主动配电网协调控制系统设计及应用

分布式电源的不断增多以及电动汽车等多样性负荷的发展,给配电网的运行控制带来了极大挑战。为充分发挥主动配电网的作用,适应智能电网的发展需求,提出一种主动配电网协调控制系统。文中详细阐述了系统总体架构设计、软件架构设计,以及包含特性分析、态势感知、协调控制在内的应用功能设计,通过实现电源、电网、负荷的互动协调控制,充分挖掘配电网中可调可控资源的潜力,在主动配电网安全可靠运行基础上,提升分布式电源的有效消纳以及多样化负荷参与电网调峰的能力。文中设计开发出的主动配电网协调控制系统已应用于常州配电网。

Design and Application of Coordinated Control System in Active Distribution Network

With constantly increasing accesses of distributed generators and diversity load development such as electric vehicles, the operational control of distribution network is facing a huge challenge. In order to make full use of active distribution network and meet the development requirement of smart grid, this paper proposes a coordinated control system in active distribution network. The paper elaborates the general architectural design, software architectural design, and functional designs including of characteristic analysis, situation awareness and coordinated control. Through the coordinated interaction and control of source-load-storage being realized, the potential of controllable resources in distribution network is fully exploited, distributed generator optimizes its power generation absorption and diversity load improves its ability of participating in electric network load adjustment basing on active distribution network in safe and reliable operation. The coordinated control system designed and developed based on this paper has been applied in Changzhou distribution network.
