20140156322 | Unified Framework for Electrical Load Forecasting - Techniques for forming and using a unified framework for electrical load forecasting are described herein. In one example, data is received from supervisory control and data acquisition (SCADA) measurements available in an electrical grid. Data may be validated using ramp rate filter and load level filter tests. An augmented Savistky-Golay filter may be used to smooth the data, which may then be passed to autoregressive near-term forecast model(s). Forecasts are generated using near-term, ramp rate and short-term models. The near-term and ramp rate forecasts may be combined, such as with forecast horizon and ramp rate horizon parameters, to create a stitched forecast. The stitched forecast and short-term forecast are then blended using a blending period and blending weights that may be supplied exogenously. The final blended or unified near-term and short-term forecast may be exported to downstream generation scheduling and dispatching applications, which may calculate electrical production. | 06-05-2014 |
20140289004 | Near-Term Data Filtering, Smoothing and Load Forecasting - Techniques for near-term data filtering, smoothing and forecasting are described herein. In one example, data is received from supervisory control and data acquisition (SCADA) measurements available in an electrical grid. The data may be filtered according to a two-stage Kalman filter, which may include a ramp rate filter test and a load level filter test. The filtered data may then be smoothed according to an augmented Savitzky-Golay filter. Within the filter, a lift multiplier may correct for bias, which may have been introduced by load changes (e.g., an early morning increase in load). In one example, the lift multiplier may be calculated as a ratio between a smoothed load from a centered Savitzky-Golay moving average and a right hand side constrained Savitzky-Golay moving average. The filtered and smoothed data may be used in forming near-term forecast(s), which may performed by autoregressive model(s). | 09-25-2014 |
