Operation Optimization of Active Distribution Network Considering Linearized Power Flow Constraints
摘要
Abstract
This paper considered the nonlinear problem of the active distribution network(ADN)operation optimization model.A distribution network operation optimization model with linearized power flow constraints is proposed.Considering the flexible characteristics of the load in the active distribution network,a mathematical model of the flexible load is established,which aims at minimizing the total cost of power purchase cost and distributed generation operation.In order to improve the solution efficiency of the model,a piecewise linearization method is used to deal with the nonlinear power flow constraints in the model,and then the proposed model is transformed into a mixed integer linear programming(MILP)problem.Finally,the simulation analysis is carried on with IEEE 33-bus and IEEE 69-bus distribution network to verify the validity of the proposed mode.关键词
