An increasing share of wind power in China adds to the challenge of integrating renewables into the Chinese electricity grid. Danish experiences transferred through China National Renewable Energy Centre.
China has in recent years installed and connected wind turbines corresponding to 31,000 MW in order to meet its target of 15% non-fossil energy by 2020. This development has made the Chinese market the world’s largest, constituting around 26% of the entire global wind market.
With such a rate of wind power integration, a challenging task arises because the Chinese electricity grid is unable to handle the fluctuating amount of energy from renewable sources such as wind. As a consequence, around 20% of Chinese wind power production was lost in 2012 because wind turbines were brought to halt in periods with much wind and little demand for electricity. The amount lost corresponds to more than 50% of the annual Danish generation of electricity.
Transferring Danish knowledge
To transfer Danish experiences within flexible power production, experts from the Danish Energy Agency have met with local Chinese energy authorities, local power plants, wind turbine owners and representatives for the Chinese State Grid.
The Danish experts will contribute with experience and lessons-learned and Chinese experts will visit Danish companies to a gain better insight into how wind power is used in Denmark in practice.
About the Danish-Chinese cooperation on energy
The cooperation between CNREC and DEA runs to the end of 2014 and will among others focus on:
• The making of scenario analysis and technology catalogue
• Power markets and integration of renewable energy
• District heating and integration of renewable energy
• Road maps for solar power, biomass and biogas
• Research and technical development of 12 renewable energy projects
DEA has gathered a team of experts within the above mentioned fields who will contribute to communicate the Danish knowledge and experience in order for it to be applied in a Chinese context.
