摘要
随着双碳战略深入实施,以新能源为主体的新型电力系统建设加速,新能源发电占比不断提高,其随机性、间歇性、波动性等特点给电力系统长周期电力电量平衡问题带来重大挑战。针对上述问题,介绍了氢能优势和发展现状,氢能作为一种大规模、长时间尺度的储能技术,有助于破解新型电力系统长周期电力电量平衡问题;着重阐述了电氢融合技术,概述了长周期电力电量平衡问题及解决方法;提出了一种适用于内蒙古电网解决长周期电力电量平衡问题的技术构想——新能源制氢+氢气燃机+可中断负荷,分析了该技术构想在经济可行性、资源再利用、安全支撑、跨能源存储及发展前景等方面具有的优势,以及面临的成本高、安全性差、大容量储运能力不足等亟需解决的问题,对未来电氢融合发展提出建议并作出展望。
With the in⁃depth implementation of the dual⁃carbon strategy,the construction of new power systems mainly based on new energy has accelerated.The proportion of new energy generation has been increasing.The characteristics of randomness,intermittent and fluctuation have posed significant challenge to the long⁃term electric power and energy balance problems of the power system.In response to the above issues,the advantages and current development status of hydrogen energy are introduced.As a large⁃scale and long time⁃scale energy storage technology,hydrogen energy can help solve the long⁃term electric power and energy balance problem of the new power system.This paper highlights on the electric⁃hydrogen fusion technology,summarizes the balance problem and solution of long⁃term electric power and energy,and proposes a technological concept applicable to the Inner Mongolia Power Grid for solving the long⁃term electric power and energy balance problem of new energy hydrogen production,hydrogen gas turbine and interruptible load.The advantages of the technological concept in economic feasibility,resource reuse,safety support,cross energy storage and development prospects are analyzed,as well as the urgent problems such as high cost,poor safety,and insufficient large capacity storage and transportation capacity.Finally,suggestions and prospects for the future development of electric hydrogen integration are put forward.
