摘要
针对新型电力系统下传统调度自动化系统可扩展性和决策前瞻性不足等问题,提出新一代调控系统预调度方法.在描述子系统层建立能够反映电网一次设备、二次设备和环境等状态的电网数字孪生体;在预测子系统层,电网数字孪生体基于电网运行数据进行深度学习,并预测电网运行的未来态势和事故风险;以华东电网新一代调控系统的预调度试点应用为例,验证所提方法的可行性.应用结果表明:该预调度方法提高了系统处理新型电力系统运行控制问题的效率,可以为新一代调控系统的全面建设和推广应用提供有益参考.
To meet the demand of scalability and decision-making foresight of the traditional dispatching automation system in the new power system, a novel pre-dispatching method of new generation dispatching and control was proposed. First, the power grid digital twin was established in the description subsystem layer, which can reflect the state of power grid primary equipment, secondary equipment, and environment. Then, in the prediction subsystem level, the deep learning models were used to learn and predict future situation or accident risk of power grid operation in power grid digital twin. Finally, the feasibility of the proposed method was verified by the implementation example of East China Grid. The application results show that the pre-dispatching method improves the efficiency of system in dealing with the operation control problems of the new power system, which also provides a useful reference for comprehensive construction, popularization, and application of new generation power systems.
