A Gray RBF Model Improved by Genetic Algorithm for Electrical Power Forecasting

Yilong Li  Qiang Gao  Dahua Li  
【摘要】:In order to improve electrical power forecasting accuracy of the Energy Internet this paper proposes a gray RBF model improved by genetic algorithm. This method forecasts power of the micro-grid using the characteristics that gray model can weaken data randomness and RBF neural network is highly nonlinear. Considering the problem of local optimum and convergence the paper uses genetic algorithm for net optimization. The micro-grid monitoring data are utilized to forecast the electricity load and the renewable energy output power in the proposed method. Compared to the traditional RBF model prediction, the undying method can provide higher precision and more excellent adaptability.
