First of allAC powercannot be stored, so the energy from the power plant can be used immediately. However, the relationship between the power plant and the user is not smooth. as much as it is generated but as much as it is used, use as much as you need, there is no waste.
There are two points that need to be emphasized here. First, it is a fact that electrical energy is wasted. How to explain it? used, it is generated? So when there are fewer users, the unit either needs to adjust the 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 difference, either the generator or the solar panel must be disconnected. Everyone is talking about abandoning the wind and the light.
The hydroelectricity has no charge during the rainy season. At the same time, when the water level of the dam is close to the high level, the valve will open directly to release the water, resulting in water abandonment. This is what we call abandoning wind, light and water in energy waste. The corresponding solution is to prioritize clean energy first, let thermal power plants adjust peaks or build pumped-storage power plants, use excess wind and photovoltaic power to pump the water from the bottom of the dam to the top of the dam, and then release the water to generate electricity in case of electricity shortage at peak.
This is what we're talking about to solve clean energy waste and balance the operation of the power grid through peak shaving, valley filling and energy storage. The second point I want to talk aboutThis is why it is possible to take as many shots as you use. In fact, that's the benefit of running a large power grid. The load flow of the electricity network is important. For example, if you suddenly turn on the hair dryer at home, the 1 kilowatt load will have no impact compared to the load. multi-million kilowatt load rate of the municipal electricity grid.
This doesn't 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, i.e. the lights during maximum power. Power consumption is not as good as usual, because the peak power consumption has caused the power grid to worsen. At that time, the generator needs to supplement the charge continuously. voltage surge.
Thus, the large electricity network can produce autant of electricity it consumes, which will increase the flow of the provincial network and ensure the stability and security of everyone's electricity consumption. Some may also argue that large industrial electricity consumers have little impact on the power grid, such as refining furnaces in foundries. For such powerful starting devices, those over a few hundred kilowatts will have starting procedures.
Depending on the start of the electrical frequency conversion, the process time from 0 to 100 is sufficient to compensate for the flow of the electrical network. Therefore, the above two points should be able to answer the question of why electricity is produced as much as it is used without wasting it.
