The UAE solar Atlas

  1. 1. Dr. Hosni Ghedira, Center Director The Research Center for Renewable Energy Mapping and Assessment at Masdar Institute IRENA-KISR joint workshop on renewable energy in the GCC KISR, Kuwait June 10th, 2013
  2. 2. Vision The Research Center for Renewable Energy Mapping and Assessment aims to develop regional knowledge and leadership in renewable energy assessment and mapping for the Arabian Peninsula and countries with similar climate (mainly in Africa). To become a pivotal hub for advancing research and innovation in tackling the challenge of estimating solar potential for arid and dusty environments.
  3. 3. Key skills: • Satellite data management and processing • Solar radiation modelling • Ground data analysis, data mining and quality control • High performance computing • Machine learning and statistical modelling • Solar irradiance measurements • Real-time remote sensing • Software development and programming • Solar technology assessment • GIS and Map-server development • Artificial intelligence • Climatology and Atmospheric Science 3x Faculty Members 8x Postdoctoral Researchers 5x Research Engineers 8x Research Assistants 2x Visiting Scientists
  4. 4. • Receiving the mandate from the UAE Government to develop the UAE solar atlas. The atlas was successfully launched in June 2012 at Rio+20 Conference in Rio de Janeiro. • After two years of operation, the Center has succeeded to gain international recognition as a pivotal hub for advancing research and innovation in tackling the challenge of estimating solar potential for arid and dusty environments. • The Center has succeeded in developing regional knowledge and leadership in renewable energy assessment and mapping for the Arabian Peninsula and countries with similar climate. Key Milestones
  5. 5. • Playing a key role in the Global Solar and Wind Atlas initiative. The Center is one of the co-developers of the Global Atlas application (with NREL, DLR and ParisTech). • Hosting the Global Atlas Application at Masdar Institute Data Center. The Global atlas servers are presently hosted at our Data Center; operated and maintained by the Center engineers. • Developing and setting up a first-of-a-kind real time solar mapping tool producing solar maps at 15-min intervals. • Starting two new flagship projects: (1) Solar resource forecasting and (2) solar technology simulation in desert environment Key Milestones

  18. 18. Performance Modeling of Solar Power Systems
  19. 19. Technical Performance Modeling Solar Power Technology Assessment Assessment of solar energy potential is the primary application of the UAE Solar Atlas. Objectives:  Performance modelling of solar power technologies  Simulation and integration in the atlas  Assessment of the economic potential
  20. 20. Technical Performance Modeling Design of technical performance models for mainstream commercial PV and CSP technologies with spatial and technological parameters as input variables
  21. 21. Economic Potential Assessment Economic assessment based on the technical performance simulation Additional parameters: Spatial variables Technological variables • Land acquisition cost • Grid infrastructure cost • Road infrastructure cost • Power demand • Land preparation cost • Transportation cost • Capital cost • Installation cost • Operation and maintenance cost • Maintenance time • Operating life • Integrated CSP storage cost
  22. 22. Simulation • Optimum tilt layers (PV) • Design variation layers – mounting tilt (PV) – tracking option (PV) – array to inverter ratio (PV) – solar multiple (CSP) – storage capacity (CSP) • Performance indicator layers – energy output [kWh] – specific yield [kWh/kWp] – capacity factor [%] – performance ratio [%]
  23. 23. Effect of desert-induced soiling on DNI sensor • Dew data was retrieved from leaf wetness sensor (LWS) installed at Masdar Field Station, Masdar City for a year to study seasonal trend • Solar zenith angles of ≤90° represent day-light period • It can be inferred that dew condensation begins at night but continues until few hours after sunrise esp. from as early as October to as late as March.
  24. 24. Effect of desert-induced soiling on DNI sensor Design Limitations:  Absence of ventilation  Rain-shield locks the dust  It also partially prevents exposure to wind for quick dew evaporation  Surface area to sensor ratio: only a few dew drops cover entire sensor glass pane significantly affecting transmittance
