基于大数据的电网调度系统可靠性研究

为了提高电网调度系统的性能,文中提出了基于大数据的电网调度系统可靠性研究方法。利用大数据技术对电网调度系统的各项数据进行深入挖掘,并利用改进权熵法对各项数据进行综合整理。与越限电压风险法相比,改进权熵法对于电力调度系统的考量更为周全,在风险评估的过程中不仅考虑了电压越限的风险,而且同时兼顾了电力电压分布造成的风险因素。整个系统的灵敏度更高,更适合用于电网调度系统的可靠性研究。

Research on reliability of power grid dispatching system based on big data

In order to improve the performance of power grid dispatching system,a research method of power grid dispatching system reliability based on big data is proposed.Big data technology is used to deeply analyze the data of power grid dispatching system,and the improved weight entropy method is used to comprehensively sort out the data,and the method is compared with the over limit voltage risk method.The improved weight entropy method has more comprehensive consideration for power dispatching system,not only considering the risk of voltage overrun,but also considering the risk factors caused by power voltage distribution in the process of risk assessment.The system has higher sensitivity and is more suitable for the reliability research of power grid dispatching system.
