Vestas Is Testing Solar & Wind Hybrid System In Spain

In Clean Facts, Clean News, News, Renewable Energy, Solar, Technology, Wind

The renewable energy companies Vestas and Energias de Portugal Renováveis (EDPR) describe a hybrid demonstration setup based on wind and solar photovoltaics to be installed at an EDPR wind farm in Cádiz, Spain.

An array of 372 kW of solar photovoltaics will be coupled to an existing Vestas V112-3.0 MW turbine. The PV power is fed to the turbine as direct current, which is then converted and transformed by a modified power conversion system inside the turbine before the power is exported to the grid.

This setup is expected to increase the overall capacity factor and annual energy production.

For the project, Vestas has upgraded the technical specifications of the turbine’s controllers, converters and design as well as installed new hardware. By connecting wind and solar through the turbine’s power electronics and utilising its full-scale converter, the number of converters is reduced, contributing to lower equipment costs and thus cost of energy.

This is a very smart move in order to get more knowledge on how to improve on the problem of intermittency in renewables. It will be interesting to see whether this approach of mixing wind and solar at the facility itself will further reduce the need for battery storage.

The lesser the intermittency the lesser storage capacity is needed to even out the last bumps to secure a stable supply of electricity to the consumer.
