“…This may motivate wind power producers to enhance forecasting accuracy for profit maximization. Positive and negative forecast deviation create almost similar financial impacts, therefore, deviation charges are usually calculated using absolute error and absolute percentage error [5,18,24]. Absolute Error (AE) and Absolute Percentage Error (APE) can be calculated using the following equations [24].…”

“…Deviation charges are estimated for different ranges of absolute percentage error as the impact on the system will be severe for higher deviation. Deviation charges are usually avoided for the APE range of 0 to 15 percent as it results in less impact and also for promoting green energy generation [5,18]. The deviation charge for the APE range of 15 to 25 % is calculated as,…”

“…This necessitates forecasting performance evaluation in terms of financial impacts such as deviation charges. There is only a little attention towards deviation charge-based forecasting performance evaluation [3,5,15,18]. Most of the system operations like real-time economic dispatch and power system flexibility requirement evaluations are done in very short time frames like 5/15/30/60 minute wise [23].…”

High penetration of wind power plants in power systems resulted in various challenges such as frequent system imbalances due to highly uncertain and variable wind generation. Additional spinning reserves and specific balancing products such as flexible ramp products are used to handle such frequent imbalances. Incorporation of these ancillary services leads to increased total operational costs. Increased operational costs should be transferred to wind power producers as it is caused by wind power plants. This leads to penalizing the wind power producers for the deviation of power generation from forecasts, called deviation charges. These deviation charges can be reduced by improving the forecasting accuracy. Existing forecasting models show performance in terms of error matrices. Such error matrices do not indicate the financial loss associated with it. This can be overcome by expressing forecasting performance in terms of deviation charge and it will directly encourage wind power producers to improve forecasting accuracy or arrange reserves to accommodate the error. This paper proposes a backpropagation-based artificial neural network model for reducing deviation charges in this context. An analysis is conducted on the data collected from the Bonneville Power Administration (BPA) Balancing Area. Seasonal analysis (Spring, Summer, Fall, and Winter) is conducted to show the performance of the proposed model throughout the year. The proposed model performance is compared with linear regression and ARIMA models. The comparison shows that the proposed ANN model gives the least deviation charges in the Spring, Summer, and Winter seasons and deviation charges in the Fall season are higher than the ARIMA model.
