极端天气下爱尔兰新能源高渗透场景调度经验及启示OA北大核心CSTPCD

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.
