浙江近期出台新型主体市场化响应实施细则,明确用户侧储能独立参与响应。
中新网杭州10月9日电(鲍梦妮 张悦)据国网浙江电力10月9日消息,国庆假期,该公司组织虚拟电厂市场化填谷响应,吸引50家虚拟电厂运营商、2542户聚合用户参与,最大响应负荷359.52万千瓦,刷新国内虚拟电厂响应规模纪录。其中,用户侧储能方面有1359户参与,最大响应106.41万千瓦,储能响应规模同步创下国内新高。

国庆长假,浙江多数工商企业进入休假模式,全社会用电负荷较工作日明显回落;但遍布全省的光伏电站并未“休假”,午间光伏发电量集中释放,新能源消纳压力陡增。填谷响应就是引导可调负荷在午间光伏出力高峰时段多用电,就地消纳富余绿电。
此次响应刷新纪录,得益于浙江近期出台的《浙江电力领域新型主体市场化响应实施细则(试行2.0版)》《浙江省虚拟电厂运营管理实施细则(试行)》。按照新规,用户侧储能可作为独立单元参与响应,储能贡献单独核算、单独兑付,不再被企业减产后的负荷下降所抵消。
配套市场机制同步打通。今年9月,浙江省发展改革委、省能源局印发通知,明确经虚拟电厂聚合参与填谷响应的用户侧储能,可在响应日前一日19时至23时用电高峰时段放电上网,上网电量按当月同电压等级电网代理工商业购电电价结算.储能在晚间高峰腾出容量、获取收益,次日午间继续充电填谷,形成“谷充峰放”的每日滚动循环。
“过去,企业减产导致用电减少时,电网难以区分是生产调整还是储能调节,储能价值容易被掩盖。”国网浙江电力有关负责人介绍,如今,储能“午间充电填谷、晚峰放电腾容”的贡献能够被精准计量,企业参与动力明显增强。
10月1日,虚拟电厂统一下达调度指令,分布在浙江各地的可调负荷同步响应。在宁波鄞州,日月重工股份有限公司将10000千瓦储能接入虚拟电厂,累计填谷响应电量2万千瓦时;在嘉兴海宁,晶科能源(海宁)有限公司投入5000千瓦储能参与填谷。宁波、丽水、金华等地重卡充电站也接入虚拟电厂资源池,运用电价信号和响应激励机制,引导货运车辆将充电时间调整至电网负荷低谷的9时至11时,吸引货运车队有序错峰补能,让交通领域充电网络成为电网调节的“蓄水池”。
截至目前,浙江全省累计接入虚拟电厂运营商65家,聚合二级用户9852户,总可调能力超360万千瓦,调节容量相当于一座大型火电厂。应用场景已从最初的单一削峰,拓展为削峰与填谷双向调节;聚合资源类型从可调工业负荷延伸到用户侧储能、新能源汽车充电网络、商业楼宇、数据中心等多元场景。

Taipower's independent director Liao Huizhu pointed out that Taipower's cumulative losses may exceed 400 billion yuan, and advocated that a 71.1 billion yuan subsidy is more in line with the overall interests of the country. If the Legislative Yuan is unwilling to provide subsidies, the chance of an increase in electricity prices in December will greatly increase. She emphasized that Taipower has evaluated the possibility of restarting nuclear power, and called on Blue and White legislators not to insist on their own opinions in order to maintain the competitiveness of Taiwan's AI supply chain.

International oil prices closed up 4% on Thursday, with Brent crude oil rising 4.1% to US$104.28/barrel, and WTI rising 3.6% to US$91.49/barrel. The gains were driven by continued concerns about war in the Middle East and intensifying supply disruptions as Hurricane Isaias approaches the Gulf of Mexico. The United States has imposed new sanctions on Iran, and 62.9% of the Gulf of Mexico oil production capacity has been shut down. Oil prices fell from session highs after Trump promised not to attack Iran before the election.

Chinese researchers have developed a catalyst that converts synthesis gas into sustainable jet fuel, with a techno-economic analysis showing a gross profit margin exceeding 50% for a planned 100,000-tonnes-per-year plant, as reported in Nature Communications in September.

In the phase 3-3 selection of Taiwan's offshore wind power block development, only WoXu Energy and CIP bid, and the scene was deserted. Minister of Economic Affairs Gong Mingxin said that it is not convenient to comment during the current review process, but the government has instructed the inter-ministerial committee to take stock of the maritime space and continue to maintain contact with domestic and foreign developers to prepare for subsequent business selection.

In response to the Taipei High Administrative Court's decision to revoke the environmental impact assessment conclusion for the second phase of the Taichung Power Plant's gas-fired power plant, Taipower expressed its respect and will add evidence after receiving the judgment. It also emphasized that the second phase of the central power plant is the core of the national policy of increasing gas and reducing coal, and is related to whether existing coal-fired units can be decommissioned.

The Yunnan Bureau of the State Administration of Mine Safety released the investigation report on the "12·24" large coal and gas outburst accident in the Xiongdaying Coal Mine in Zhaotong Town. The accident killed 7 people and caused a direct economic loss of 15.962 million yuan. The investigation determined it to be a production safety accident, and recommendations for accountability were made to 40 responsible personnel.
