Really. According to the official website of Huainan Shouxian County, the Huainan Shou County Distributed Breeze Power Generation Project is a project that uses natural wind energy to generate electricity. It has the advantages of environmental protection, sustainability, and conservation. By capturing natural wind power and converting it into electricity, it can replace non-renewable energy sources such as fossil fuels and provide people with clean energy. Huainan Shouxian Distributed Breeze Power Generation Project is located in Shouxian Xinqiao Industrial Park, with a total investment of 13.67 billion yuan. The distributed breeze power generation project in Shou County, Huainan is real.
Wind power and photovoltaics are new energy sources that China is focusing on developing, and the power grid must fully absorb them and give priority to their use. Hydropower also requires priority use of the power grid during flood periods. This is a comprehensive consideration of a series of factors such as environmental protection and carbon emission reduction by the state. So there is nothing the power grid can do! Why is it called "junk electricity"? There are mainly two aspects.
First, photovoltaic and wind power have small installed capacity and are scattered, making it difficult to meet the peak load regulation needs of the power grid! To put it simply, when the weather is sunny and the wind blows, the insufficient thermal power will be supplemented. When the short-term demand for electricity increases rapidly, photovoltaic and wind power cannot satisfy it. On cloudy days and when there is no wind, the power plant is dead. When there is a power shortage, thermal power is used! And the price of new energy on-grid electricity is relatively high! This means that when the sun comes up, the thermal power load is reduced, and when the sun goes down, the thermal power load is increased. For the power grid, constant adjustments are required, which is not conducive to the security and economic operation of the power grid. Second, wind power and photovoltaics are not stable enough, causing harmonics to be transmitted back to the power grid system, which will increase power losses and affect motor efficiency, which will affect high-precision manufacturing! These two reasons should be the reason why photovoltaic and wind power are called "waste power".
Both are new energy power generation, which are currently encouraged and vigorously developed by the state, and there are huge state subsidies. , the grid settlement price of thermal power is about 0.3 yuan per kilowatt hour, and the price of wind power and photovoltaic power generation ranges from 0.3 to 0.8 yuan.
Both types of power generation had a fatal flaw at the time, which was their intermittency. Solar power generated electricity during the day and could not generate electricity at night. Wind power could generate electricity when there was wind, but it would not be able to generate electricity when there was no wind. These two types of power generation are actually not welcomed by the power grid, but due to the state's support for new energy and the requirements for energy conservation and emission reduction, the power grid company must accept it unconditionally.
There are more and more of these two types of power generation, which bring instability to the power grid. At present, we mainly rely on thermal power peak shaving, pumped water energy storage, wind power heating, and the construction of energy storage power stations to solve intermittent problems. At the same time, wind and solar power forecasts are becoming more and more accurate, which also reduces the pressure on power grid regulation.
