针对主动配电网(active distribution network,ADN)运行优化模型的非线性问题,提出一种含线性化潮流约束的配电网运行优化模型.以购电成本和分布式发电运行成本最小为优化目标,考虑主动配电网中负荷的柔性特征,推导柔性负荷的数学模型.为提高模型的求解效率,采用分段线性化方法处理模型中的非线性潮流约束,从而将所提模型转化为混合整数线性规划(mixed integer linear programming,MILP)问题;最后,通过对IEEE 33节点和IEEE 69节点配电网的仿真分析,验证所提模型的有效性.
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.
