欧洲能源危机下英国电网电力保供措施对中国的借鉴启示

Inspiration of the UK ESO Power Supply Sustainability Measures under European Energy Crisis to China Power System Operator

俄乌冲突给欧洲能源供需格局带来深刻变革,英国电网2022年冬季的电力供应安全受到严峻挑战。英国电网在冬季来临之前,已对极端情况予以充分考虑,其中包括一次能源供给受阻叠加欧洲大陆电力支援能力不确定等情况,有针对性地提出了应对措施,并在每年定期的迎峰度冬报告中向社会发布,取得了积极成效。从中国源网分开经营、电力体制机制逐渐成熟、区域性供需结构矛盾不时发生的实际情况看,这种基于电网企业对能源电力供给极端情况的分析十分必要,在极端情景的分析范式、应急资源的充分储备、公共信息的及时发布方面,能够为中国新型电力系统建设下的电力保供工作提供充分借鉴。建议源网荷各方市场主体与政府部门协同发力,在电力系统极端情况运行模拟、需求响应资源准备和信息透明化建设方面取得更进一步的成效。

The conflict between Russia and Ukraine has brought profound changes to the European energy market,and the security of the electricity supply of the UK national grid in the winter of 2022-2023 has been severely challenged.Before the arrival of winter,the UK power grid has fully considered the extreme situation of the blocked supply of primary energy and the uncertainty of the power support capacity of the European continent,and put forward targeted countermeasures,which are released to the society in the annual report on the preparations for the peak of winter power demand,achieving positive results.From the de facto situation of separately-operated source and grid,gradually-matured power system and mechanism,and occasional conflicts in regional supply and demand structures in China,this kind of analysis of energy and power supply based on grid enterprises is very necessary,and it can provide sufficient reference for guaranteed power supply under the construction of new power system in China,in terms of the analysis paradigm of extreme scenarios,adequate reserve of emergency resources,and timely release of public information.It is suggested that the various source-grid-load players in market and the government departments work together,and achieve further progress in the operation simulation of power system under extreme conditions,the preparation of demand-responsive resources and the improvement of information transparency.
