| 摘要: |
| 近年来全球多个国家提出了碳中和战略目标，能源系统的转型与变革已迫在眉睫。在能源系统低碳化转型路径中，高比例新能源渗透充当了极为重要的战略角色，且各能源系统之间的转型呈现相辅相成、协同发展的趋势。一方面，新能源可通过电转气、电转热、电制氢等能源耦合设备分别为天然气、热力、交通侧等负荷提供绿色能源供应，终端用能的电气化改善了终端能源结构；另一方面，多能源系统的灵活性及多能互补性为间歇性新能源并网的消纳提供了支撑。为此，综述了面向碳中和目标的能源系统转型与变革的多能流协同技术，介绍了高比例新能源渗透下的多能流协同技术，剖析了支撑新能源并网的多能源市场机制设计，最后归纳总结了未来能源系统转型与变革面临的核心挑战。 |

| Abstract: |
| In recent years, many countries around the world have proposed the carbon neutral strategic goal. Hence, the transition and revolution of energy systems are urgent. The high penetrations of renewable energy act as a paramount role towards the pathways to low carbon energy systems. Moreover, the transition among multiple energy systems has become mutually beneficial and coordinated development. On the one hand, renewable energy can provide natural gas, heat, and transportation demands with green energy supply through multi-energy conversion units including power-to-gas, power-to-heat and power-to-hydrogen. The electrification of the user-side energy demands contributes to improving the energy mix. On the other hand, the flexibility provided by multi-energy systems and multi-energy complement can contribute to the accommodation of intermittent renewable energy production. Therefore, the application of multi-energy flow coordination techno-logy to carbon neutral oriented transition and revolution of energy systems is reviewed. The multi-energy flow coordination technology under the high penetrations of renewable energy is introduced. Then, the design of multi-energy markets for supporting the integration of renewable energy is analyzed. Finally, the core challenges of transition and revolution of energy systems in the future are summarized. |
