Industry Perspective Preview: R&D gaps for off-grid power - time to think big about going small Industry Perspective Preview: R&D gaps for off-grid power - time to think big about going small

A major drive to bring renewable energy to the 'electricity poor' is underway, but despite the progress made so far, under a business-as-usual scenario around 600 million people will still not have access to electricity by 2040, according to the International Renewable Energy Agency (IRENA).

Research Focus: Enhance variable speed wind turbine transient performance – and make obsolete wind turbines last longer Research Focus: Enhance variable speed wind turbine transient performance – and make obsolete wind turbines last longer

The demand for wind power is on the rise, and it is becoming increasingly important to take the stability of wind farms into account - to ensure safe and efficient delivery of power. According to recent grid requirements, wind farms must adapt to transient disturbances as quickly as possible, while keeping grid-connected wind farms operational during disturbances in the power network. This study analyses various control strategies that enhance variable speed wind turbine transient performance.
