摘　　要：随着“双碳”目标的提出并持续推进,电力系统向清洁型方向转变的需求更加强烈,更多的新能源出力将代替常规发电机组出力,导致系统的稳定性发生改变。基于瞬态能量函数法对常规机组被新能源机组取代后的电力系统的暂态稳定性进行分析,探讨新能源比例不断提高对电力系统造成的影响,并提出改善策略。With the proposal and continuous advancement of the“dual carbon”goal,the demand for the transformation of the power system to a clean direction is stronger,and more new energy output will replace the output of conventional generator sets,resulting in changes in the stability of the system.Based on the transient energy function method,the transient stability of the power system after the conventional unit replaced by the new energy unit is analyzed,the impact of the increasing proportion of new energy on the power system is discussed,and the improvement strategy is proposed.

关 键 词：新能源电力系统 瞬态能量函数法 暂态稳定性 改善策略
