In 2013, the installed capacity of new energy in Gansu Province exceeded 10 million kilowatts, and the installed capacity of photovoltaic and wind power reached 4,298,400 kilowatts and 7,08,100 kilowatts respectively, ranking the first and third places in the country.
Gansu Hexi Corridor is rich in wind resources. Most of the areas are in solar-enriched resources and rich areas. Gansu has a unique advantage in developing new energy. In 2013, Gansu hydropower, wind power, photovoltaic and other renewable energy installed capacity of 19.11 million kilowatts, the province's total installed capacity reached 34.73 million kilowatts, renewable energy accounted for 55.02% of the total installed capacity of Gansu power grid, the province's renewable energy installed capacity accounted for more than half To make strong support for the ecological civilization construction of Gansu.
In recent years, with the rapid development of wind power and photovoltaic power generation in Hexi area of Gansu Province, the energy structure of Gansu power system has undergone qualitative changes. From the simple power supply structure of the original water and fire, it has gradually evolved to be based on large thermal power and large hydropower. Large wind power and large photovoltaics have sprung up, and small hydropower is a complementary multi-power structure. At the same time, the State Grid Gansu Provincial Electric Power Company increased support for new energy development, standardized service procedures such as simplified program review and power grid connection, improved service quality and efficiency, and established a full chain management and control mechanism for grid-connected services of distributed generation projects.
In 2013, the clean and renewable power generation in Gansu Province reached 46.054 billion kWh, an increase of 11.3% year-on-year, accounting for 39.9% of the total power generation in Gansu Province and 44.6% of the province's social electricity consumption. Among them, hydropower generation reached 32.556 billion kwh, up 2.07% year-on-year; wind power generation reached 11.918 billion kwh, up 26.80% year-on-year; photovoltaic power generation reached 1.895 billion kwh, up 510.15% year-on-year.
In order to adapt to the development of power supply, the State Grid Gansu Provincial Electric Power Company actively promoted the construction of a strong smart grid and helped the new energy to operate in parallel. The company actively carried out low voltage traversal, power quality and active and reactive power testing of wind and photovoltaic units, as well as centralized grid-connected testing before PV price adjustment. At the same time, the new energy detection mechanism that is compatible with the requirements of the National Energy Administration has been improved. In 2013, the company also built the first wind power forecasting system based on three sets of data sources in China, and the service new energy development has reached a new level. By the end of 2013, the company had completed a total of 31 low-voltage ride-through capability tests for wind farms, and all 43 test fans passed the test. The safety of Gansu Power Grid and even the Northwest Power Grid was further improved.
As the world's largest wind power base, Jiuquan Wind Power Base faces the problems of transportation capacity, frequency regulation and peaking, power consumption and system stability, which directly affects the development of local new energy. Gansu Electric Power Company fully utilizes its own technological advantages, actively cooperates with the national renewable energy quota system management method, improves the ability of the power grid to optimize the allocation of new energy resources nationwide, and guides the energy-consuming industry to shift to the energy-rich areas in the northwest. The company overcame the major problems highlighted by the integration of new energy sources, fully utilized the role of large-scale resource allocation in the power grid, actively explored the delivery market, increased the cross-regional power delivery work, and strived to turn the province's affluent wind and solar energy into High quality electric energy is exported to all parts of the country. In 2013, the company's external power supply was 12.786 billion kWh, which played a positive role in accelerating the nationwide consumption of new energy in Gansu Province.
In order to further absorb new energy in a wider range of the country, Gansu Electric Power Company is strengthening its report on the development of local new energy, and actively strives to accelerate the preliminary work, ±800 kV Jiuquan - Hunan UHV DC Project Obtaining roads will provide stronger grid support for new energy delivery.
