Under the background of“Peak carbon dioxide emissions- Carbon neutrality”strategy, power system is facing aserious triangular contradiction of clean energy, high reliability and low cost. For the power system with significant coupling of multiple uncertainties, safe and reliable adjustment ability and flexible consumption margin of green energy have become important research orientations. Aggregation architecture technology oriented-to new type power system is the key technical solution. It can mobilize“sleeping”flexible resources, characteristics of which are not only numerous, flexible, dispersed but also hard to observe, hard to predict and hard to control, and provide important dispatch able resources for new power system. For the aspect of research and practice, the related work is still in the initial demonstration stage.Based on the typical cases of power system operation assisted by flexible resources all over the world, the types of aggregation architecture technology oriented to new power system are sorted out and their technical feature and tendency are analyzed. What’s more,the development suggestions and construction enlightenment of architecture technology for flexible resource participation in power system operation are put forward, which provide important technical support for the construction of power system with new energy as the main body in China.
