  3. Objectives • Create an inexpensive, real-time, and accurate solar insolation forecasting map. • Targeted for use by power companies to efficiently stabilize the power grid with solar generated energy. • Make large scale use of PV arrays more feasible and reliable. B. DiRenzo

  4. Background • Up to 40% of power can be supplied by solar energy (eg Hawaii). • Cloud cover creates major drop-off in energy production. • Leads to grid being unstable. • Similar methods exist for wind energy. • Unreliability limits use of on-grid PV arrays. B. DiRenzo

  5. Power Output (W) From a PV Array on a Cloudy Day vs. a Sunny Day *PV data provided by Professor Gasiewski L. Hager

  6. System Overview • Remote smart-phone sensors • Transmits photos of cloud coverage • On-grid PV array power sensors • Transmits real-time power measurements • Localized server • Parses data and computes forecast using cloud motion vectors in real-time • Generates insolation forecast map with error bars L. Hager

  7. Primary Use Case • Power Engineer seeks to use the final GUI application to make smart decisions about how the power company will generate power in the near future. • Engineer may also want to look back on past predictions to compare with actual solar statistics. T. Furlong

  9. Functional Decomposition Level 0 T. Furlong

  10. Functional Decomposition: Level 1 T. Furlong

  11. Level 2 Sub-System: Remote Sensor A. Fruge

  12. Level 2 Sub-System: On-Grid PV Sensor A. Fruge

  13. Level 2 Sub-System: Server User inputs, then GUIdisplays to user Image Processor: Determines cloud motion vectors and sends to forecaster GUI: Receives user input and displays appropriate forecast map Inputs cloud images Receives Data Network: Receives data from sensors and inputs to appropriate location Cloud images Inputs motion vectors Inputs forecasting map Forecaster: Creates forecast map every minute, using data received and updates database Residential power measurements Map Creator: Receives forecasting data and outputs forecasting map to GUI Inputs power measurements Inputs forecast data Database: Saves forecast map and inputs appropriate forecast data to map creator Inputs forecast data Inputs requested map data C. Duclos

  15. Risks and Contingencies • Due to lack of sunlight, Remote Sensor may lose power. • Battery is chosen to be large enough to power the sensor for up to 4 days with no sunlight. • Due to lack of network coverage, data from Remote Sensor may not be transmitted in real time or at all. • Program will be able to compensate for an incomplete data set through the error calculations. M. Dickerson

  16. Risks and Contingencies Continued • Camera lens may have obstructions preventing pictures from obtaining accurate cloud data. • Software will be able to tell the difference between obstructions and clouds. • Protective casing will mitigate the amount of debris that will be able to cover the lens. • Direct sunlight may cause CCD array to be burned, and therefore lose image quality or create “blind spots” on images. • Protective lens filter will ensure minimal damage to the CCD array.
