摘　　要：考虑有源配电系统在运行经济性和安全性方面的要求,以及功率不确定性对系统运行的影响,提出基于场景分析的有源配电系统有功无功协调鲁棒优化策略。首先考虑系统中可调资源的有功无功功率极限,建立有源配电系统确定性有功无功协调优化模型,在此基础上,考虑功率预测误差对有源配电系统决策的影响,建立考虑不确定性的协调优化模型,采用场景分析方法生成典型场景集,从中寻找可能出现的最恶劣场景,并求得其对应的有功无功协调鲁棒优化调控策略。通过IEEE 14节点配电系统算例结果验证所提方法在应对功率波动不确定性方面的鲁棒性,以及有功无功协调优化在提升系统安全性方面的优势。This article takes the requirement of economic and security operations of active distribution systems into consideration,and puts forward a coordinated robust optimization strategy for active and reactive power in active distribution system on the basis of scenario analysis. Firstly,a coordinated multi-period optimization model of active and reactive power based on second-order cone programming is established with the consideration of controllable resources power characteristics.Based on this model,this paper puts forward a robust coordinated optimization of active and reactive power with the consideration of reducing the negative effect of energy uncertainty on the system. By generating typical scenario sets,the robust strategy can obtain the robust control policy for the active distribution system in extreme scenarios. Numerical tests on the modified IEEE 14 distribution system showthat the proposed strategy can make the system stable.
