Abstract
High proportion of grid-connected photovoltaic system brings new problems and challenges to the optimization of active and reactive power in distribution networks.Therefore,a multi-obj ective coordinated optimization model of active and reactive power based on the mixed integer second order cone programming is proposed.Firstly,a mixed integer nonlinear programming problem is relaxed into a mixed integer second order cone programming problem by using the second order cone relaxation technique.Secondly,theε-constraint method is utilized to characterize the Pareto efficient frontier of multi-obj ective problem.Thirdly,this problem is decomposed into a linear programming master problem with 0-1 integer variables and a second order cone programming sub-problem with continuous variables by means of Benders decomposition method.Moreover, the master problem and sub-problem use Benders cut as a bridge to alternately iterate until the result converges to an optimal solution.Finally,the numerical simulation is performed in the improved IEEE 33-node distribution system,and the results show the effectiveness of the proposed model.关键词
