Control in Wind Turbines

Control is the intelligent component of a wind turbine, and largely responsible for the reduction of the LCOE, thanks to the direct impact it has on the cost of its structural components, as well as on the amount of energy it produces. CENER has extensive experience in the development, design and commissioning of the wind turbine control system, having even implemented our controller in commercial turbines that were located on three continents. Having a control solution for terrestrial and marine wind turbines, the domain of this virtual component of the wind turbine is key for the development of terrestrial and marine wind technology, as well as to understand and improve the operation of wind turbines and wind farms.

 Control in Wind Farms

Management and operation of the wind farms is a technology still in development, which aims to operate the wind farm as a single integral system, compared to the traditional vision that opts to operate the machines independently. In order to develop this and other technologies, it is necessary to study and analyze the behavior of the wind turbine. It is therefore essential to have a thorough knowledge of the control of the machine, among other things, in addition to an understanding of how a wind turbine performs and suffers the consequences caused by changes in its operation, etc. Solving these issues is only possible through aeroelastic models such as those used by manufacturers to design their high power wind turbines. CENER has developed the technology to be able to reproduce these models, with which it is possible to predict with great precision the production and mechanical loads that the turbine has suffered in the past and will suffer in the future.

The conjunction of the dynamic behavior, through its control and numerical model, allows to increase the performance of a wind farm thanks to the management and control solutions, allowing to increase its production as a single system, while It makes it possible to extend the life of the wind turbines that compose it without losing production in the parks. This knowledge is therefore very useful for the manager of a park, since it provides a considerable economic and time saving when planning the exploitation strategy of the machines of a wind farm.

The development of the control of the park has an important milestone through the project EU H2020 CL-WINDCON, led by CENER, in which the researchers of our Department of Wind Energy are developing a holistic control of the park, which prioritizes the optimization of its production total compared to those that occur individually in each of the turbines.

Energy Management System

Microgrids are power generation systems that allow the distribution of electricity to consumers or loads, using digital technology and favoring the integration of renewable sources of generation, with the objective of saving energy, reducing costs and increasing supply reliability.

Those responsible for carrying out this intelligent energy management are called Energy Management Systems (EMS).

CENER has designed its own EMS, based on a hardware platform type HMI (Human Machine Interface), consisting of an industrial PC with a touch screen.

The HMI provides innovative solutions not only to the initial configuration and start-up of a microgrid, but also to its control and management during the period of operation. The HMI integrates its own SCADA system, or it can be compatible with an existing one for the control of the elements that make up the micro network. Also, its software integrates two levels or additional modules:

  1. Energy management and optimization module. This module includes operation management strategies; that is to say, how to fulfill the objectives or functionalities that are requested and, consequently, it optimizes the state of load of the storage systems during a certain period.


  1. Module of communication, management and storage of data, errors and alarms. The HMI of CENER has been validated in highly complex projects, with different technologies of renewable generation, fossil generation and storage systems, and is available for the sector associated with various service levels.
