China aims for 90 Gw of wind power
The government also intends to find technologically feasible and economically reasonable solutions to accommodate the clean but unstable electricity production from 150 GW of wind power farms by 2020.
China’s installed wind power capacity has been doubling annually in the past four years to around 25 GW at the end of 2009, with the majority built in inland regions where wind power is rich but power demand is relatively small.
However, effective wind capacity is smaller. Some wind power farms ground to a halt as local grid capacity could not take up a rising number of intermittent energy sources while some others stood idle from day one due to the lack of grid access.
The regional grid in northeastern China, for example, can provide grid connection for 9.2 GW of wind power capacity this year, but a total of 13.2 GW of wind power mills are expected to be installed throughout the year, according to an official with local power industry watchdog.
The largest constraint to large-scale wind power development is the lack of sufficient grid connection, Liu Qi, deputy head of the energy administration, was quoted as saying in a report published on Tuesday on the website of the National Development and Reform Commission (www.ndrc.gov.cn).
The NEA will organize six months of research to focus on wind power planning, market development and power transmission in 11 provinces and regions to coordinate wind power and grid development, Liu said.
Shi Lishan, vice director of the renewable energy department under NEA said last Friday that there were no technology problems in terms of grid access and it involved the balance of economic interests. – Reuters
Problem of wind variations and generation will be the prblem in future where the wind farms are more dense. However in india it is not so sofar. Wind farm instalation is hardly 10% of total installations.The above your article reveals China is going in a bigway without thinking of generation variation from wind farms. A technology should be developed to balance the variation of generation from wind with hydel stations, So that any increase in wind generation should indicate to hydel stations to decrease its generation as soon as possible to avoid grid variations. But this is quite challenging in case of Thermal generation, as the generation control and fuel management is again another chalenge in these thermal power stations. In india we should develop this technlogy now itself as we are still in the first quarter of wind generation contribution.
