However, the characteristics of the electric energy are that the electricity generation, the electricity transmission, the electricity transformation and the electricity utilization are completed at the same time, and the middle part is a link without storage, and the alternating current energy cannot be directly stored; i.e. how much electricity the power plant produces and how much electricity the user has to consume at the same time, this balance has to be met. If the actually generated electricity is larger than the actually consumed electricity, the surplus electric energy is converted into heat energy, and a generator of a power plant generates heat and even explodes; if the actually generated electricity is smaller than the electricity to be consumed, that is, the generated electricity is not enough, the quality of the electric energy will be reduced, for example, the light bulb becomes dark or even not bright, or the electric equipment cannot operate normally.

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
Fig. 1 is a schematic structural diagram of a power dispatching control system according to the present invention. The power scheduling control system includes: a plurality of device ports 10 connected with devices (not shown) of the power system, a plurality of data acquisition units 20, a first memory 31, a second memory 32, a data analysis unit 4, an information prompt unit 5 and a control management unit 6; wherein, each device of the power system may be, for example: transformer, metering device, measurement and control terminal, etc., but not limited thereto.
As shown in fig. 1, the plurality of device ports 10 respectively upload data to the data acquisition unit 20 at the upper end, the plurality of data acquisition units 20 respectively upload data to the first memory 31, the first memory 31 stores data and uploads data to the data analysis unit 4, the data analysis unit 4 establishes an electricity utilization model after performing data analysis, uploads a result of the data analysis and the electricity utilization model to the second memory 32, and the information prompt unit 5 issues an information prompt at an appropriate time according to the result of the data analysis and the electricity utilization model stored in the second memory 32 and sends out a control management signal through the control management unit 6.
For a city, the state of electricity utilization changes greatly during working days, weekends, legal festivals, the golden week of national day and spring festival in one year. In addition, most of the living areas are local people, so that the power utilization is relatively stable; in some areas, due to the fact that most of the lives of the workers are foreign workers, the electricity consumption is suddenly reduced in the period of the golden week or the spring festival of the national day.
Referring to fig. 1, in the power dispatching control system of the present invention, the first memory 31 stores data related to power consumption in the past years, for example, three years, in the local county or local area, the data are accumulated and uploaded to the data analysis unit 4, the data analysis unit 4 includes, but is not limited to, a central processing unit and a server, analyzes and summarizes the data related to power consumption, and sorts out power consumption and power consumption trend of power consumers, for example, a city is a first-line city in China, during the spring festival, a factory, a construction site are shut down, a worker goes away from a field, and the power consumption drops suddenly; or, a certain city is a domestic key tourist city, a large number of tourists gather in the golden week of the national celebration, and the power consumption is greatly increased; or, a certain area is an office building or a factory gathering place, the power consumption is very high between eight morning spots and eight evening spots of each day, and the power consumption is gradually reduced after eight evening spots or later, and is limited to street lamp illumination only in the period from early morning to early morning; or, a certain area is a residential area, the power consumption is very low between eight morning hours and eight evening hours every day, the power consumption is very high between eight evening hours and early morning hours, the residents return to homes, the power consumption is high, … … is particularly high when air conditioners or fans need to be used in summer, in winter, the residents in the north enjoy regional heating, do not need to turn on air conditioners or electric heaters at night, and the residents in the south use a large amount of air conditioners or electric heaters, so that the power consumption is almost … … different from that in summer, and related problems of the power consumption are not enumerated, and the above are not used for limiting the invention.
