CL- Windcon is an EU H2020 project coordinated by CENER and with a duration of 3 years, in which a consortium of 15 industrial partners and research centers from 6 European countries, many of them members of the EERA (The European Energy Research Alliance).
Current practice in wind turbines operation is that every turbine has its own controller that optimizes its own performance in terms of energy capture and loading. This way of operating wind farms means that each wind turbine operates based only on the available information on its own measurements. This gets the wind farm to operate in a non-optimum way, since wind turbines are not operating as players of a major system.
The major reasons for this non-optimum approach of wind farms operation are based on the lack of knowledge and tools which can model the dynamics of the flow inside the wind farm, how wind turbines modifies this flow, and how the wind turbines are affected by the perturbed flow. In addition, this lack of tools deals to also a lack of advanced control solutions, because there are not any available tool which can help on developing and testing virtually advanced control concepts for wind farms.
CL-WINDCON will bring up with new innovative solutions based on wind farm open and closed loop advanced control algorithms which will enable to treat the entire wind farm as a unique integrated optimization problem. This will be possible thanks to the development of appropriate dynamic tools for wind farm simulation, at a reasonable computing effort. These tools for wind farm dynamic modelling of wind farm models will be fully open source at the end of the project, while control algorithms will be extensively validated through simulations, and at wind tunnel tests. Some open loop validations will be performed at wind farm level tests.
The proposed control algorithms are useful for future but also for already existing wind farms. Then these will improve the LCOE, as well as the O&M costs will decrease, and improves in terms of reliability of the wind turbine and wind farm will be obtained. These performance improvements will be evaluated for both, wind turbine operation and wind farm operation.
CENER coordinates the project. Similarly, from a technical point of view it contributes to the following tasks:
- Development and comparison of wind farm models for the design of park controllers with multiple levels of fidelity and complexity.
- Development of wind turbine control strategies in order to modify the behavior of the wake: induction control and wake redirection control.
- Development of wind farm control strategies in order to optimize total energy production by reducing mechanical loads. Integration of multiple control technologies in a single optimization protocol.
- Evaluation and validation through high fidelity simulations (CFD), wind tunnel tests and field tests in order to validate both advanced engineering models and park control strategies
- Feasibility study of wind turbines and wind farms re-design using the new holistic approach (considering the wind farm as a whole)
- Economic evaluation of integrated advanced control strategies, applying life cycle cost calculations and life cycle evaluation.
CENER also leads the block of activities of exploitation, dissemination and communication of results.
