Abstract :
A RBF neural network considering the critic mechanism is introduced to predict the system marginal price (SMP). The system consists of three elements, which are a predictor, an evaluator and a learning machine. The predictor is used to forecast the future SMP. The estimator is used to evaluate the prediction´s validity. The explorer is used to determine the predictive step length. And the learning machine is used to keep the predictor self-learning. So the predictor can conform to SMP by self-learning and be in a good forecasting state. The simulation shows the proposed method has higher forecasting accuracy in irregular SMP cases than the conventional method has.
