The biggest hidden danger is the impact on the capacity of the electricity grid. Unlike nuclear power, which can produce electricity stably at the same power 24 hours a day, 365 days a year, the energy produced depends entirely on the wind (in fact, the normal production duration of wind energy is less than 8 hours per day under normal circumstances). This can result in insufficient power supply when the grid is low on power. What is even more troublesome is that when the grid load is low, if the power produced is high, the excess electricity has nowhere to go (electricity cannot be stored) and the grid is forced to increase its load (artificially increase the load to consume electricity, such as increasing resistance, connecting to ground, etc.). This causes fluctuations in the electricity network, exerts strong pressure on the distribution of the electricity networkrisks throughout the region and also endangers the security of the electricity network.
Why is it easy for power grid dispatch to demarcate wind power?
Neither wind power nor thermal power production have the capacity to store electricity. If so, it's in an environment. special industry, because the capacity to store electricity The cost is much higher than the cost of electricity generation, and there is almost no electricity storage capacity in the entire power grid. You must clearly understand the word power grid. a large network. On the one hand, they store electricity. On the other hand, electricity is exported. All power plants (coal, wind, hydro) are on the side of the power grid that receives the electricity. adjust the balance between received power and output power. Generally, the powernce received is adjusted according to the output power, that is, the amount of electricity you produce depends on the amount of electricity you can use.
< p>Wind energy equipment do not have batteries, that is, if the power received in the entire electricity network is less than the power output, the wind farm will do so. The electricity produced is connected to the grid at that time, the electricity produced by. the wind farm is valuable. When demand is low, electricity from the wind farm is disconnected from the grid. The wind power equipment may be idle or the brakes may be stopped and no electricity is generated.< p>Nowadays, it is difficult to solve the problem of connecting wind power generation equipment to the grid, because the electricity they generate is not very stable and has a great impact on the electricity grid. For example, if wind power equipment is connected. to rnetwork to generate electricity, suddenly the wind in the sky increases, the wind power equipment will always remain. If you fail to adjust your own power generation, the wind will increase, the generator will speed up, the power will increase, and the voltage will increase, which will impact the power grid. Just like when you use a light bulb at home, it will be very bright when the voltage is high. It is very dark when she is weak. use 220V household electricity. If the effect on the electricity grid is much greater than the effect of the light bulbs in your house.The reason why the distribution of the electricity network is easy to decoupling wind power is that wind power is unstable. Wind power refers to the production of wind energy, which converts the kinetic energy of wind into electrical energy. However, it is impossible to have wind all the time, wind energyis therefore extremely unstable. Grid dispatch is about stabilizing energy and allowing residents to use it. stable electricity, so grid distribution is easy to resolve. Wind energy is listed because wind energy is unstable.
