Optimal Configuration of Soft Open Point for Active Distribution Network Based on Mixed-integer Second-order Cone Programming

Soft Open Point (SOP) refers to a power electronic device installed in placeof a normally-open pointin a distribution network. The application of SOP will greatly promote the economy, flexibility and controllability of the distribution network. In this paper, anoptimal configuration method of SOP is proposed for the operation of active distribution system. Firstly, considering the characteristics of renewable energy generation, classic scenarios are constructed based on Wasserstein distance metric. Secondly, anoptimal configuration model of SOP is presented. Then,a conic modelconversion is proposed andmixed-integer second-order cone programmingis used to solve the model with efficiency and convergence. Finally, case studies on IEEE 33-node test feederareused to verify the proposed method.
