IEEE算例已被广泛用于电力系统规划、运行等领域的仿真测试。然而,受限于数据隐私保护,研究人员难以获取实际电力系统发电与网架结构的公开数据集。为此,提出一种基于三代电网演化理念的新型输电网测试系统生成方法,构建反映实际电力系统特征的输电网测试算例。首先,建立基于N-1安全校核的输电网扩展规划模型。然后,针对电网不同发展阶段特征设置相应优化目标与约束条件,以模拟电网的演化历程。为提高模型求解效率,建立输电走廊待建线路的二进制表征方法,以减少模型0-1变量。最后,以某省电网为例,构建开源电力测试系统,并根据复杂网络的统计特性验证所构建算例的有效性,此外,将该算例应用于输电网结构优化中以验证算例的合理性。

The IEEE test case has been widely used for simulation testing in various fields such as power system planning and operation. However, due to data privacy concerns, it isn"t easy to access publicly available datasets of actual power system generation and network structures. To address the issue, based on the evolution concept of three-generation power grids, a new transmission test system generation method is proposed to build test cases that reflect actual power system network structures. Firstly, a transmission expansion planning model considering N-1 security constraints is established. Secondly, the optimization objectives and constraints are proposed according to the characteristics of different stages of network development to simulate the evolution process of the electricity network. To enhance the solving efficiency of the model, a binary representation method of transmission corridors is introduced to reduce the number of 0-1 variables. Finally, the provincial power grid is used as an example to verify the effectiveness of the proposed open-source power system dataset, according to the statistical characteristics of complex networks. The proposed dataset is also applied to optimal transmission switching for further verification.
