Abstract

A new approach to achieving volt-var control through the use of fast-acting distributed hybrid power electronics devices at the grid edge is proposed. It is shown that there is a missing layer of control at the grid edge which the conventional approaches do not address. Through field demonstration of 91, 10 kVAR devices on a 13 kV, 6 MW feeder, up to 5% CVR, 72% reduction in voltage volatility, 80% reduction in voltage unbalance and feeder level dynamic var control using the proposed grid edge control is presented.

电网边缘控制:一种新的伏无优化方法
提出了一种通过在电网边缘使用速效分布式混合电力电子器件来实现电压无功控制的新方法。结果表明,在网格边缘有一个缺失的控制层,这是传统方法无法解决的。通过在13 kV 6 MW馈线上910,10 kVAR装置的现场演示,提出了采用该电网边缘控制的馈线级动态无功控制,CVR可达5%,电压波动率降低72%,电压不平衡降低80%。
