Abstract:By utilizing the normalization for the input load values of BP neural network and adopting Levenberg-Marquardt algorithm, this paper established an improved BP neural network and investigated the power system short-term load forecasting. Levenberg-Marquardt algorithm improves the convergence speed and the load forecast accuracy. The simulation results show that the improved BP neural network can offer higher forecast precision and has greater applicability. |
