DG Locating and Sizing in Active Distribution Network Considering Network Reconfiguration

What is it about?

The traditional distributed generation (DG) locating and sizing method is based on a fixed network structure, which is assumed to be unchangeable during the planning period. The flexible distribution network structure is not considered. This paper proposes a novel method for DG locating and sizing in active distribution network (ADN), which mixes DG locating and sizing problem and distribution network reconfiguration problem together. The objective is to minimize the total costs of the distribution network in the planning period. DG locating and sizing considering network reconfiguration is a complex mixed-integer non-linear programming problem. This paper convert the dual-level planning model to second-order cone programming (SOCP) model, which can be solved with commercial solver GUROBI. The proposed model and method are testified with the modified IEEE 33-bus system.
