Wind power and protecting the network sent out a smooth process, the driving force of science and technology can not be ignored.

Acceptance of wind power capacity of healthy and orderly development of wind power guidance. Wind Power is the proportion of total generating capacity of wind power system, the ratio of peak load area. To offset the intermittent nature of wind power generation on the impact of wind  power generation and supply balance, the other power grid must also meet the rapidly changing load and has sufficient capacity and speed regulation. Hebei region as high as 98% coal-fired units, power conditioning inadequate capacity to regulate the speed difference, the power imbalance in the structure of the proportion of restricting access to the largest wind power factors. According to China’s Beijing-Tianjin-Tangshan Power EPRI acceptance of wind power capacity, ensure the system reserve capacity in the case of peaking units running full capacity to ensure maximum access to wind power.

Wind power output of wind power forecasting system to improve operational control level. Accurate forecasts of wind power can be adjusted to reduce the reserve capacity of the system needs to ensure balance of power fluctuations of wind power to reduce the reserve capacity and economic operation will play an important role. Power output of wind power forecasting system using numerical weather prediction wind generators output, optimize conventional generating unit scheduling and real-time scheduling to solve the wind power output as random and intermittent problems caused by the power peaking frequency can effectively avoid “abandoning the wind “and raise efficiency of resource use wind energy.

Power Line Series Compensation sent enhance the capacity of power lines. Installation of power lines through the series compensation device, which can shorten the lines of the electrical distance, thereby enhancing the ability to send line.

By deepening the research and application of science and technology to protect the power grid security, stability, reliable operation, which effectively increases the efficiency of wind turbines sent out, a large-scale wind power to meet the needs of rapid development. Currently, the Zhangjiakou region wind power capacity reached 220 million kilowatts, has become China’s wind power capacity of the largest prefecture-level city. 2020, Zhangjiakou region the total installed capacity of wind power will reach 10 million kilowatts, and promote healthy and orderly development of wind power, but also need special attention and resolve the following key issues:

First, to achieve a wider range of optimal allocation of resources. Northwest and north away from the wind-rich region of most of the load center, power consumptive inadequate, further study long-distance, large-scale transmission technology, high voltage power grid through a greater range in the east, and so the allocation of resources to improve the transmission efficiency .

Second is to improve the efficiency of wind power transmission network. On the one hand, large-capacity storage technology to speed up research, large-scale wind power base in the appropriate size of the storage building or a pumped storage plant, will be adjusted to balance the uneven power delivery and reduce transmission costs. On the other hand, according to the different situations in different regions, considering the development of wind – water, wind – fire, even the wind – light strapping joint delivery, dedicated delivery channel to improve the wind power utilization.

Third, characteristics of wind turbine attaches great importance to the research and testing. Establishment of wind turbine research, testing, testing a unified platform, standard type of wind turbine products, certification and network testing, network testing for wind power implementation of the system to provide effective technical support.

Fourth, supporting projects to implement renewable energy financing and policy support. Supporting large-scale wind power grid connection of large-scale wind power project-specific investment, crowding out investment in the project conventional power grid space, return on investment in the current grid system works under the premise of uncertainty, may affect the healthy development of the enterprise network, needs the state to give funding and policy tilt.
