In search of new solutionsHow to lower barriers for large scale PV plants?
As the penetration of PV increases, improved accuracy and finer spatial and temporal resolution of solar data sets are needed to optimize the performance of these technologies in the energy system of a particular region or country.
We are happy to announce the start of the IEA PVPS Task 16 where an international expert group will research new methods and improve existing ones to increase PV yield and reliability.
International collaboration and consensus on developing and managing these data sets will expedite the high penetration of solar technologies, and improve markets for these technologies.
Large scale PV plants now need accurate resource and forecast data due to high investment costs.
Task participants will focus on the following two scientific issues:High frequency variability and solar forecasts for managing grids with high penetration of PV and local storageHigh quality solar resource assessments and forecasts for solar installations notably in the multi MW class
IEA Task 16 Goals
The main goals of Task 16 are to lower barriers and costs of grid integration of PV and lowering planning and investment costs for PV by enhancing the quality of the forecasts and the resources assessments.
To reach this main goal the Task has the following objectives
- Lowering uncertainty of satellite retrievals and Numerical Weather Prediction (NWP) models for solar resource assessments and nowcasting.
- Define best practices for data fusion of ground, satellite and NWP data (re-analysis) to produce improved datasets, e.g. time series or Typical Meteorological Year (TMY).
- Develop enhanced analysis of long-term inter-annual variability and trends in the solar resource.
Develop and compare methods for- Estimating the spectral and angular distributions of solar radiation (clear and all-sky conditions)
- Describing the spatial and temporal variabilities of the solar resource
- Modelling point to area forecasts
- Probabilistic and variability forecasting
- Contribute to or
setup international benchmark for data sets and for forecast evaluation.
Task 16 Approach
The work programme of the proposed Task 16 addresses on one side scientific meteorological and climatological issues to high penetration and large scale PV in electricity networks, but also includes a strong focus on user needs and for the first time a special dissemination subtask. Dissemination and user interaction is foreseen in many different ways from workshops and webinars to paper and reports.
Evaluation of current and emerging resource assessment methodologies: - Ground based methods (instruments, soiling)
- Numerical weather models (NWP)
- Satellite-based methods (uncertainties, modelling)
- Benchmarking framework
Enhanced data & bankable products: - Data quality & format
- Merging of satellite, NWP and ground data
- Spatio-temporal high variability
- Long-term inter-annual variability
- Products for the end-users
Evaluation of current and emerging solar forecasting techniques: - Value of solar power forecasts
- Regional solar power forecasting
- Variability forecasting and probabilistic forecasting
Dissemination and Outreach: - Task Brochure & Newsletters
- Conference and Journal papers
- Webinars and/or conference presentations
- Connection to the International Solar Energy Society (ISES)
- Workshops (at major conferences)
- Reports
- July 2017- June 2020
- Task16 period of performance:
July 2017- June 2020
The project requires the involvement of key players in solar resource assessment and forecasting at the scientific level (universities and research institutions) and commercial level (companies). A consortium of 51 institutions from 20 countries has been formed. This includes large science centres like DLR, NREL or Fraunhofer, universities like State Univ. of New York, Mines ParisTech and Univ. of Jaen, national weather services like DWD, BOM or DMI and service and data providers like Solargis, Vaisala or Meteotest. The work plan is also focused on work that can only be achieved through international collaboration like the definition and organization of benchmarks or the definition of common uncertainty and variability measures. E.g.
the measure P10/90 years, which is often used today, lacks a commonly accepted definition up to now.
Publications
The Task 16 starts in July 2017 and will go on for three years. Therefore no publications are yet available. The main contribution of the preceding Task IEA SHC 46 was the solar resource handbook (LINK), which is currently updated.
