本文提出了一种基于逆变器容量和对关键节点灵敏度的无功管理新方法。该方法解决了当住宅可再生能源(如屋顶太阳能电池板)产生的能量超过当地负荷需求时的电压上升和反向潮流问题。通过对无功潮流的主动管理来控制过电压问题。该方法在充分利用逆变器无功容量的同时，提高了可再生能源渗透率高的分布式系统的电压调节能力。
In this paper, a new approach for reactive power management based on inverter's capacity and sensitivity to the critical bus has been presented. The approach addresses the voltage rise and reverse power flow issue when residential renewable energy sources such as rooftop solar panels produce more energy than the local load demand. The overvoltage issues are controlled by active management of reactive power flow. This method improves the voltage regulation of distributed system with high penetration of renewable energy sources while utilizing the inverters' reactive power capacity.
