Is power rationing really due to insufficient electricity?

Some people cannot help but ask, with the development of the economy and the improvement of power facilities, it has been almost ten years since there was a sudden power outage in summer. But why did the phenomenon of "power outages" occur again in 2020, even in winter? What are the consequences if there is no power restriction?All of this starts with the particularity of electricity.

Electricity, a special 'commodity'

Firstly, it should be understood that the beginning is determined by the particularity of electricity as a commodity. People will establish warehouses during the harvest season to store excess food for winter and spring use.However, there is still no mature and stable technological solution for large-scale storage of electrical energy.If the power generation exceeds the demand of society and cannot be stored in a timely manner, the electricity that cannot be generated will be converted into the kinetic energy of the rotor in the generator, and the generator will rotate faster. This not only easily leads to accidents with the generator, but also increases the frequency of alternating current in the power grid, directly causing abnormalities in the machinery and equipment on the production line of the electricity consuming enterprise. Therefore, this determinesElectricity almost needs to be generated and used immediatelyIn this context, a problem arises. The problem is,The adjustment of power generation by energy companies always lags behind changes in electricity consumption.For example, people's spontaneous actions such as turning on and off lights, turning on electric kettles to boil water, etc. are all full of randomness. And it is also impossible for people to notify the power plant when using electricity. Therefore, how to accurately predict the future electricity consumption and use it to determine the amount of electricity generated is a key issue for relevant departments.http://www.zbwf.net
