摘要
Short-term load forecast plays a vital role in the electric power industry. In this paper, a deep belief network is proposed for short-term load forecasting. However, the Back-Propagation (BP) algorithm of deep belief network for fine tuning has some inherent drawbacks and limitations, such as slow convergence rate and easy to fall into local minimum. To overcome the drawbacks, several neural network weight optimizing methods are proposed and compared. Experimental results show that Levenberg-Marquardt (LM) algorithm has the highest accuracy.
