Other contents of this embodiment are the same as those of the first embodiment, and specific reference may be made to the description of the first embodiment, which is not repeated herein.
In summary, according to the embodiments of the present invention, the current state of the target power plant is determined according to the power consumption and the power generation amount, when the power generation is excessive, the power consumption is increased, and when the power generation is insufficient, the power consumption is decreased, so that the power consumption fluctuates along with the fluctuation trend of the power generation amount, and the power consumption and the power generation amount reach a balanced state as much as possible, thereby ensuring that the generated power is fully utilized.
Example three:
this embodiment provides a further solution on the basis of the power regulating method provided in the second embodiment, in this embodiment, the step S701 of determining the current state of the target power plant according to the current power consumption and the current power generation amount may include the steps as shown in fig. 9:
step S901, summing the current power consumption to obtain a first power consumption.
P may be used in this embodiment1To represent the first amount of power, then:
wherein N is the number of the target electrical appliances, the target electrical appliances are sorted from 1 to N, pnThe current electricity consumption of the target electrical appliance with the serial number n.
And step S902, determining a second electric quantity according to the first electric quantity and a preset statistical model.
In the power supply range of the target power plant, besides the target electrical appliance, other electrical appliances exist, and the electrical energy is consumed, so that the first electricity consumption obtained according to the current electricity consumption of the target electrical appliance is only a part of the total electricity consumption of all the electrical appliances in the power supply range, and the total electricity consumption is the second electricity consumption.
P may be used in this embodiment2To represent the second amount of power, then:
P2＝f(P1)
wherein f () is P2And P1The functional relationship between them, i.e. the statistical model.
According to different situations, different statistical models can be set, and the following description is given by two simple statistical models:
the first model is used for counting the first electric quantity and the second electric quantity within a preset time, wherein the preset time can be a week, a month, a quarter or a year. Determining a proportionality coefficient between the first electric quantity and the second electric quantity in the period of time, in this embodiment, K may be used to represent the proportionality coefficient, and then K and the first electric quantity may be used to estimate the second electric quantity, which may be expressed as follows:
P2＝KP1
and a second model, counting the first electric quantity and the second electric quantity within a preset time, wherein the preset time can be a week, a month, a quarter or a year. Segmenting the preset time according to a certain time interval, and determining a proportionality coefficient of the first electric quantity and the second electric quantity in each time segment, for example, segmenting at one hour interval in one week time, and then segmenting into 168 segments in total, in this embodiment, M may be used to represent the number of segments, in each time segment, one proportionality coefficient is determined, then 168 proportionality coefficients in total are determined, in this embodiment, k may be usedmTo represent the proportionality coefficient, wherein M is more than or equal to 1 and less than or equal to M, in each subsequent week, the proportionality coefficient k of the corresponding time period in one week can be usedmAnd the first amount of power to estimate the second amount of power, which may be formulated as follows:
P2＝kmP1
in practical applications, other statistical models may be selected according to specific situations, which is not specifically limited in this embodiment.
And step S903, judging whether the second electric quantity is smaller than the current generated energy.
P may be used in this embodiment3To represent the current power generation amount.
If the second electric quantity is smaller than the current electric quantity, namely P2<P3Then step S904 is executed, if the second electric quantity is larger than the current electric quantity, i.e. P2>P3Then step S905 is executed, if the second electric quantity is equal to the current electric quantity, i.e. P2＝P3Then step S906 is performed.
Preferably, the following determination method may also be adopted: if the second electric quantity is smaller than the current electric quantity and the absolute value of the difference value of the second electric quantity and the current electric quantity is larger than a preset threshold value, namely P3-P2>Then step S904 is executed, wherein the threshold is represented by using the second electric quantity, and if the second electric quantity is larger than the current electric quantity and the absolute value of the difference between the two is larger than a preset threshold, that is, P is greater than the preset threshold2-P3>Then, step S905 is executed, if the absolute value of the difference between the second electric quantity and the current electric quantity is not greater than the preset threshold, that is, | P2-P3|<Then step S906 is performed.
And step S904, determining the current state of the target power plant as a power generation surplus state.
And step S905, determining the current state of the target power plant as an insufficient power generation state.
And step S906, determining the current state of the target power plant as a power generation balance state.
Other contents of this embodiment are the same as those of the embodiment two, and specific reference may be made to the description of the embodiment two, which is not repeated herein.
In summary, according to the embodiment of the present invention, first electric quantity is obtained, then second electric quantity is determined according to the first electric quantity and a preset statistical model, and the current state of the target power plant is determined by determining the relationship between the second electric quantity and the current power generation amount. On the premise that the statistical model is properly selected, the calculation accuracy can be improved, and the control on the power consumption is more accurate.
Example four:
in this embodiment, as shown in fig. 10, after determining that the power consumption adjustment information is the first adjustment information for increasing the power consumption in step S702, the method may further include:
and step S704, determining the amplitude information of the electricity consumption required to be increased according to the current electricity consumption, the current electricity generation and a preset theoretical maximum electricity consumption.
For a target electrical appliance, the operating power has a maximum limit, and the power consumption also has a maximum limit, i.e. the theoretical maximum power consumption. When determining the adjustment amplitude information, the server needs to consider the theoretical maximum power consumption of each target electrical appliance, otherwise, the adjustment amplitude may be too large, so that the adjusted power consumption exceeds the theoretical maximum power consumption of the target electrical appliance, which is obviously unreasonable and should be avoided.
Examples are as follows:
assuming that the total number of the target electrical appliances is 5, the current electricity consumption of each target electrical appliance is 10 degrees, summing the current electricity consumption to obtain a first electricity consumption of 50 degrees, determining a second electricity consumption according to the first electricity consumption and a preset statistical model, assuming that the statistical model is P2＝3P1Then, it is determined that the second electric quantity is 150 degrees, and if the current electric quantity is 160 degrees, then 10 degrees of electric quantity is added, at this time, it is determined that the magnitude of the increase of the electric quantity required by each target electric appliance is 2 degrees, so that the balance relationship between the electric quantity and the electric quantity can be maintained. However, if the theoretical maximum power consumption of one of the target electrical appliances is 10 degrees, the theoretical maximum power consumption cannot be increased continuously, and the theoretical maximum power consumption of the other target electrical appliances is 15 degrees, the target electrical appliance with the theoretical maximum power consumption of 10 degrees can be determined to have the range of increasing the power consumption of 2.5 degrees, so that the balance relation between the power consumption and the power generation amount is still maintained within a reasonable range.
Step S705, adding the amplitude information of the required increased power consumption into the first adjustment information.
As shown in fig. 11a, the magnitude information of the required increase power usage may be included in the message body.
After determining that the electricity consumption adjustment information is the second adjustment information for reducing the electricity consumption amount in step S703, the method further includes:
and step S706, determining the amplitude information of the required electricity consumption reduction according to the current electricity consumption, the electricity generation amount and the preset theoretical minimum electricity consumption.
For a target appliance, the operating power has a minimum limit, and the power consumption also has a minimum limit, i.e., the theoretical minimum power consumption. When determining the adjustment amplitude information, the server needs to consider the theoretical minimum power consumption of each target electrical appliance, otherwise, the adjustment amplitude may be too large, so that the adjusted power consumption is smaller than the theoretical minimum power consumption of the target electrical appliance, which is obviously unreasonable and should be avoided.
In step S707, the information of the magnitude of the required reduction in the used amount of electricity is added to the second adjustment information.
As shown in fig. 11b, the magnitude information of the required reduction power usage may be included in the message body.
Other contents of this embodiment are the same as those of the embodiment two, and specific reference may be made to the description of the embodiment two, which is not repeated herein.
In summary, according to the embodiments of the present invention, firstly, the amplitude information of the required increase power consumption (or the amplitude information of the required decrease power consumption) is determined according to the current power consumption, the current power generation amount, and the preset theoretical maximum power consumption (or the theoretical minimum power consumption), then the amplitude information of the required increase power consumption is added to the first adjustment information (or the second adjustment information), and the adjustment is accurately performed according to the actual conditions of each target electrical appliance, and in this process, the theoretical maximum power consumption (or the theoretical minimum power consumption) is considered, so that the adjustment rationality is ensured.
Example five:
the present embodiment provides a further solution on the basis of the power adjusting method provided by each of the above embodiments, in this embodiment, as shown in fig. 12, after controlling each target electrical appliance to adjust the power consumption according to the corresponding power consumption adjusting information in step S104, the method further includes:
step S1201, obtaining feedback information of each target electrical appliance;
step S1202, a fault electric appliance is screened out according to the feedback information, and the fault electric appliance is the target electric appliance which is not fed back or the feedback information is regulation failure information;
