在新型电力系统中,用户侧分布式能源与电动汽车等新型负荷大规模并网,导致负荷的随机扰动特性增强,需要考虑其对静态安全域的影响
并探索关键越限因素识别与边界更新方法。针对负荷随机扰动,提出面向负荷扰动的静态安全域迁移与修正的数据-模型混合驱动方法。该方法通过机器学习算法预测不同负荷下的静态安全域系数,根据预测结果构建迁移边界,并基于系统越限参数和改进损失函数实现静态安全域边界的在线修正,以适应主导边界变化的场景。通过IEEE 39节点系统的仿真,验证了所提静态安全域迁移与修正方法的高效性和准确性。
In new power systems
the large-scale grid integration of new loads such as distributed energy resources (DERs) on the user side and electric vehicles (EVs) has intensified the random disturbance characteristics of loads. It is necessary to consider their impacts on static security regions (SSRs) and develop the methods for identifying critical overlimit factors and updating boundaries. To address random disturbances on the load side
this paper proposes a data-model hybrid-driven method for SSR transfer and correction for load change scenarios. This method uses machine learning algorithms to predict SSR coefficients in various load states
constructs transfer boundaries based on the prediction results
and achieves the online correction of SSR boundaries based on system overlimit parameters and an improved loss function
thereby adapting to dominant boundary-change scenarios. Simulation on the IEEE 39-bus system validates the efficiency and accuracy of the proposed transfer and correction method for SSR.
