摘要
为了提高新型电力系统静态安全域构建效率,增强电力系统安全性分析与预防控制能力,提出基于邻域决策树的新型电力系统静态安全域边界通用搜索模型。利用C4.5决策树算法递归并分类新型电力系统安全域样本集,得到电力系统中静态安全域的范围;以搜索热安全域边界(TSRB)、电压安全域边界(VSB)与电压稳定域边界(VSRB)上的临界点为目标,构建新型电力系统静态安全域边界通用搜索模型;利用边界追踪方法搜索3个区域临界点,实现新型电力系统静态安全域边界搜索。实验证明该模型可以有效搜索到新型电力系统中热安全域、电压安全域以及电压稳定域边界,相对误差小,搜索精度高,具有较强的应用价值。
In order to improve the efficiency of the construction of the new power system static security region and enhance the power system security analysis and preventive control capabilities,a new general search model for static security region boundary of power systems based on neighborhood decision tree is proposed.The C4.5 decision tree algorithm is used to recurse and classify the sample set of the new power system security region,and the range of the static security region in the power system is obtained.Aiming at searching the critical points on thermal security region boundary(TSRB),voltage security region boundary(VCRB)and voltage stability region boundary(VSRB),a new general search model of static security region boundary of power system is constructed.The boundary tracing method is used to search the three critical points of the region to realize the boundary search of the static security region of the new power system.Experiments show that the model can effectively search the boundary of thermal security region,voltage security region and voltage stability region in the new power system with smaller relative error and higher search accuracy.It has stronger application value.
