Some provinces, such as Guangdong, Hunan, Anhui and other places, are mainly short of electricity supply, and enterprises are forced to peak-shift and limit electricity. In some provinces where power cuts occur, some are affected by both energy consumption control and power supply shortage.
Northeast power rationing has nothing to do with dual control, but is caused by power shortage. Generally speaking, power shortage first affects industrial and commercial power consumption, and measures should be taken to use electricity in an orderly manner. Residential electricity consumption is the focus of the government and the power sector. Recently, the northeast suddenly lost power and residents used electricity.
In case of power failure, the power grid dispatching department will directly cut off the 10 kV voltage line according to the preset switching sequence table. 10 kV lines are usually connected to industrial and commercial loads as well as residential loads. So residents will suddenly lose power without notice.
The power outage caused by power grid operation risk is the direct cause of residents' unexpected power outage, but if the normal operation process is followed, the power shortage accident should not be so serious. For example, in Guangdong, which is also short of electricity, the continuous peak load has exceeded 20 million kilowatts recently, and there has been no temporary power cut by residents.
The power cut in the northeast eventually affected residents, and there are deeper reasons. Specifically, the increase in the proportion of new energy has also increased the risks faced by the power system, and the orderly use of electricity has not been well implemented.
