Forecasting commercial services from S2M - Juan Liria (Sun2Market)

  1. 1. Sun to Market Solutions14 June 2013Sun to Market Solutions
  2. 2. Sun to Market Solutions was founded in response to the growing need forindependent technical support and engineering services in the solar powersector.14 June 2013Sun to Market Solutions2S2m offices S2m has deep bench of technical expertise with over 25 engineers in five continents. We have performed detailed studies and analysis in over 30 countries in the last five yearsproviding us with one of the best-in-class reputation in the solar sector. Our ongoing collaboration with plant operators give us a unique position in theadvisory/engineering community.

  4. 4. Nowcasting is a short-term and very-short weather forecasting useful forsolar power plants performance optimization and grid integration.14 June 2013Sun to Market SolutionsThe S2m Nowcasting system provides continuous DNI & meteo data streaming forthree forecast horizons: 0 – 15 min (time step of 1 minute) 15 – 45 min (time step of 5 minutes) 45 – 240 min – 24 h (time step of 60minutes)Sky images Satellite images Numerical models4
  5. 5. 14 June 2013Sun to Market SolutionsExample: Puerto RicoPuerto Rico Electric Power AuthorityMinimum Technical Requirements for Photovoltaic Generation (PV) Projects7. RAMP RATE CONTROL:Ramp Rate Control is required to smoothly transitionfrom one output level to another. The PV facility shallbe able to control the rate of change of poweroutput during some circumstances, including but notlimited to:(1) rate of increase of power, (2) rate of decreaseof power, (3) rate of increase of power when acurtailment of power output is released; (4) rate ofdecrease in power when curtailment limit is engaged.A 10 % per minute rate (based on nameplatecapacity) limitation shall be enforced.This limit applies both to the increase and decreaseof power output.5

  7. 7. 14 June 2013Sun to Market Solutions Provides uncertainty factor control in real-time, supporting grid operatordecisions as well as global grid operation strategies. Optimizes battery storage and improves the ramp rate control of CPV andPV power plants. Evaluates operation alternatives in view of equipment breakdowns orunexpected events (Preventive and corrective maintenance) Increases over all efficiency of solar power plantThe final objective of the S2m Nowcasting system is to improve thepredictability of the solar power plant production7
  8. 8. • Facilitates load balancing• Enhanced load prediction for renewableenergy sources• Highly granular view for sensitivetransmission areas• Enhances long term forecasting throughlearning algorithms• Provides assessment window on ramp-upperiod for base-load generation• Increases efficiency in switching costs andback-up powerFor TSOs• Provides detailed forecast on plantoperating conditions• Allows operators to optimize O&Mschedules in line with expectedproduction drops• Enhances accuracy of productionreporting to the ISO/distributor• Provides longer-term data on localweather conditions and patterns• In CSP plants, facilitates the arbitrage ofstorage, natural gas prices, and PPApenalties for optimized dispatch.For Owner/OperatorsBenefits on Both Sides of the T-line
