基于不确定性分析与电价波动的电—氢—热综合能源系统分析
Analysis of Electric-Hydrogen-thermal Integrated Energy System Based on Uncertainty Analysis and Electricity Tariff Fluctuation
摘要
Abstract
Under the background of the'dual Carbon'goal,the construction of an integrated energy system with electric-Hydrogen-thermal multi-energy flow can not only solve the difficulty of renewable energy grid connection but also promote Carbon reduction and emission in the energy field.For the energy system containing electricity,heat,and gas,the fuel cell and electrolytic cell are taken as the energy hubs to realize the mutual conversion of different kinds of energy,improve the gradient utilization efficiency of energy further,and strengthen the flexibility of grid dis-patching.In this paper,an integrated energy system containing electricity,heat,and gas based on uncertainty analy-sis and electricity price is set up,and the influence of different energy consumption modes and electricity price fluctu-ation on the cost of the integrated energy system is analyzed.Then,the influence mechanism of the uncertainty of re-newable energy on the decision-making process of curtailment of wind and solar energy is studied.The results show that the integrated energy system can realize peak-valley shifting and long-time energy storage by high efficiency.The phenomenon of curtailment of wind and solar energy due to the uncertainty of renewable energy uncertainty can be eliminated by reducing the cost of wind and solar power generation,thereby improving the stability of the integrat-ed energy system.关键词
