New electricity connected to Inner Mongolia's energy grid increased by more than 25%. According to the request for relevant public information: Inner Mongolia has accelerated the adjustment of the power grid structure and attached great importance to the installation and construction of wind, solar and biomass power grid connections . Annual electricity production from new energy sources such as. wind power, solar power and biomass reached 22.944 billion kilowatt hours, an annual increase of 25.59%. Electricity generated on the grid was 22.494 billion kilowatt hours, an annual increase of 25.49%, both reaching records.
The importance of expressing the capacity coefficient of wind energy
The development of wind turbines has been too rapid and has had a great impact on the electricity grid. The switch to low voltage hasbeen almost transformed. Once the AVC transformation is completed, the response of the power grid will be improved. I think the large-scale power rationing you mentioned is not a deliberate restriction on the part of the power grid. This depends on the capacity of the local wind farm's grid connection point. Your grid connection point is 220 kV or 110 kV, and the capacity cannot exceed 100 kV. while wind farms in Northeast China and Inner Mongolia. The large one can reach 400,000 and the medium one can reach 200,000. The electricity consumption in the Northeast and Inner Mongolia is not so large when it is initially designed. , the trend of developing new energy is a national policy. The power grid can deploy wind farms, but it must comply with national policies. In response to the development trend, wind farms have been built in larged number, but the electricity network was not followed. or transformed in advance, leading to widespread energy rationing. At present, if the wind farm is built near a 500kV main station, there will be almost no power rationing, that is, it will almost be the Spring Festival , because you cannot influence it, and your total or zero production will have almost no impact on its voltage. I suggest you report this to your superiors. The location of the post is very important. Avoid the ends of these lines and be close to the main station! Moreover, smart grids will come and the bread will come.
The ratio of the total electricity production of a wind farm over a certain period divided by the product of the number of hours during that period and the installed capacity of the power plant. (Expressed as a percentage)
Taking a certain month as an example, a select groupectrogen with a gross capacity of 300 MW generates 120 million kilowatt hours, has an operating time of 436 hours and the monthly statistical duration is 720 hours, then The equivalent operating hours in gross capacity are:
(12000÷436)/30×436=400 (hours)
The gross capacity coefficient is:
400/720*100=55.56
The ratio between the hours of actual annual use of the wind farm and the number of hours throughout the year, or the ratio between the actual annual network of the wind farm. electricity connected to the nominal annual electricity connected to the grid. (Expressed as a percentage)
