中新社北京11月13日电 (记者 刘亮)中国国家市场监管总局13日公布,中国牵头的虚拟电厂一次调频国际标准提案近日在国际电工委员会成功立项。该国际标准,聚焦虚拟电厂快速稳定电网的核心能力,联合多国专家制定全球统一技术准则,标志着中国在虚拟电厂国际标准化领域迈出关键一步。

虚拟电厂并非实体电厂,而是依托数字技术将屋顶光伏、储能电池、充电桩、可调空调等分散设备聚合,统一调度、协同运行。虚拟电厂虽无厂房和机组,却能形成可观的调节能力,为电网提供调峰、调频等辅助服务。电网安全稳定运行的关键,在于发电与用电实时平衡。风电、光伏出力具有波动性和间歇性,一旦发用电失衡,电网频率即发生偏移,轻则影响电能质量,重则威胁电网安全。

一次调频,就是电网要在短短几秒内快速调整发电出力、减小频率偏差的能力,是电网维持频率稳定的快速调节手段。电网调频过去主要依靠传统火电厂,现阶段,光伏、储能、电动汽车快速发展,数量多但个体容量小,只有通过虚拟电厂把它们聚合起来,才能成为参与调频的宝贵资源,就像给电网装上“减震器”,把波动“压”下去,既保障供电安全,又能更多消纳绿色电力。目前,全球尚缺乏虚拟电厂参与一次调频的统一技术标准,制约了这一新技术在世界范围内的推广应用。

本次立项正是要破解这一难题。依托青岛虚拟电厂建设支撑海量分布式电源接入消纳的成功经验,为世界各国开展虚拟电厂参与一次调频提供了“中国方案”。今后,各国建设虚拟电厂、检验设备性能都可以参照这套标准。

"Pikmin" officially writes "Taiwan, China", triggering a wave of withdrawals. Remember to do one thing before deleting your account.

The mobile game "Pikmin Bloom" announced in its Simplified Chinese version that "Taiwan" will be rewritten as "Taiwan, China". This, coupled with the operator's indirect relationship with Tencent, triggered a wave of withdrawals from Taiwanese players. Taiwanese players contributed nearly NT$600 million in the first half of 2026, making it the world's largest consumer market. After the incident broke out, the announcement on the Simplified Chinese website was changed to "Taiwan" in English.
