of high-pressure gas tank is carried out,which greatly improves the solving efficiency while guarantees high precision. The proposed method is verified by a typical integrated port energy system example. © 2023 Electric Power Automation Equipment Press. All rights reserved.
