Abstract:With the expansion of power grid scale and the increase of power components, the maintenance methods of power system become more and more complex. It is difficult to evaluate the transient stability risk of power grid under massive maintenance only by traditional methods. To solve this problem, a risk assessment method of transient stability in maintenance power network based on long short term memory (LSTM) neural network is proposed. Firstly, the unified coding method of power system maintenance mode is proposed, so that the computer can quickly and accurately identify the operation state of power grid under various maintenance modes. Then, a long short term memory neural network is established and trained based on a large number of fault samples of the power grid under maintenance. After that, the accurate evaluation of the power grid transient stability under different maintenance modes is realized. Finally, a regional power grid in Central China is taken as an example to verify the accuracy of the proposed method.
