By the end of the decade, China wind power grid capacity of President million kilowatts, five consecutive years to achieve double. Experts say, with China’s wind power and pv renewable energy sources such as rapid rise, supporting the installed power construction and load of power grid construction must keep up with, but may bring power grid comprehensive operation cost of ascension.

SGC energy research institute vice dean relation introduction said that China has serious wind turbines station scale big and small, power grid capacity construction level weak problem. Wind unstable for grid operation and power supply of economy brings huge challenge.

Support for wind power development and wide range XiaoNa that SGCC increase power grid construction dynamics, by the end of the decade have invested 41.8 billion yuan, wind power grid lines built into 2.32 million kilometers, its business area wind power grid installed has reached 2826 million kilowatts, accounts for the largest hyper electrical load by 4.2 percent.

Among them, MengDong, jilin, hebei north wind ZhuangJiLiang ranked the top three areas, wind power grid capacity of hyper largest load proportion of 82%, respectively 28.6 percent, 9.8 per cent. But for these regional power grid operation is concerned, wind power generators of higher installed bring run unstable factors are increasing.

Experts say, wind turbine generator grid installed the quick increase, it is urgent to quicken the load of power construction, such as pumped-storage power station construction, fuel and gas power station construction, these power output is more agile, timely adjust to grid can ensure stable load demand, but economy poorer.

Relation with advice, should realize the wind channel coal base sinotrans combined foreign send fire, and this helps to expand the wind XiaoNa scope and scale, reduce the large scale wind development costs.

But she also pointed out that in order to adapt to the large scale small wind generators other renewable energy development, power grid comprehensive operation cost would considerably increase. Forecasts of wind power of 2020 targets will be installed from 1 billion kw increased to 150 million kilowatts. Under this circumstance, the grid investment needs corresponding increase 4.8 percent, pumped storage, gas power to improve system load and operation flexibility power investment needs to be increased 8.5 percent and 11.4%, of the whole power system operation cost will improve 1.1%, may push the high price.
