The region-based method has been applied in transmission systems and traditional passive distribution systems without power sources. This paper proposes the model of total quadrant security region (TQSR) for active distribution networks (ADN) with high penetration of distributed generation (DG). Firstly, TQSR is defined as a closed set of all the $N$ -1 secure operation points in the state space of ADN. Then, the TQSR is modeled considering the constraints of state space, normal operation and $N$ -1 security criterion. Then, the characteristics of TQSR are observed and analyzed on the test systems with different DG penetrations. TQSR can be located in any quadrant of the state space. For different DG penetrations, the shape and security features of TQSR are also different. Finally, the region map is discovered, which summarizes the features of different types of distribution networks.

分布式发电渗透率高的有源配电网总象限安全区域

基于区域的方法已应用于没有电源的传输系统和传统的无源配电系统中。本文提出了具有较高分布式发电（DG）渗透率的有源配电网（ADN）的总象限安全区域（TQSR）模型。首先，TQSR被定义为所有$ N $ -1安全操作点位于ADN的状态空间中。然后，考虑到状态空间，正常操作和$ N $ -1安全性标准。然后，在具有不同DG穿透的测试系统上观察并分析了TQSR的特性。TQSR可以位于状态空间的任何象限中。对于不同的DG穿透，TQSR的形状和安全性特征也不同。最后，发现了区域地图，该地图总结了不同类型的配电网络的特征。
