Challenges and Prospects of Generalized Wind-Hydrogen-Coal Energy System

面向风煤富集区域的能源转型目标,对风-氢-煤能源系统(WHCES)的研究成果及其存在的问题进行了总结,以此为基础提出了广义风-氢-煤能源系统(G-WHCES)的基本概念和总体框架,阐述了其与WHCES在一次能源侧、二次能源侧及负荷侧的差异;面向风煤富集区域的能源转型战略,对其需求与应用进行了归纳总结;提出伴随系统内新能源比例升至一定高度,调节资源缺乏的情况下G-WHCES发展所面临的主要挑战,指出需要在系统运行效率和稳定运行方面给予更多关注,从系统结构设计、规划与控制、关键子系统和系统集成等方面对G-WHCES的科学与技术问题进行了展望。

Facing the energy transformation goals in wind-rich or coal-rich areas, the research results and existing problems of wind-hydrogen-coal energy system(WHCES) are summarized. Based on this, the basic concept and overall framework of generalized wind-hydrogen-coal energy system(G-WHCES) are proposed. The difference between G-WHCES and WHCES is compared on primary energy side, secondary energy side and load side. Facing the energy transformation strategy in wind-rich or coal-rich areas, the needs and applications of G-WHCES are summarized. In the case of high renewable energy penetration and insufficient regulating resource, the main challenges in the development of G-WHCES are proposed. The results indicate that more focus should be concentrated on the operation efficiency and system stability and the prospects of scientific and technological issues for G-WHCES are given on the system structure design, planning and control, key sub-system design and system integration.
