In an actual application scene, collecting equipment 3 such as a multifunctional electric meter, an air conditioner centralized controller and the like is used for collecting power utilization parameters of each power utilization equipment of each power utilization party, the power utilization parameters are transmitted to a control center 4 with operation processing capacity through a communication management machine, the average basic power consumption and the average improved power consumption of the corresponding time period of the area are calculated according to historical power utilization parameters of a preset time period, whether the average basic power consumption of the area can be met or not is judged when the power distribution quantity given to the area by a remote main station 2 is judged to not meet the total power utilization demand of the area, if the average basic power consumption of the area cannot be met, the remote main station 2 is informed to distribute power to the area according to the average basic power consumption, the power grid is enabled to be redistributed and optimized, power distribution is scheduled from other areas, and the residential power utilization, commercial power utilization and industrial production power utilization of the area are guaranteed, industrial non-production electricity consumption is not required to be guaranteed.
In one embodiment, in the case that the distribution amount of the power grid to the area is greater than the average basic power consumption and less than the total power demand, the control center 4 redistributes the part of the power distribution amount exceeding the average basic power consumption among the plurality of power consumers in the area, and the distribution principle is as follows: and distributing according to the region position of each power consumer, wherein the amount of power distributed by enterprises close to the power generation equipment or the power transmission equipment is large.
In one embodiment, in the case that the distribution amount of the power grid to the area is greater than the average basic power consumption and less than the total power demand, the control center 4 redistributes the part of the power distribution amount exceeding the average basic power consumption among the plurality of power consumers in the area, and the distribution principle is as follows: the enterprise environment protection credit level of each power consumer is distributed, the power consumer with high level distributes more electric quantity, at the moment, the power consumer controls the power consumer corresponding to the improved power consumption to close or stand by, so that the enterprise can pay attention to the environment protection. For example, the enterprise environment protection credit levels are divided into a first level, a second level and a third level, the control center 4 receives the enterprise environment protection credit levels corresponding to the enterprises in advance, and under the condition that the distribution amount of the power grid to the area is larger than the average basic power consumption and smaller than the total power demand, the control center 4 distributes 50% of the electric quantity exceeding the average basic power consumption in the distribution amount to each first level enterprise averagely, 30% of the electric quantity exceeds each second level enterprise averagely, 20% of the electric quantity exceeds each third level enterprise averagely, and certainly, the distribution amount of the electric quantity can be adjusted.
In one embodiment, when the distribution amount of the power grid to the area is greater than the average basic power consumption and less than the total power demand, the control center 4 distributes the part of the power amount exceeding the average basic power consumption among the plurality of power consumers in the area, and at this time, the power consumers control their own power consumers corresponding to the improved power consumption to turn off or stand by, so that each enterprise is distributed with a part of the improved power consumption and is distributed by themselves.
In one embodiment, in the case that the distribution amount of the power grid to the area is larger than the average basic power consumption and smaller than the total power demand, the control center distributes the part of the distribution amount exceeding the average basic power consumption to different power consumers in different time periods, so that each enterprise can obtain enough improved power consumption in a certain time period. For example, in the period from 9 am to 6 pm in summer, the control center 4 distributes the part of the distribution power exceeding the average basic power consumption to the textile industry, and the textile industry can turn on the air conditioner at the distribution section to improve the working environment of workers.
In one embodiment, in the case that the distribution amount of the power grid to the area is greater than the average basic power consumption and less than the total power demand, the control center 4 distributes the part of the power distribution amount exceeding the average basic power consumption to the power consumers of the first fleet according to a first predetermined rule, and simultaneously distributes the part of the power distribution amount exceeding the average basic power consumption to the power consumers of the second fleet according to a second predetermined rule. The distinguishing principle of the power utilization of the first elevator bank and the power utilization of the second elevator bank is as follows: the time periods of improving electricity utilization according to urgent needs are distinguished, for example, a first elevator team electricity utilization party refers to an electricity utilization party with more urgent needs for improving electricity utilization in a time period from 9 am to 6 pm, while a time period from 6 pm to 9 am is not an urgent need for improving electricity utilization, correspondingly, a second elevator team electricity utilization party refers to an electricity utilization party with less urgent needs for improving electricity utilization in a time period from 9 am to 6 pm, while a time period from 6 pm to 9 am is a time period with a urgent need for improving electricity utilization, for example, the first gradient electricity utilization party may be a textile enterprise, and the second gradient electricity utilization party may be a mining enterprise. Preferably, the first predetermined rule is: the power transmission amount in the unit time is gradually reduced along with the time, and the second predetermined rule is as follows: the transmission of electricity in unit time increases gradually with time, so, more reasonable optimization power consumption guarantees that the electric energy obtains reasonable utilization, and for example, first predetermined law is: in the time period from 9 am to 6 pm, the amount of power delivered per unit time is V1, in the time period from 6 pm to 9 am, the amount of power delivered per unit time is V2, V1> V2, and the second predetermined rule is: the power transmission amount in unit time is V3 in the time period from 9 am to 6 am, the power transmission amount in unit time is V4 in the time period from 6 am to 9 am, and V3< V4, so that the working environment of the staff of the textile enterprises, the sufficient illumination of the field of the mining enterprises and the like are ensured. More preferably, the amount of power transmitted per unit time according to the first predetermined rule decreases nonlinearly with time, and the amount of power transmitted per unit time according to the second predetermined rule increases nonlinearly with time, for example, V1, V2, V3 and V4 are fixed values, so that more reasonable improvement of power utilization by power consumers with different properties can be realized. Of course, the amount of power delivered per unit time according to the first predetermined rule may also decrease linearly with time, and the amount of power delivered per unit time according to the second predetermined rule may also increase linearly with time.
It should be noted that, when the current power distribution amount input to the area through the remote central station 2 by the power grid does not satisfy the average basic power consumption of the area, that is, when the remote central station 2 distributes power to the area according to the average basic power consumption, the control center 4 notifies the remote central station 2 to change the improved power distribution amount to other areas to schedule power distribution from other areas, the actual power generation amount of the power generation equipment in the area cannot satisfy the demand of the power distribution amount, after the remote central station 2 schedules power distribution from other areas, the power consumption of the area is satisfied, and the power consumption and the power distribution amount of other areas cannot be balanced, at this time, the remote central station 2 needs to recalculate the power distribution amount distributed to other areas, and the power is already delivered to the area with insufficient power generation amount from the area with sufficient power generation amount.
