In electricity market, electricity price is one of the main concerns for both suppliers and consumers. However, uncertain factors which effect electricity prices make it difficult to forecast them. This paper proposes a time series forecasting model which integrates K-Nearest Neighbor (KNN) and Artificial Neural Network (ANN) algorithms. The KNN algorithm is used to search for similar time subseries (neighbors) in historical data and the IA is used to search for the optimal weights on these neighbors. The model is tested by using dataset of the electricity price in New York electricity markets. Compared with traditional ARIMA and Naive I model, our model can get more accurate forecasting results.
