提出考虑风电不确定性和储能灵活性的有源配电网有功无功协同鲁棒优化方法。首先建立计及储能四象限功率可调特性的有源配电网有功无功协同优化模型;其次给出储能约束条件和交流潮流方程的线性化表征方式;然后利用盒式集描述风电出力的不确定性,建立有源配电网有功无功协同鲁棒优化模型,并通过对偶变换得到混合整数线性规划形式的两阶段鲁棒主、子问题,采用列约束生成算法交互迭代求解;最后以IEEE 33节点系统为例进行仿真验证。仿真结果表明,所提方法能够克服模型高度非凸非线性对其收敛精度和求解效率的影响,充分利用储能的无功调节能力,实现有源配电网有功无功协同鲁棒优化运行。

Abstract

This paper proposes a robust optimization method for active power and reactive power collaboration in active distribution networks considering wind power uncertainty and energy storage flexibility. Firstly, the active power and reactive power cooperative optimization model of active distribution network considering the adjustable power characteristics of energy storage devices in four quadrants is established. Secondly, the linearized representation of AC power flow equation and energy storage devices constraints are given. Then, by using the box set to describe the uncertainty of wind power output, the active power and reactive power cooperative robust optimization model of active distribution network is established. Through the dual transformation, the main problem and subproblem of two-stage robust optimization in the form of mixed integer linear programming are obtained, and the column constraint generation algorithm is used to solve the interactive and iterative problem. Finally, the IEEE 33 node system is taken as an example for simulation verification. The simulation results show that the proposed method can overcome the influence of high non-convexity and nonlinearity of the model on the convergence accuracy and solving efficiency, and make full use of the reactive power regulation ability of the energy storage devices to realize the robust optimal operation of active power and reactive power coordination in the active distribution network.
