智能电网倡议基于几个支柱，其中集成各种分布式发电(DG)尤为重要。大量分布式发电机组在负荷之间的连接可能会导致严重的电压调节问题，而公用事业侧的电压调节器可能不再能够使用传统的控制技术。此外，智能电网应提供监测、自动控制和双向通信设施等新的数字技术，以提高网络的整体性能。本文将这些技术应用于智能配电网馈线的分布式控制中，构建了能够提供适当电压调节的分布式控制系统。根据智能代理的概念以及各个分布式发电机组和公用事业调节器的特点，定义了每个控制器的功能。为了验证所提出的控制结构的有效性和鲁棒性，建立了实时仿真模型。仿真结果表明，该分布式控制结构具有较好的抑制分布式电源设备与电网电压调节器之间干扰的能力。
Smart grid initiative is based on several pillars among which integrating a wide variety of distributed generation (DG) is of particular importance. The connection of a large number of DG units among loads may result in a severe voltage regulation problem and the utility-side voltage regulators might no longer be able to use conventional control techniques. In addition, smart grid should provide new digital technologies such as monitoring, automatic control, and two way communication facilities to improve the overall performance of the network. These technologies have been applied in this paper to construct a distributed control that has the capability to provide proper voltage regulation in smart distribution feeders. The functions of each controller have been defined according to the concept of intelligent agents and the characteristics of the individual DG unit as well as utility regulators. To verify the effectiveness and robustness of the proposed control structure, a real time simulation model has been proposed. The simulation results show that distributed control structure has the capability to mitigate the interference between DG facilities and utility voltage regulators.
