The price signal guides the user to reasonably adjust and improve the electricity utilization structure and the electricity utilization mode.

The real-time electricity price is a dynamic pricing mechanism, and the dynamic updating period can reach 1h or even shorter.

2. The load of each node of the power grid is rearranged in time and space in the peak power utilization period, the load curve of the system is smoothed by shifting the peak and filling the valley through ordered movement in time, and the blockage is eliminated and the loss of the system is reduced through coordination and coordination in space. The method specifically comprises the following steps:
(1) combining the monitoring data of people flow and outdoor illuminance, the load monitoring device automatically adjusts the brightness and color temperature of the partition switch according to preset regulation and control parameters, divides reasonable working time periods according to different functions of the lighting areas, and automatically turns on and off the lighting system in a timing period mode;
(2) limiting the charging time of the charging piles, such as charging at night and charging at valley time, and planning the charging time period and the number of the charging piles in operation according to the working time period and the traffic flow;
(3) the operation parameters of the air conditioning system are adjusted according to the temperature and the humidity of the environment during the peak period of power utilization, the air conditioning load of a public area is dynamically adjusted by combining people stream data information, the load input is reduced when people are few, and the load is increased when people are large. During peak hours the air conditioning system fine-tunes the room temperature without affecting comfort, for example: the air conditioner room temperature is increased from 25 ℃ to 26 ℃, the influence on the comfort of a human body can be ignored, and the energy consumption of the air conditioner can be reduced by 23 percent. The air conditioner load has a quick response capability, and within a period of time (15-30 min) after the operation is stopped, the influence on the electricity utilization experience of a user is little, and a large amount of electric power can be saved.
(4) And controlling the public electric equipment by adopting a service mode of switching in or switching out in a certain time period and a partitioned area. According to the regulation and control of people flow information acquired by the video monitoring device, meaningless energy waste and equipment aging caused by long-time electrification of regional equipment without people flow for a long time are avoided.
3. The monitoring module of the load monitoring device monitors the power grid frequency, on the premise that the power consumption experience of a user is not influenced, the main station platform controls the load monitoring device to adjust operation parameters of power consumption equipment according to the power grid frequency so as to change the power consumption, the power consumption is reduced or quit when the frequency is low, and the power grid frequency is put into order when being recovered to be normal. The quick adjustment characteristic of the frequency response load enables the frequency response load to play a role similar to the primary frequency modulation of a unit, and the frequency response load can participate in the power frequency adjustment of the system in two ways: the first is a switch type regulation mode, and when the frequency of a power grid is lower than a preset threshold value, the load is directly cut off; and secondly, in a temperature control type adjusting mode, when the frequency of the power grid is lower than a preset threshold value, the set temperature of the air-conditioning isothermal control type electric equipment is increased so as to reduce the electric power. Compared with the switch type adjusting mode, the temperature control type adjusting mode has smaller influence on the comfort level of the electricity consumption of the user, but the adjusting amount is relatively smaller. In order to prevent a large number of frequency response loads from simultaneously acting to cause new impact on the power grid frequency and avoid frequency oscillation, different parameters such as action threshold values, action/recovery time delay and the like need to be set for a response device of the frequency response loads according to the power grid requirements. This allows a better balance between user comfort and grid frequency stability. The method specifically comprises the following steps:
when the real-time power supply frequency of the power grid is lower than the lower limit value of the frequency, cutting off all the power loads except the loads necessary for production and life; setting action thresholds F1, F2 and F3, wherein 50Hz is larger than F1, F2 and F3, and when the grid frequency is reduced to F1, performing first-order load adjustment to increase the refrigeration set temperature of the air conditioning system by 2 degrees; closing public supporting electric facilities in the unmanned area; when the power grid frequency is reduced to F2, performing second-order load adjustment, and increasing the refrigeration set temperature of the air conditioning system by 5 degrees; dimming control is performed on a lighting system in a public area, and the dimming control is reduced according to the ambient light illumination; and when the power grid frequency is reduced to F3, performing three-order load adjustment, only keeping load power supply necessary for production and life, and cutting off the power supply of other air conditioning systems, lighting systems in public areas and public matching power utilization facilities.
The present invention is not limited to the above-described embodiments, which are merely preferred embodiments of the present invention, and the present invention is not limited thereto, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
