【Abstract】 This paper proposed a bi-level planning model of AC/DC distribution network based on flexibility time series scenario. This model can maximize the flexibility of the system while taking into account the maximization of social and economic benefits. First of all,this paper proposed a method for constructing a typical time-series of system flexibility,and studied the typical timing characteristics of the flexibility requirement. Based on the time sequence of flexibility requirements,an upper-level model was established to obtain the optimal deployment plan for system flexibility resources,and a multi-objective particle swarm optimization algorithm based on grid partition was used to solve the scenario to build a time-series scenario of system flexibility resources. Under the optimal flexible resource timing scenario,the lower model performs AC-DC transformation on the original AC distribution network,which proves the superiority of the AC-DC distribution network in terms of social and economic benefits.更多还原
