General Assembly and EC Review held in Brussels, Belgium, from January 31th to February 2nd

By 03/02/2017News

A General Assembly of the PreFlexMS Project was held at the Hotel Metropole in Brussels, Belgium. In the first part of the assembly (on January 31th), each WP leader presented the achievements of the last six months and laid out the upcoming work for the next 3 months.

In the second part of the assembly (on February 1st 2017), the success formula of the previous General Assembly was maintained: break-out sessions were organized by grouping WPs with strong interlinks, to foster discussion, collaboration and provide an occasion to clarify objectives and align strategy.

On February 2nd 2017, the EC review was held in the same Hotel with participants representative of Work Packages leader organizations, as well as several participants related to the WP7 (Demonstration). This is a comprehensive assessment is intended to evaluate in detail the following aspects:

  • The degree to which the work plan has been carried out and whether all deliverables were completed
  • Whether the objectives are still relevant and provide scientific or industrial breakthrough potential
  • How resources were planned and used in relation to the achieved progress (and if their use respected the principles of economy, efficiency and effectiveness
  • The beneficiaries’ contributions and integration within the action
  • The expected potential scientific, technological, economic, competitive and social impact, and plans for using and disseminating results.

As a curiosity, both the PreFlexMS General Assembly and EC review (figure, left) took place in the same meeting rooms as the first Solvay Conference in 1911 (bottom figure, right).

During this period (June 2015-January 2017) we have made significant progress in key areas of the project.

  • Electricity price profile projections have been made based on today’s energy mix and the countries announced renewable energy strategy to estimate the pricing regime in the future.
  • The full power block (based on a once through steam generator) designed for a full scale CSP plant will be quicker, more responsive and more economical to operate with respect to total cost-of-ownership compared to a drum type steam generator, according to the high-resolution dynamic modelling carried out.
  • Weather forecasting infrastructure and digital interfaces with demonstration software architecture have been defined.
  • Novel methods for DNI forecasting and impact of aerosols have been investigated and the validation sites relevant for different CSP use cases have been selected.
  • A virtual power plant model for the CSP plant which incorporates the static and dynamic modelling of the various components has been achieved, that will be used to test the dispatch optimiser as well as the machine learning algorithms.
  • The entire software architecture for collection, management, computation and actuation is also designed and will now be built.
  • The models to be used for weather forecasting and their specifications for optimiser interface have been defined.
  • Based on the performance model, it appears that two strategies for dispatch optimisation would be developed further (dynamic programming based and heuristic)
  • Multiple machine learning algorithm strategies have already been assessed and the most promising ones are to be tested on the software models.

With respect to the demonstration hardware, it is worth to mention the following achievements:

  • The water steam skid (as well as other auxiliary balance of plant equipment) has been designed and is under procurement to allow OTSG to operate in industrially relevant environment.
  • The various engineering studies to safely construct and operate the demonstration have been performed and now the procurement activities are ongoing.
  • The engineering design of the water steam skid, interconnecting piping and OTSG pilot design is also completed.
  • Procurement and construction activities are to follow at the site.
  • A specialised life-cycle assessment tool is used with extensive data collection to obtain important LCA measures. Tool build-up and data collection is ongoing within this task
