区域电力市场:助力清洁零碳转型
- Wang Xuan ,
- Max Dupuy ,
- Fredrich (Fritz) Kahrl
2020年,中国各省在电力市场建设方面不断推进,一些地区已经初步建立了区域和省级相衔接的电力中长期交易体系,并加速向区域一体化现货市场方向发展。 七月份发布的国家能源局综合司《关于开展跨省跨区电力交易与市场秩序专项监管工作的通知》(国能综通监管【2020】72号)在工作目标中提出推进跨省跨区电力市场化交易,进一步实现资源在更大范围的优化配置,表明了中央政府对区域电力市场的持续关注和支持。… View Summary +

就国家能源局“十四五”能源发展规划的建议
2020年11月,国家能源局就第十四个(2021-2025)五年能源规划公开征求意见。我们获悉此消息后在极短的时间内做出了响应,本文在初始回复的基础上进行了修改和完善。我们主要针对能源规划中的电力规划环节提供了一些思路和建议。电力规划是考虑经济高效,清洁可靠的资源组合的重要平台。 制定退煤规划 鉴于中国政府最近宣布的(2030年前)碳达峰和2060年的脱碳目标,五年规划的一个关键主题应该是如何让电力行业走上一条远离燃煤发电的坚定转型之路。本文将基于国际经验和我们对中国正在进行的电改工作的理解,简要分享一些关于如何实现这一目标的建议。… View Summary +

储能如何参与市场?
- Fredrich (Fritz) Kahrl ,
- Wang Xuan ,
- Max Dupuy
正如世界上其他国家一样,中国电力行业要走向零碳发展的未来,需要有灵活性资源的支持。储能,特别是电化学储能,由于近年来成本大幅度降低,以及其多重应用价值,前景越来越光明。并网储能能够成本有效地发挥帮助可再生能源并网、提高剩余火电厂运行效率、提供调峰调频等辅助服务、管理电网阻塞、替代输配电设施、抑制价格波动等作用。根据CNESA储能项目库的统计,到2019年底,中国已投运储能项目累计装机32.3 GW, 其中抽水蓄能约30GW,电化学储能约1.6 GW。最近的一些… View Summary +

可再生能源如何参与电力市场?
- Fredrich (Fritz) Kahrl ,
- Wang Xuan ,
- Max Dupuy
随着中国政府提出的低碳、零碳观念的深入,电力行业首当其冲需要加速扩大清洁电力的渗透率。在各地区探索电力市场设计,逐步完善电力交易规则的新形势下,如何让以光伏发电,风能发电为代表的可再生能源以及新兴的储能资源参与市场是业界关心的话题。 我们前几篇政策短文就电力区域市场建设,区域市场之间的协调进行了讨论,在这一篇和下一篇短文中,我们会基于国际经验分别介绍可再生能源和储能参与电力市场的途径和步骤。 光伏发电和风能发电参与电力市场的三种模式 在之前的文章中,我们提出区域RTO是提供低成本灵活性的良好途径,从而更好地应对波动性可再生能源出力的不确定性。可再生能源在不同时间尺度更好地参与电力市场有利于电力系统稳定高效运行,支持低成本零碳转型。在美国RTO/ISO地区,可再生能源在过去的十多年一直积极参与电力市场,为形成风能和太阳能发电的“参与模式”积累了宝贵的经验。美国可再生能源主要参与三类市场竞争:远期市场(中长期市场)、电能量市场、辅助服务市场。 一、远期市场(中长期市场)… View Summary +

China’s Watchdog for State-Owned Enterprises Grapples With Coal-Fired Generation
The future of China’s power sector, which accounts for about a quarter of the world’s annual consumption of coal and a still-growing fleet of coal-fired generation units, is one of the central questions for world climate policy. Within… View Summary +

减少弃风:提高电力系统调度比改造燃煤电厂更高效
- Lu Hong ,
- Kevin Porter ,
- Max Dupuy
中国的风能和太阳能装机容量世界第一,且有望成为“世界可再生能源的超级大国”。然而,中国也遇到了弃风限电问题。虽然近年来可再生能源弃电量有显著下降,但在很多省份仍然存在问题,且将随着风能和太阳能发电装机量的增长而持续成为挑战。幸运的是,政府部门正在制定诸多应对的战略措施。成功的关键要看这些战略是否协调一致。 近来,刊登在“气候政策”上的… View Summary +

Improving Power System Dispatch Reduces Wind Curtailment More Effectively than Retrofitting Coal Plants
- Lu Hong ,
- Kevin Porter ,
- Max Dupuy
China has the most installed wind and solar capacity in the world and has potential to become “the world’s renewable energy superpower.” However, China’s power sector has also struggled with extensive curtailment of wind and solar generation. Although renewables… View Summary +
