英国新型电力系统频率管理及对中国电网建设的启示OA北大核心CSTPCD

The United Kingdom(UK)stands out as one of the countries with the highest penetration of renewable generation globally,and the distinct features of the new power system have already been apparent in the UK.Exploring the achievement and experience of National Grid Electricity System Operator(ESO,the operator of UK power grid)in terms of frequency management holds great reference value for the construction of China's new power system.Firstly,the risks and mechanisms underlying frequency management challenges faced by the ESO in the construction of the new power system were investigated.Subsequently,the strategies and practical experiences adopted by the ESO to address these risks were analyzed.Finally,insights were explored regarding the ESO's approaches and practical experiences in frequency management,to provide valuable lessons for frequency management in the construction of our country's new power system.Following the UK's frequency management mechanism and construction roadmap of the ancillary service market,China could focus on improving the frequency management mechanism,investigating the system inertia requirements,and development and application of frequency support technologies.Moreover,developing the standards in advance to avoid the trip risk of large amounts of distributed generation.
