This paper mainly describes that the proportion of new energy in the installed capacity of the Yunnan power grid system has reached about 32 From the perspective of the incremental energy layout in Yunnan Province,the proportion of new energy will soon gradually increase to around 35％.The volatility of energy due to weather changes and its lack of rotational inertia have already brought significant challenges to the stability of the power grid system's frequency.From the perspective of a hydro energy province,the author proposes measures such as opening compensation for hydro turbine generating units,increasing the differential investment rate,and narrowing the unit vibration zone,can provide references for effectively improving the stability of the power grid frequency.
