摘要：
The wide application of flexible interconnection devices brings great challenges to the planning of active distribution network(ADN). This paper proposes a novel ADN expansion planning method considering the integration of soft open point(SOP), in which the investment of substation, transmission line construction, SOP, distributed generation, energy storage and reactive power compensation are planned coordinately. First, an improved Gaussian mixture model clustering method is adopted to deal with the uncertainties of the power of distributed generation and load demand. On this basis, an expansion planning model for ADN considering the integration of SOP is established, whose objective function is to minimize the annual comprehensive cost. Then, the original non-convex and nonlinear model is transformed to a mixed-integer second- order cone programming(MISOCP) model by linearization and convex relaxation techniques, and a successive contraction convex relaxation algorithm is developed to obtain the optimal solution of the original problem with a sufficiently small relaxation gap. Finally, the feasibility and effectiveness of the proposed planning model and solving strategy are verified on a 54-bus ADN. © 2023 Chinese Society for Electrical Engineering. All rights reserved.
