Abstract

To mitigate the impact of distribution system service quality due to high penetration of PV systems, a Distribution Renewable Energy Advanced Management System (DREAMS) is developed and installed at Feng Shan District of Taiwan Power Company (Taipower). The PV gateways and the public 4G communication system are applied to monitor the power generation and the voltage of 24 PV systems and to report the operation data to the master station. The power factor for the PV smart inverter is adjusted automatically to absorb the reactive power when the overvoltage problem occurs. When the distribution automation system (DAS) performs the functions of noninterruptible load transfer and service restoration after fault contingency, the DREAMS executes the power factor control for the PV smart inverters before the line switches are operated. The coordination control of DAS and DREAMS can prevent the overvoltage problem for a distribution system during the process of load transfer between distribution feeders with high PV penetration.

配电系统可再生能源综合控制与故障恢复

为减轻光伏系统的高普及率对配电系统服务质量的影响，台湾电力公司凤山区开发并安装了配电可再生能源先进管理系统(DREAMS)。采用光伏网关和公用4G通信系统对24台光伏发电系统的发电量和电压进行监测，并将运行数据上报主站。光伏智能逆变器自动调节功率因数，在出现过电压问题时吸收无功功率。当配电自动化系统(DAS)执行故障后不间断负荷转移和业务恢复功能时，DREAMS在线路开关运行前对光伏智能逆变器执行功率因数控制。通过DAS与DREAMS的协调控制，可以有效地防止高光伏渗透率配电馈线间负荷转移过程中出现的过电压问题。
