With the proposal of the concept of carbon neutrality in China, the market will continue to pay more attention to sustainable energy and energy conversion. The management of the power system is a very important part in this field due to the discontinuity of wind energy and solar energy, which is also called power dispatching. It is particularly important in the process of power system conversion and management, so it is very helpful to understand the development and bottleneck of power system to understand the main research content of power dispatching through literature. Based on machine learning and text mining, this paper analyses the related research of power dispatching. The results show that the related papers of power dispatching mainly include safe operation, power dispatching strategy, power dispatching automation, power dispatching technology analysis and so on. This paper also shows the results by a clear visualization method.
