摘要
随着新能源渗透率逐年上升,风电与光伏出力的不确定性给系统带来的不良影响逐年增大。伴随着气候变化,极端天气频发将进一步提高新能源高渗透场景下的电力电量平衡难度,研究极端天气下的电力调度策略迫在眉睫。作为含高比例新能源的岛屿同步电网,爱尔兰同步网可以在极端天气中有效应对高风切机事件,以在超过70%非同步渗透率的新能源高渗透场景中安全运行,因此其极端天气应对策略有重要示范意义。首先比较了爱尔兰与广东电网极端天气运行场景,分析了二者极端天气运行场景的异同。接着总结剖析了爱尔兰在新能源高渗透场景中应对极端天气场景的调度方案,结合广东场景的特点从极端场景预警与应对策略、辅助服务产品和负荷侧管理三方面提出了爱尔兰新能源高渗透场景经验对极端天气下新型电力系统运行的启示。
As the penetration rate of new energy sources continues to increase,the uncertainty of wind and solar power outputs is increasingly affecting systems.With the frequent occurrence of extreme weather events owing to climate change,the difficulty of balancing the power output in high-penetration scenarios of new energy systems will further increase.Therefore,research on power scheduling strategies under extreme weather conditions is urgently required.As an island synchronous grid with a high proportion of new energy,the Irish synchronous grid can effectively handle high speed shut down(HSSD)events and safely operate in highly renewable energy penetration scenarios with more than 70%nonsynchronous penetration.Therefore,strategies for dealing with extreme weather conditions have significant demonstrative value.This study first compares the scenarios of extreme weather operation between the power grids of Ireland and Guangdong by analyzing their similarities and differences.It then summarizes and analyzes Ireland’s strategies for coping with extreme weather scenarios in highly renewable penetration scenarios.By evaluating the characteristics of Guangdong’s scenario,lessons are proposed from Ireland’s experience in the operation of new power systems under extreme weather conditions,focusing on extreme weather warnings,response strategies,auxiliary service products,and demand-side management.
