- The UK government aims to increase renewable energy provision into the
into the UK national electricity grid. They have a target of 15% electrical
energy by 2015 and an aspiration of 20% by 2020
- Wind is an uncontrolled energy resource, it blows when it wants.
- Integrating this level of wind into a highly controlled grid system brings new
- EoN Netz in Germany and Avista Utilities in California have both declared
that managing power variations from wind is problematic
- This study has assessed the impact 25 GW of wind will have on the grid.
This represents 16% of energy at a Capacity Factor of 30%
- In particular the power variations of a distributed wind fleet is assessed and
found to be highly volatile, combining large magnitudes of power fluctuation and high rates of change
- To balance the grid, other generators will be required to vary output, reducing the opportunity for other renewable generators to supply electricity
