In order to meet the possible appearance of AC/DC hybrid topology in the future distribution network

a multi-period optimal scheduling model based on second-order cone programming is proposed for AC/DC active distribution network. Taking the minimum sum cost of purchase charge and distributed generator(DG)curtailment as the objective function

the proposed model aims at realizing active-reactive power combined optimal dispatch

and overcoming over-limit voltage and power flow through five active management measures. These active management measures consisting of distributed generator curtailment

capacitor bank(CB)adjustment

energy storage system(ESS)adjustment

voltage source converter(VSC)adjustment and distribution network dynamic reconfiguration are considered to solve the day-ahead scheduling problem of AC/DC active distribution network with high renewable penetration. Finally

the correctness of the proposed model is verified by a 50-bus case.
