How to ensure stable power supply in bad weather?

In the hot summer, the temperature is high and the humidity is high. Many friends cannot live without air conditioners. With the air conditioners running continuously, the electricity consumption in summer will naturally surge. In addition to the high temperature weather, some areas have experienced large-scale rainfall in recent times, which has also brought huge challenges to the power system.

Under the pressure of high temperature weather, how can the power system ensure stable and reliable power? How can the power grid system be intelligently deployed under high load? What else should be paid attention to in terms of safe electricity use in summer?

How does the power system cope with the test of high temperature weather?

Electricity is a special commodity, but like ordinary commodities, it has production, circulation and consumption links. The power system is generally composed of three parts: power plants, power grids and power users. Gui Xu, the main network planning supervisor of Anhui Economic Research Institute of State Grid, introduced that, among them, power plants are equivalent to power producers, mainly responsible for converting energy into electricity; power grids are equivalent to “logistics”, which play the role of power transmission, relying on substations, distribution stations, power lines and corresponding auxiliary control equipment to transmit electricity to power users; power users are also power consumers, referring to power-consuming equipment that consumes electricity. Power users can be large factories or thousands of ordinary residents.

Gui Xu said that under the pressure of high temperature weather, in order to ensure the stability of power consumption at the consumer end, the power system generally carries out planned maintenance of power generation equipment in advance to ensure the normal operation of the equipment. For power plants, it is necessary to ensure a stable energy supply. For example, power plants that rely on fuel power generation should track and monitor fuel inventory to ensure a stable fuel supply; power plants that rely on hydropower generation should have sufficient storage capacity to avoid reducing power generation capacity due to low water levels caused by drought. In terms of power transmission, it is necessary not only to maintain the normal operation of transmission and distribution equipment and ensure a good power transmission state, but also to make various emergency plans to ensure that power can be reasonably allocated in emergency situations.

How much is used, how much is produced?

In summer, the demand for air conditioning is high. How do power plants adjust the power generation according to the production and life of the general public? Gui Xu said that the power consumption at the consumer end can be predicted. The prediction of power demand is an important task of the power system. At present, the working mechanism and prediction method are relatively mature.

Gui Xu added that if the real-time balance between power generation and power consumption is to be maintained, on the one hand, power producers must have the ability to adjust their own power production at any time. For example, since new energy power plants cannot adjust power generation in real time, power producers need to balance the ratio of traditional power plants to new energy power plants. On the other hand, power transmission companies need to dynamically perceive changes in power consumption through technical means, and send instructions to major power producers (especially power producers with adjustment capabilities) through advanced communication methods, so that power producers can adjust production activities and increase or decrease power generation.

How much do you know about electricity safety in summer?

In terms of daily electricity use, Gui Xu reminds everyone to keep in mind the following five points:

First, it is necessary to reasonably control the use time of electrical appliances. In the high temperature in summer, electrical appliances should also rest in time to avoid overload operation. Once an electrical appliance is found to be overheated, it should be unplugged in time.

Second, try not to use high-power electrical appliances at the same time, such as air conditioners, ovens, etc. Avoid using high-power electrical appliances on the same power strip. Overloading the power strip can easily cause fires.

Third, regularly check whether the power lines are aging, poor contact, etc., and replace damaged electrical appliances and lines in time.

Fourth, do not use electrical appliances in a humid environment. Summer is a season of frequent showers. If water enters your home, you should cut off the power supply (turn off the switch) in time and move the electrical appliances to a dry place to prevent moisture. In addition, when sweating, do not touch live equipment to prevent electric shock.

Fifth, “turn off the power when not in use” is necessary to save electricity and be safe.
