A Study on Autonomous Decentralized Voltage Profile Control Method in Future Distribution Network considering Control Priority

在含有大量分布式电源的配电网中，维持系统电压成为一个重要的问题。在他以前的工作中，我们已经开发了一种使用逆变器无功功率控制的自治分散电压控制方法。在本研究中，我们提出了一种新的方法，可以有效地利用逆变器的空闲容量，通过虚拟复制的控制系统。此外，为了降低配电网的网损，还提出了高低压配电网协调控制的方法。

In the distribution network with a large amount of distributed generators, it becomes important issue to maintain the system voltage. We had been developed an autonomous decentralized voltage control method using reactive power control of inverter in his previous works. In this study, we proposed a new method which can utilize the free capacity of inverter effectively by duplicating the control system virtually. Additionally, the cooperative control method between high and low voltage distribution systems is also developed in order to reduce the distribution power loss.
