A Power Forecasting Method for Ultra-Short-Term Photovoltaic Power Generation Using Transformer Model

Table 7

Different model experimental results error comparison (%).

	Transformer vs GRU			Transformer vs DNN
	MAE	MSE	MAPE	MAE	MSE	MAPE
Subset 1	−27.0	−32.7	−46.3	−27.0	−30.7	−51.0
Subset 2	−54.4	−55.5	−55.9	−54.6	−65.4	−41.7
Subset 3	−15.8	−17.7	−1.46	−31.4	−40.9	−28.0

(Note. If the value is negative, it means that the evaluation index of the experimental results decreases by the corresponding percentage.).
