从电力规划看煤电产能过剩和可再生能源弃电的问题
最近几个月,中国政府为解决可再生能源弃电和煤电机组投资过度双重挑战颁布了一系列政策。特别是国家发改委,国家能源局《关于做好风电、光伏发电全额保障性收购管理工作的通知》(发改能源【2016】1150号)和《关于促进我国煤电有序发展的通知》(发改能源【2016】565号)。这些政策可能在近期会取得一些实质性的进展,然而它们并没有涉及到背后更深层次的问题,即增加系统灵活性的需求,改革对发电商的补偿机制,而是依赖于一些固化的手段:保障风电和太阳能光伏发电的年运行小时数,以及暂缓建设和批准电力盈余省份的煤电项目。 与此同时,国家能源局六月份发布了《电力规划管理办法》,这可能最终会对改善可再生能源并网和减少煤电过度投资起到更重要的作用。这个文件为制定更好的电力行业规划建立了框架,承诺要从以满足快速电力需求增长为首要目标的模式向更复杂地权衡多目标的发展模式转变,包括支持可再生能源发展,实现电力系统安全可靠、经济合理、清洁环保等。… View Summary +

Excess Coal Generation Capacity and Renewables Curtailment in China: Getting With the Plan
In recent months, the Chinese government has issued several high-profile policy statements directed toward the twin challenges of renewable energy curtailment and runaway investment in coal-fired capacity. These new policies appear to signal policymaker interest in dealing with… View Summary +

近年来,随着我国经济发展,能源消费不断增加,这一方面保障了我国经济发展和人民生活水平的提高,另一方面也带来巨大的污染物排放,对环境和人民身体健康的破坏日益严重。电力行业是能源消费和污染物排放的大户,是全国节能减排工作的重点。过去几年中,提高能效、加强火电厂污染排放治理以及发展清洁能源等措施都加快了电力行业的低碳化。 然而电力行业节能减排工作仍有很多问题,包括电力行业不同电厂的能效水平存在巨大差别,但是高能效机组和低能效机组利用小时相近,没有区别对待;风电和光伏建设迅速,但是其利用状况堪忧,已在部分地区出现大面积弃风弃光的现象,抵消了可再生能源发展的效果;电力行业盈利水平波动过大,导致对投资预期不确定,电力企业纷纷跨行业投资,影响了电力行业的稳定发展。 最近,长策智库受睿博能源智库委托完成了… View Summary +

将可再生能源纳入中国电力体系:技术入门

尽管就中国可再生能源存在海量的文献,但人们对中国电力行业基本机构的设置和运行,及其如何构成可再生能源扩展和并网的约束,缺乏足够的了解。本篇文章作为三个技术启蒙读本之一,旨在填补这一空白,文章主要针对电力系统的运作—在电力系统物理限制下匹配电力需求和供应展开论述。 中国电力系统在经济、社会、政治的综合作用下逐渐演变,最终形成了独特的运作机构和运行模式。设计这些机构和运行模式,用于支持主要由重工业需求主导和煤电作为基荷的电力系统。其中许多地方需要做出改变,来接纳充满活力的中国经济日益多元化的需求,并实现政府基于大量可变的风电和太阳能发电的低碳电力供应远景。 本文指出目前电力系统的运行没有达到系统在更高比例风电和太阳能下所需要的灵活性的需求。特别地,年度发电量计划、行政性的负荷控制、跨区和跨省电量交易安排、缺乏透明的调度系统阻碍了可再生能源的有效利用。因此,本文为朝向更具有灵活性的电力系统迈进,提出以下几点建议: 实现省级以及跨省平衡区内更经济的发电机组排序和调度; 建立更符合电力系统需要的辅助服务定义和规则;… View Summary +
