First of allAC powercannot be stored, so the power from the power plant can be used immediately. However, the relationship between the power plant and the user is not as much as it is generated but as much as it is used. Just use as much as you need, there is no waste.
There are two points that need to be stated here. First, it is a fact that electric energy is wasted. How to explain it? Doesn’t it mean that as much as it is used, it is generated? So when there are fewer users, the unit must either adjust For small loads, when the minimum load cannot be maintained, it will be shut down. Therefore, for wind power, solar power, etc., when there is wind and sun but there is no load gap, either the generator or the solar panel must be disconnected. This is Everyone talks about giving up the wind and light.
Hydropower has no load during the rainy season. At the same time, when the water level of the dam is close to the high level, the gate will be opened directly to release water, resulting in water abandonment. This is what we call abandoning wind, light and water in energy waste. The corresponding solution is to give priority to clean energy first, let thermal power units adjust peaks, or build pumped storage power stations, use excess wind power and photovoltaic power to pump water from the bottom of the dam to the top of the dam, and then release the water to generate electricity when there is a shortage of power at the peak. .
These are what we are talking about to solve the waste of clean energy and balance the operation of the power grid through peak shaving and valley filling, and energy storage. The second point I want to talk about is why it can be achieved as much as it is used. In fact, this is the benefit of running a large power grid. The load throughput of the power grid is large. For example, if you suddenly turn on the hair dryer at home, the load of 1 kilowatt will have no impact compared to the load throughput of several million kilowatts of the municipal power grid.
It does not affect it at all, but the peak power consumption in the morning and the peak power consumption in the evening should have been more obvious in the early years. That is, the lights during the peak power consumption are not as good as usual. This is because the peak power consumption has caused aggravation to the power grid. The impact causes the voltage to drop. At this time, the generator set needs to continuously supplement the load. The opposite is true for voltage overvoltage.
So the large power grid can generate as much electricity as it uses, which will increase the throughput of the provincial network and ensure the stability and safety of everyone's electricity consumption. Some people may also say that large industrial power consumers have little impact on the power grid, such as refining furnaces in smelting plants. For such high-power starting appliances, those with more than a few hundred kilowatts will have starting procedures.
According to the power frequency conversion start, the process time from 0-100 is enough to compensate the power grid for throughput. Therefore, the above two points should be able to answer the question of why the electricity is generated as much as it is used without wasting it.
