Reactive Power Optimization for Three-phase Distribution Networks with Distributed Generators Based on Mixed Integer Second-order Cone Programming
摘要
Abstract
The reactive power optimization in distribution networks with distributed generators is a nonlinear and non-convex problem in essence and one hard to get an optimal solution.In light of the radial operation characteristic of the distribution network,this paper develops a three-phase reactive power optimization model based on branch power flow equations.Then the original reactive power optimization model is converted to a mathematical programming form with a convex feasible zone based on the second-order cone relaxation technology. Further, the model is extended to a mixed integer second-order cone programming model by taking the discrete compensation devices (such as capacitors) into account.The model can easily be solved by existing optimization solvers.Numerical tests on an IEEE 33-bus and IEEE 123-bus distribution system show that the proposed method is capable of efficient global optimal solution.关键词
