With the significant development of wind power, it has been inevitable for wind farm cluster to integrate into the system from the grid end, therefore, the power grid loss problem of large-scale wind power integration is highlighted. At first, we construct a power transmission system model with large-scale wind power integration, get the power grid loss calculation formula of the system, and induce the change laws of the power grid loss by the constraints of power transmission channel flow. And then, based on the structure of Gansu power grid, we do some simulations about power grid loss distribution by the constraints of power transmission channel flow, and verify the correctness of theoretical derivation.

As an increasing proportion of wind power in power grid, reactive power problem has become the most important problems in wind power integration. But as a result of wind power is a kind of intermittent energy sources, and put it into use in a large scale only just beginning. Many urgent problems which affect on system stability need to be resolved, such as voltage stability, reactive power compensation. This paper discussed the problems which around the reactive power compensation and angle stability issues while wind power integration.

Wind Power Development

Due to a series of supporting policies in recent years, China wind power has developed rapidly through a large-scale and centralized mode. This paper analyzes the two major concerns faced by China’s wind power development: wind generation reliability and wind energy balancing. More specifically, wind farm tripping-off-grid incidents and wind power curtailment issues, which caused huge economical loss, are investigated in details. Based on operation experience of large wind power bases, technical recommendations and economic incentives are proposed to improve wind power integration and power grid reliability. As a summary and outlook of wind power development in China, this paper provides a reference on future wind power development for other countries.

The Impact

In recent years, wind power penetration into the grid has increased rapidly with abundant wind resources in Jiuquan, according to the policy of the Chinese government to “establish a ‘Hexi Wind Power Corridor’ and rebuild another Western ‘Terrestrial Three Gorges Dam’”. By the end of 2010, the total installed capacity of wind power in Jiuquan has reached 5160 MW. The wind farms are connected to 110 kV transmission network or above in Jiuquan, the studies of their impacts on the grid, in particular, the grid operation are becoming serious and urgent. Jiuquan is far away from the load center with a weak grid configuration, therefore issues such as transmission line overloading, local grid voltage fluctuation, and transient stability limitation are looming with large scale wind power integration. The power system dispatch and operation are influenced by the intermittent nature of the wind power, which should be regulated by the system reserves. This paper discusses the recent integration of wind power into the grid with a focus on the impact on the Gansu power grid operation. The paper also presents the measures to deal with these issues.
