Research On Optimal Power Flow of Active Distribution Network Based on Mixed Integer Second-order Cone Programming
Optimal power flow is a nonlinear optimization problem. It is because of its complex and cumbersome, high dimensionality, many constraints and many variables. Applying it to active distribution networks is also a hot research topic. This paper first establishes the optimal power flow model of the active distribution network to minimize the active loss; secondly, considering the controllable unit and switch state of the distribution network, the improved radial constraints and power flow constraints are used to transform, and after reasonable relaxation, it becomes a second order cone Constraint, establish mixed integer second order cone programming model. The Yalmip toolkit was used for modeling, and the Gurobi commercial algorithm package was used to solve and calculate it. Finally, the calculation results of the particle swarm optimization algorithm and the mixed integer second-order cone programming method are compared and analyzed through an example. It is proved that the mixed integer second-order cone method is more suitable for active distribution networks, and the efficiency and effectiveness of the method are verified. stability.
