摘要
大量可再生能源接入电网给配电网的控制带来了巨大挑战,传统配电网的被动控制已经不能满足对配电网能量双向流动的实时控制,发展研究主动配电网分层分布控制能实现对可再生间歇式能源的有效消纳及控制。文中将主动配电网(ADN)划分成3层控制结构,根据全局优化及馈线控制误差(feeder control error,FCE)提出定交换功率控制、区域协同控制、区域自治控制3种模式及它们之间进行主动切换的条件、方法。最后通过MATLAB/Simulink建立一个简单的ADN配电系统模型进行仿真,算例仿真结果验证了这3种模式之间切换的正确性及有效性。
A large number of renewable energy sources which connected to the grid has brought enormous challenges for power control. Traditional passive control of distribution network has been unable to meet the real- time control which needs two-way flow of energy in distribution network. The research of hierarchical and distributed control active distribution network can achieve that intermittent renewable energy will be consumptive effectively and control. In this paper, the active distribution network （ADN） is divided into 3 layers of control structure. According to the global optimization technique and the control error feeder （FCN）, 3 kinds of modes including the conditions and methods are proposed, which are constant exchange power mode, regional coordinate control mode and the regional autonomous control mode. At last, a simple ADN distribution system model is built by MATLAB/simulink. The simulation results verify the correctness and effectiveness of the 3 modes＇ switching.
