新的IEEE 1547 - 2018标准包括用于光伏（PV）智能逆变器的动态电压/无功控制。虽然最近的研究已经解决了最佳逆变器调度的问题，逆变器和经典的电压/无功控制（VVC）调节系统之间的相互作用需要进一步研究。本文提出了一种方法，建立在经典的VVC解决方案与PV，通过计算每个逆变器的规则，调制智能逆变器的无功功率的功能，其真实的功率。提出了两种方法来计算逆变器的无功功率方程斜率：第一种方法是基于通过线性规划的绝对电压幅度偏差的鲁棒最小化，而第二种方法产生封闭形式的解决方案，从分布式鲁棒的机会约束的启发。数值结果表明，由于间歇性真实的功率变化的电压违规显着减少的决策规则相比，保持最后计算的VVC设定点，即使当逆变器在恒定的功率因数或默认电压/VAr设置在文献中提出的;此外，无功功率决策规则保持接近于集中式解决方案的平均值的网络损耗水平。
The new IEEE 1547-2018 standard includes dynamic Volt/VAr control for photovoltaic (PV) smart inverters. While recent research has addressed the problem of optimal inverter dispatch, the interaction between inverters and the classical Volt/VAr control (VVC) regulation system needs further study. This paper proposes an approach that builds on the classical VVC solution with PVs, by computing for each inverter a rule that modulates the smart inverter reactive power in function of its real power. Two approaches are presented for computing the inverter's reactive power equation slope: the first approach is based on the robust minimization of the absolute voltage magnitude deviation via a linear program, whereas the second approach yields closed-form solutions inspired from distributionally robust chance constraints. Numerical results are presented on weakly meshed distribution networks having up to 3146 nodes; they demonstrate that the voltage violations due to intermittent real power variations are significantly reduced by the decision rules as compared to maintaining the last computed VVC set-points, even when the inverters operate at constant power factor or with default Volt/VAr settings proposed in the literature; additionally, the reactive power decision rules maintain a network loss level that is close to the average from a centralized solution.
