Abstract:In response to the shortage of flexible adjustment resources in the distribution network caused by the high proportion of new energy grid connection, this paper proposes a multi-flexible resource collaborative optimization dispatching method to improve the flexibility of the distribution network. Firstly, the supply-demand relationship of distribution network flexibility in the new power system is analyzed, and the interactive characteristics of source load storage flexibility resources are characterized. Then, taking into account the improvement of distribution network flexibility and economic operation, a multi-flexible resource collaborative optimization dispatching model is constructd. Finally, the effectiveness and adaptability of the proposed strategy are verified using the IEEE-33 node testing system.
