Fig. 1 is a schematic flow chart of a power generation proportioning method according to an embodiment of the present invention, which may be executed by a power generation proportioning device, where the device may be implemented by software and/or hardware, and may be generally integrated in a computer device such as a server. As shown in fig. 1, the method includes:
s110, determining at least two power generation modes used in the current region, and acquiring power generation cost information, carbon emission information and power generation amount information of each power generation mode in the at least two power generation modes in a past preset time period.
With the proposition of "carbon peaking" and "carbon neutralization" goals, how to minimize the cost of electricity generation and carbon emissions while meeting the demand for electricity usage within a region is a major issue of research. Therefore, at the time of the power generation cost and the carbon emission amount, it is necessary to acquire power generation cost information, carbon emission amount information, and power generation amount information for each power generation manner in the past preset time period in the current area.
Wherein, current power generation mode mainly includes: the power generation proportioning scheme provided by the embodiment of the invention mainly researches a proportioning method for obtaining at least two power generation modes under the premise of better economy or lowest carbon emission when multiple power generation modes exist in the same region. Therefore, at least two power generation methods used in the current region or at least two power generation methods that can be constructed in the current region need to be determined. The power generation modes used in the current region may be any combination of the above power generation modes, or may be the above six power generation modes at the same time, and the specific type of the power generation mode used in the current region is not limited herein.
The current region can be understood as a region where power generation equipment corresponding to at least two power generation modes needs to provide power. For example, the current area may be a certain urban area or a certain province, or may be a certain industrial park with a large power demand, and the scene of the specific area is not limited herein.
Taking the power generation equipment mainly used for the electricity consumption of residents as an example, the electricity consumption demand and the electricity consumption intensity of residents are changed in different time periods or different seasons in a day, the current factors are considered during the power generation, and the electricity consumption peak value and the electricity consumption valley value of the past preset time period are obtained.
The past preset time period may be one year or half year, and is preferably one year in consideration of fluctuation of power demand depending on seasons.
Alternatively, the power generation cost information may include the number of devices, the cost of the devices, and the unit power generation cost for each power generation manner; the carbon emission amount information includes a unit carbon emission intensity for each power generation manner; the power generation amount information includes the unit device power generation amount for each power generation manner.
The equipment quantity and the equipment cost of each power generation mode can include the plant construction cost, the labor cost, the plant construction cost and the like corresponding to the current power generation mode besides the equipment cost required by purchasing each equipment.
The unit electricity production cost can be understood as the material cost required to be consumed for producing one degree of electricity and the equipment loss cost under the current power generation mode, wherein the material cost can be understood as the coal cost required to be consumed for producing one degree of electricity by taking thermal power as an example.
The unit carbon emission intensity can be understood as the amount of carbon emitted when each power generation mode produces one degree of electricity, and the corresponding amount of carbon emitted when the number of devices used in each power generation mode is different.
The unit equipment power generation quantity can be understood as the power quantity which can be generated by each equipment and comprises a plurality of kinds of equipment under each power generation mode.
The number of the devices, the device cost and the unit device power generation amount can be obtained by various power generation device manufacturers, the unit carbon emission intensity can be obtained by accounting through carbon emission data provided by the power generation device manufacturers, and the unit carbon emission intensity can also be obtained by measuring and calculating through installing an internet of things sensor device on the power generation device. And the unit electricity production cost is mainly obtained by historical data of past time periods.
And S120, constructing an objective function according to the power generation cost information, the carbon emission information and the power generation amount information of each power generation mode in the past preset time period, and setting constraint conditions for the objective function.
Since the electricity generation proportioning scheme provided by the embodiment of the invention is studied under the condition of saving cost or further reducing carbon emission, a cost function related to control cost and a carbon emission function related to control carbon emission can be included in the construction of the objective function.
The cost function can be constructed according to the power generation cost information and the power generation amount information corresponding to the power generation modes, and if several power generation modes exist in the current region, the power generation cost information and the power generation amount information corresponding to each power generation mode are accumulated and summed, so that the total cost function corresponding to at least two power generation modes in the current region is obtained.
The carbon emission function can be constructed according to carbon emission information, power generation cost information and power generation amount information corresponding to the power generation modes, and if several power generation modes exist in the current region, the power generation cost information and the power generation amount information corresponding to each power generation mode are accumulated and summed, so that a total carbon emission function corresponding to at least two power generation modes in the current region is obtained.
By adding the obtained total cost function and the total carbon emission function, it is possible to obtain the power generation cost information, the carbon emission information, and the power generation amount information in the past preset time period according to each power generation manner to construct the objective function.
Further, when the objective function is solved, constraint conditions need to be set for the objective function, and the current constraint conditions may be that the power generation amount under at least two power generation modes corresponding to the current region is greater than or equal to the total power demand amount.
And S130, solving the generated energy of each power generation mode under the constraint condition so that the function value of the objective function meets the objective condition, thereby obtaining the power generation ratio of at least two power generation modes in a future preset time period.
The objective condition may be that the obtained function value of the objective function is minimal, or that the obtained function value of the objective function meets the expected requirements of the operator. If the obtained electricity generation ratio scheme is a better scheme in an economic angle or a carbon emission angle, the function value of the objective function needs to be further minimized.
The power generation proportion results of the at least two power generation modes in the future preset time period can be that which power generation modes need to be used when the function value of the objective function meets the objective condition and the number of the power generation equipment corresponding to each power generation mode can be obtained, wherein the number of the power generation equipment corresponding to each power generation mode can be obtained by calculation according to the obtained power generation amount of each power generation mode. When two or more power generation expressions are included in the current region, not all of the power generation methods are necessarily used, and the actual calculation result is used as the standard.
The power generation ratio can be the quantity ratio of the power generation equipment, namely the quantity value of the power generation equipment corresponding to each power generation mode is directly obtained; the power generation amount ratio of each power generation mode can be calculated, so that the number of power generation equipment corresponding to each power generation mode is calculated according to the power generation amount ratio, and the like.
The power generation proportioning method provided by the embodiment of the invention comprises the steps of firstly determining at least two power generation modes used in a current area, and acquiring power generation cost information, carbon emission information and power generation amount information of each power generation mode in the at least two power generation modes in a past preset time period; then, constructing an objective function according to the power generation cost information, the carbon emission information and the power generation amount information of each power generation mode in the past preset time period, and setting constraint conditions for the objective function; and finally, solving the generated energy of each power generation mode under the constraint condition so that the function value of the objective function meets the objective condition, thereby obtaining the power generation ratio of at least two power generation modes in a future preset time period. By adopting the technical scheme, the power generation proportioning result obtained by solving under the constraint function is more scientific by constructing the objective function for at least two power generation modes in the current area, and the influence caused by subjective factors is reduced. Meanwhile, by adopting the scheme, the technical effect of reducing carbon emission or saving cost can be further achieved under the condition of meeting the requirement of basic carbon emission.
Example two
The embodiment of the invention is further optimized on the basis of the above embodiment, and the step of constructing the objective function according to the power generation cost information, the carbon emission information and the power generation amount information of each power generation mode in the past preset time period is optimized, and the method comprises the following steps: constructing a total cost function according to the power generation cost information and the power generation amount information; constructing a total carbon emission function according to the carbon emission information, the power generation cost information and the power generation amount information; and constructing the target function according to the total cost function and the total carbon emission function. The advantage of this arrangement is that by constructing an objective function for the total cost and the total carbon emissions, the resulting electricity generation proportioning scheme when solved under the current objective function can save cost or further reduce carbon emissions.
The step of setting the constraint condition for the objective function is further optimized, and comprises the following steps: and setting a constraint condition for the objective function according to the generated energy information and the total required electric energy information, so that the sum of the generated energies of the at least two power generation modes output under the constraint condition meets the total required electric energy information.
The step of optimizing the generated energy of each power generation mode which is solved under the constraint condition so that the function value of the objective function meets the objective condition, thereby obtaining the power generation ratio of the at least two power generation modes in a future preset time period comprises the following steps: and solving the generated energy of each power generation mode when the function value of the objective function is minimum under the constraint condition, so as to obtain the power generation ratio of the at least two power generation modes in a future preset time period. The advantage of such an arrangement is that the minimum value of the objective function obtained under the constraint condition indicates that the total cost value or the total carbon emission value contained in the objective function is minimum, so that the obtained electricity generation proportioning scheme is more optimal.
As shown in fig. 2, fig. 2 is a schematic flow chart of a power generation proportioning method provided in the second embodiment of the present invention, and specifically, the method includes the following steps:
s210, determining at least two power generation modes used in the current region, and acquiring power generation cost information, carbon emission information and power generation amount information of each power generation mode in the at least two power generation modes in a past preset time period.
And S220, constructing a total cost function according to the power generation cost information and the power generation amount information.
When the electricity generation proportioning scheme is performed with cost saving or with further reduction of the carbon emission, a function related to the electricity generation cost may be first constructed, and it is conceivable that the electricity generation cost is related to the electricity generation amount, and a total cost function may be constructed based on the electricity generation cost information and the electricity generation amount information corresponding to each electricity generation manner.
An alternative embodiment, in constructing the total cost function from the power generation cost information and the power generation amount information, comprises: and constructing a sub-cost function of each power generation mode according to the number of equipment, the equipment cost, the unit power generation cost and the unit equipment power generation amount of each power generation mode, and accumulating the sub-cost functions of each power generation mode to construct a total cost function.
For example, considering that six power generation modes including thermal power generation, natural gas power generation, wind power generation, hydraulic power generation, photovoltaic power generation and nuclear power generation are included in the current region, taking power generation cost information, carbon emission amount information and power generation amount information of the past preset time period T as examples, T can be divided into N +1 time nodes T0，t1，…，tNThe number of power generation devices corresponding to each power generation mode is respectively recorded as: x is the number of1，x2，x3，x4，x5And x6(ii) a The cost of the power generation equipment corresponding to each power generation mode is respectively recorded as: f. of1，f2，f3，f4，f5And f6(ii) a For any i equal to 0,1, …, N-1, each power generation mode is set at tiTo ti+1The corresponding unit electricity production cost in the time period is respectively recorded as: c. C1i，c2i，c3i，c4i，c5iAnd c6i(ii) a For any i equal to 0,1, …, N-1, each power generation mode is set at tiTo ti+1The corresponding unit equipment power generation amount in the time period is respectively recorded as: e.g. of the type1i，e2i，e3i，e4i，e5iAnd e6i。
When constructing the sub-cost function of each power generation mode according to the number of equipment, the equipment cost, the unit power generation cost and the unit equipment power generation amount of each power generation mode, the first cost sub-function can be recorded as tc1And tc is then1Can be expressed by the following expression:
the total cost function TC constructed by adding up the sub-cost functions for each power generation mode can be expressed by the following expression:
and S230, constructing a total carbon emission function according to the carbon emission information, the power generation cost information and the power generation amount information.
In constructing the function regarding the carbon emission amount, it is conceivable that the carbon emission amount is related to the power generation cost and the power generation amount, and the total carbon emission amount function may be constructed from the carbon emission amount information, the power generation cost information, and the power generation amount information corresponding to each power generation manner.
An alternative embodiment, in constructing the total carbon emission function based on the carbon emission information, the power generation cost information, and the power generation amount information, comprises: and constructing a function of the sub-carbon emission of each power generation mode according to the unit carbon emission intensity, the equipment number and the unit equipment power generation amount of each power generation mode, and accumulating the functions of the sub-carbon emission of each power generation mode to construct a function of the total carbon emission.
Illustratively, on the basis of step S230, for any i ═ 0,1, …, N-1, each power generation manner is at tiTo ti+1The corresponding intensity per unit carbon emission over the time period is respectively recorded as: d1i，d2i，d3i，d4i，d5iAnd d6i. Constructing a function of the amount of carbon emission per power generation mode according to the intensity of carbon emission per power generation mode, the number of devices and the amount of power generated per device, wherein the first function of the amount of carbon emission per power generation mode can be denoted as td1Td is then1Can be expressed by the following expression:
the total carbon emission function TD constructed by adding the function of the amount of carbon emissions per power generation mode can be expressed by the following expression:
and S240, constructing an objective function according to the total cost function and the total carbon emission function.
The objective function M may be expressed in the following form according to the total cost function TC constructed at step S220 and the total carbon emission function TD constructed at step S230:
M＝TC+TD (5)
in the actual design of the objective function, the total cost function and the total carbon emission function generally occupy different proportions, and for this reason, the electricity generation proportioning scheme provided by the embodiment of the present invention provides an optional embodiment, and when the objective function is constructed according to the total cost function and the total carbon emission function, the method includes: acquiring a first weight set for a total cost function, and acquiring a second weight set for a total carbon emission function; and summing the product of the total cost function and the first weight and the product of the total carbon emission function and the second weight to obtain an objective function.
Then the first weight ω is designed separately for the total cost function and the total carbon emission function1And a second weight ω2The objective function M can then be expressed in the form:
M＝ω1TC+ω2TD (6)
in the formula (6), ω1And ω2Satisfy the relation omega1+ω2＝1。
According to the formula (6), the total cost function and the total carbon emission function are in inverse relationship, and if the carbon emission needs to be increased properly under the condition of controlling the cost, the current carbon emission needs to meet the minimum standards given by the government. It is also possible to reduce the amount of carbon emissions as much as possible, thereby increasing the overall cost. Further, an intermediate solution may be taken, how cost-effective the enhanced electricity generation proportioning solution is in the best case to meet government-given carbon emission minimum standards.
And S250, setting a constraint condition for the objective function according to the generated energy information and the total required electric energy information, so that the sum of the generated energy of at least two power generation modes output under the constraint condition meets the total required electric energy information.
For any i-0, 1, …, N-1, the total power demand is at tiTo ti+1During the time period is XiTile, then the constraint can be expressed in the form:
x1e1i+x2e2i+x3e3i+x4e4i+x5e5i+x6e6i≥Xi (7)
