When the generator is generating electricity, if no electrical appliances are using electricity, where does the generated electricity go? Will it be wasted?

Let me start with the big conclusion. At present, there is no large-scale storage capacity, that is, if too much electricity is sent out, it can only be wasted or damaged electric equipment.

But in fact this situation does not happen.

Why do you say that?

To believe in the strength of China's State Grid and China Southern Power Grid, you have heard the words "long-distance ultra-high voltage transmission" and "national grid connection", but this is really useful.

The worst case is that if the power generation is greater than the power consumption, all the electrical equipment in use at this time will share all the power generation. As a result, the grid voltage increases and the power consumption of a single electrical equipment increases. After a certain range, if the power plant does not actively reduce the power generation, some electrical equipment may be damaged.

But such a bad situation rarely happens in reality.

Thanks to the intelligent monitoring system of today's power grid.

First of all, the power grid has been running for so many years, and there are big data, such as the power consumption in various time periods, the power consumption in various seasons and various time periods, with such a huge amount of data, the grid operation will basically be scheduled very appropriately. How to generate electricity, how much electricity is generated is not blind, there are plans.

Secondly, now the power grids are all connected across the country, so electricity consumption can be monitored from time to time, and there can be no significant waste. In special circumstances, it can also be exported to places where electricity is urgently needed. At this time, the role of national networking and long-distance power transmission is reflected.

Furthermore, the power supply can also be adjusted according to the real-time power consumption, such as reducing generator sets and so on. In short, it is very difficult for you to envisage a waste of electricity.

But sometimes it is possible that the power supply is insufficient, mainly due to peak electricity consumption. For example, when air-conditioning is used in large quantities in summer, industrial electricity plus residential electricity exceeds the maximum local electricity supply, so thermal power and hydropower are all used. When there is no surplus power to deploy in other places, the power supply may be insufficient. Then we have to use peak-shifting electricity. After that, it is mainly to ensure that residents use electricity, and the factory may stop production due to power outages.
