东北负电价破局之路（上篇） 当前，东北地区承担电力系统调节任务的主要是煤电机组，而这些机组绝大部分同时承担着民生供热职 责，由于尚未实现热电解耦，"以热定电"的刚性约束贯穿整个供暖季——发电负荷必须服从供热需求， 发电与供热形成强耦合的技术特性，使得热电联产机组的最小技术出力从非供暖季的25%大幅上升至 45%，调节空间被严重压缩。与此同时，10月起东北进入大风季，风电利用小时数较夏季提升30%，进 一步加剧了电力供需失衡，负（零）电价的持续出现，成为这一矛盾的直接体现。 二、破局关键：激活需求侧潜力，以采暖革新化解供需矛盾 破解东北负电价困局，供给侧的热电解耦是重要支撑，需求侧的潜力激活更是关键抓手，而推广商业化 电采暖，正是实现这一目标的核心路径——通过引导用户侧采用电采暖，精准匹配新能源大发时段的电 力供给，可将负电价这一市场"痛点"，成功转化为清洁供暖的核心"卖点"。 东北冬季最显著的能源特性，便是"供暖季与大风季高度重合"，这一天然优势为商业化电采暖的大规模 推广提供了绝佳条件，也为破解电力供需失衡打开了突破口。进入供暖季，东北区域同步迎来大风季， 风电出力大幅提升，形成新能源大发态势，而此时也正是 ...
