With　the　continuous　advancement　of　new　power　system　construction，the　impact　of　uncertainty　is　becoming　increasingly　prominent.　Consequently，it　is　urgent　to　enhance　the　flexibility　of　new　power　systems　to　respond　to　fluctuations　in　source　load　power　and　ensure　the　safe　and　stable　operation　of　the　system.　To　this　end，this　paper　reviews　methods　for　improving　the　flexibility　of　new　power　systems　considering　distributed　resources.　Firstly，based　on　the　inherent　characteristics　of　the　new　power　system，the　challenges　and　technical　bottlenecks　in　improving　the　flexibility　of　the　new　power　system　are　analyzed.　Secondly，following　the　historical-current-future　timeline，this　paper　summarizes　the　flexibility　improvement　paths　of　the　new　power　system　from　three　perspectives：flexibility　quantification　evaluation，flexibility　optimization　scheduling，and　flexibility　configuration　planning.　Finally，the　key　challenges　in　enhancing　the　flexibility　of　new　power　systems　are　summarized　from　the　three　aforementioned　aspects.　©　2025　Editorial　Department　of　Electric　Power　Engineering　Technology.　All　rights　reserved.
