[0036] Figure 1 This is a flowchart of a method for generating a production plan provided by an embodiment of the present invention. This embodiment is applicable to the case of generating a production plan in a production task scenario supported by a generator set. The method can be executed by a production plan generating device. The production plan generating device can be implemented in the form of hardware and / or software. The production plan generating device can be configured in a terminal device. Figure 1 As shown, the method includes:

[0037] S110, obtaining electricity consumption capacity data corresponding to at least one production workshop in a production department.

[0038] Specifically, the production department is the department in an industrial enterprise responsible for product manufacturing or production processing, and the production workshop refers to the workplace set up in the production department for product manufacturing or production processing. For example, when the production department is a garbage disposal department, the production workshops include but are not limited to the kitchen workshop, anaerobic workshop, kitchen waste workshop, manure workshop, sewage workshop, etc. The specific production content of the production department or production workshop is not limited here, and can be customized according to actual needs.

[0039] In this embodiment, the power consumption capacity data includes the unit power consumption of the workshop and the initial workshop capacity corresponding to the initial shift schedule, and the unit power consumption of the workshop represents the power consumption per unit capacity.

[0040] Specifically, the historical workshop capacity and the historical active power corresponding to the historical workshop capacity are obtained, and the ratio of the historical active power to the historical workshop capacity is used as the unit power consumption of the workshop. For example, the unit power consumption E of the jth production workshop is dpj It is expressed by the following formula:

[0041]

[0042] Among them, E d represents the historical active power of the jth production workshop, Y d represents the historical workshop capacity of the jth production workshop. For example, the unit of power consumption of the workshop is expressed as kWh / ton.

[0043] The production plan in this embodiment is a production plan generated for a power generation schedule. Specifically, the initial scheduling time indicates the power generation duration pre-set for the generator set for the current power generation schedule, and the initial workshop capacity indicates the workshop capacity pre-set for the production workshop for the current power generation schedule. For example, for power generation schedule A, the initial scheduling time can be 4 hours, and the initial workshop capacities of production workshop A and production workshop B are 3 tons and 5 tons respectively. For power generation schedule B, the initial scheduling time can be 8 hours, and the initial workshop capacities of production workshop A and production workshop B are 6 tons and 10 tons respectively.

[0044] S120: Determine the initial energy demand of the production department according to the unit power generation of the power generating set and at least one power consumption capacity data.

[0045] Specifically, the generator set includes at least one generator, which is a device that converts electrical energy into electrical energy, wherein the electrical energy is non-renewable energy or renewable energy. Among them, non-renewable energy is coal, oil or natural gas, etc., and renewable energy is water, wind, solar energy and biomass energy, etc. Exemplarily, biomass energy is crop straw, wood waste or biogas, etc. The electrical energy that drives the generator set is not limited here, and can be customized according to actual needs.

[0046] In this embodiment, the unit power generation represents the power output of the power energy in unit measurement. For example, when the power energy is coal or wood fertilizer, the unit measurement is a weight unit, such as 1 ton; when the power energy is oil, natural gas or biogas, the unit measurement is a volume unit, such as 1m 3 .

[0047] In an optional embodiment, the method also includes: taking the accumulated value of historical output power corresponding to at least one generator as the total output power, taking the accumulated value of historical energy flow corresponding to at least one generator as the total energy flow, and taking the ratio of the total output power to the total energy flow as the unit power generation of the generator set.

[0048] The historical output power represents the real-time output power of the generator at a certain historical moment, and the historical energy flow represents the flow of electric energy used to drive the generator to output the historical output power. g It is expressed by the following formula:

[0049]

[0050] Among them, P gi represents the historical output power of the i-th generator in the generator set, Q gi Represents the historical energy flow of the i-th generator in the generator set. For example, the unit of power generation is expressed in kWh / m 3 .

[0051] Specifically, based on at least one electricity consumption capacity data, the power consumption of at least one production workshop corresponding to each workshop is determined; wherein the power consumption capacity data corresponds to the power consumption of the workshop one-to-one; the accumulated value of the power consumption of at least one workshop is taken as the total power consumption of all production workshops, and the ratio of the total power consumption to the unit power generation is taken as the initial energy demand.

[0052] For example, the initial energy requirement V t It is expressed by the following formula:

[0053]

[0054] Among them, Y pjrepresents the initial workshop capacity of the jth production workshop, E dpj ·Y pj represents the power consumption of the jth production workshop, Indicates the total power consumption.

[0055] S130: Determine the estimated power generation time of the generator set according to the initial energy demand and energy production capacity data.

[0056] Specifically, energy capacity data characterizes the ability of an energy production system to produce electrical energy.

[0057] In an optional embodiment, the energy production capacity data includes the unit energy output of electric energy. Accordingly, the expected power generation time of the generator set is determined based on the initial energy demand and the energy production capacity data, including: taking the ratio of the initial energy demand to the unit energy output as the expected power generation time of the generator set; wherein the unit energy output represents the output of electric energy per unit time.

[0058] Specifically, the energy output flow collected by the energy flow meter set in the energy output system within the collection time is obtained, and the ratio of the energy output flow to the collection time is used as the unit energy output.

[0059] In another optional embodiment, the energy production capacity data includes the unit energy output and energy stock of electric energy. Accordingly, the expected power generation time of the generator set is determined based on the initial energy demand and the energy production capacity data, including: taking the difference between the initial energy demand and the energy stock as the incremental energy demand; taking the ratio of the incremental energy demand to the unit energy output as the expected power generation time of the generator set.

[0060] Specifically, when the energy production system has energy storage function, the energy production capacity data also includes energy stock, which represents the storage amount of electric energy in the energy production system.

[0061] Exemplarily, the estimated power generation time T is expressed by the following formula:

[0062]

[0063] Among them, V cm represents the storage capacity of the mth energy storage mechanism in the energy output structure, Q cn represents the unit output of the nth energy production unit in the energy production system, ∑V cm represents the energy stock, ∑Q cn It represents the unit energy output.

[0064] S140: If the estimated power generation time exceeds the initial shift schedule, a production plan is generated according to the estimated power generation time and at least one initial workshop capacity.

[0065] In an optional embodiment, the optimization direction of the production plan includes extending the power generation time of the generator set and / or reducing the workshop capacity of the production workshop. Specifically, when the optimization direction of the production plan only includes extending the power generation time of the generator set, the initial workshop capacity of each production workshop is kept unchanged, and the initial scheduling time is extended to obtain the planned scheduling time; when the optimization direction of the production plan only includes reducing the workshop capacity of the production workshop, the initial scheduling time is kept unchanged, and the initial workshop capacity of one or more production workshops is respectively reduced to obtain the planned workshop capacity.

[0066] In an optional embodiment, a production plan is generated based on the expected power generation time and at least one initial workshop capacity, including: determining the planned shift time based on the expected power generation time; for each production workshop, using the initial workshop capacity of the production workshop as the planned workshop capacity of the production workshop.

[0067] Specifically, the estimated power generation time is used as the planned shift time, or the estimated power generation time is rounded up to obtain the planned shift time.

[0068] For example, assuming that the initial shift time is 8 hours, the expected power generation time is 10 hours, and the initial workshop capacities of the three production workshops are 3 tons, 5 tons, and 2 tons, respectively, for a total of 10 tons. In this embodiment, the generated production plan is a planned shift time of 10 hours, and the planned workshop capacities of each workshop are 3 tons, 5 tons, and 2 tons, respectively.

[0069] The advantage of this setting is that by extending the power generation time of the generator set, it achieves the purpose of alleviating the problem that the generator set's short power generation time cannot maintain the electricity demand of the production task, avoids the situation of purchasing municipal electricity due to insufficient power generation, and thus reduces the electricity cost of the production task.

[0070] In another optional embodiment, a production plan is generated based on the expected power generation time and at least one initial workshop capacity, including: taking the initial scheduling time as the planned scheduling time; determining the planned total capacity based on the expected power generation time, the planned scheduling time and at least one initial workshop capacity; wherein the planned total capacity represents the planned capacity of all production workshops corresponding to the planned scheduling time; determining the total reduced capacity based on the planned total capacity and at least one initial workshop capacity; and adjusting at least one initial workshop capacity based on the total reduced capacity and the production weights corresponding to the at least one production workshop to obtain the planned workshop capacity of each production workshop.

[0071] Specifically, the cumulative value of at least one initial workshop capacity is taken as the initial total capacity, the ratio of the initial total capacity to the expected power generation time is taken as the unit time capacity, the product of the unit time capacity and the planned shift time is taken as the planned total capacity, and the difference between the initial total capacity and the planned total capacity is taken as the total reduced capacity. Among them, the unit time capacity represents the expected production capacity of all production workshops in unit time.

[0072] For example, the planned total capacity Y t It is expressed by the following formula:

[0073]

[0074] Wherein, T′ represents the planned shift time or the initial shift time.

[0075] For example, assuming that the initial scheduling time is 8 hours, the expected power generation time is 10 hours, and the initial workshop capacity of the three production workshops is 3 tons, 5 tons and 2 tons respectively, then the initial total capacity is 10 tons, the unit time capacity is 1 ton / hour, the planned total capacity is 8 tons, and the total reduced capacity is 2 tons.

[0076] In an optional embodiment, according to the total reduced capacity and the production weight corresponding to at least one production workshop, at least one initial workshop capacity is adjusted to obtain the planned workshop capacity of each production workshop, including: determining at least one capacity weight according to the production weight corresponding to at least one production workshop; according to the total reduced capacity and at least one capacity weight, adjusting at least one initial workshop capacity to obtain the planned workshop capacity of each production workshop.

[0077] Specifically, the production weight indicates the importance of the production workshop in the production process. The larger the production weight, the more important the production workshop is, the smaller the capacity reduction it needs to bear, and the smaller the capacity weight. Conversely, the smaller the production weight, the less important the production workshop is, the greater the capacity reduction it needs to bear, and the greater the capacity weight. Among them, the capacity weight indicates the proportion of the total capacity reduction that the production workshop needs to bear.

[0078] Taking the above example, the total capacity reduction is 2 tons. Assuming that the production weights of the three production workshops are 0.4, 0.5 and 0.1 respectively, the capacity weights of the three production workshops are approximately 0.1724, 0.1379 and 0.6897 respectively, and the workshop capacity reductions of the three production workshops are 0.3448 tons, 0.2758 tons and 1.3794 tons respectively. Correspondingly, the planned workshop capacities of the three production workshops are 2.6552 tons, 4.7242 tons and 0.6206 tons respectively.

[0079] In a specific embodiment, when the production weights of the three production workshops are all 1, it means that the total reduced capacity of 2 tons will be evenly distributed to the three workshops, that is, the reduced capacity of the three production workshops is approximately 0.6667 tons, and the planned workshop capacities of the three production workshops are 2.3333 tons, 4.3333 tons and 1.3333 tons respectively.

[0080] In another optional embodiment, the method of adjusting at least one initial workshop capacity according to the total reduced capacity and the production weight corresponding to at least one production workshop to obtain the planned workshop capacity of each production workshop includes: determining the workshop ranking result of at least one production workshop according to the production weight corresponding to at least one production workshop; taking the production workshop with the smallest production weight in the workshop ranking result as the designated workshop, and taking the difference between the initial workshop capacity and the total reduced capacity of the designated workshop as the reference workshop capacity; if the reference workshop capacity is greater than or equal to zero, taking the reference workshop capacity as the planned workshop capacity of the designated workshop, and taking the initial workshop capacity of each production workshop except the designated workshop in the workshop ranking result as the planned workshop capacity of the production workshop; if the reference workshop capacity is less than zero, setting the planned workshop capacity of the designated workshop to zero, deleting the designated workshop from the workshop ranking result, and returning to execute the step of taking the production workshop with the smallest production weight in the workshop ranking result as the designated workshop.

[0081] Taking the above example as an example, assuming that the three production workshops are workshop A, workshop B and workshop C, the workshop ranking results are workshop B, workshop A and workshop C. Since the initial workshop capacities of workshop A, workshop B and workshop C are 3 tons, 5 tons and 2 tons respectively, and the total reduced capacity is 2 tons, in this embodiment, the planned workshop capacities of workshop A, workshop B and workshop C are 3 tons, 5 tons and 0 tons respectively.

[0082] In another example, assuming that the workshop ranking results are workshop B, workshop A, and workshop C, the initial workshop capacities of workshop A, workshop B, and workshop C are 3 tons, 5 tons, and 1 ton, respectively, and the total reduced capacity is 2 tons, then in the first iteration process, workshop C is the designated workshop, and the planned workshop capacity of workshop C is 0 tons. In the second iteration process, workshop A is the designated workshop, and the planned workshop capacity of workshop A is 2 tons, that is, in this embodiment, the planned workshop capacities of workshop A, workshop B, and workshop C are 2 tons, 5 tons, and 0 tons, respectively.

[0083] Compared with the above-mentioned embodiment of adjusting the production capacity in proportion, this embodiment retains the production capacity of the production workshop with a larger production weight to the greatest extent.

[0084] The advantage of this setting is that by reducing the workshop production capacity of the production workshop, the purpose of alleviating the inability of the generator set to maintain the electricity demand of heavier production tasks is achieved, avoiding the situation of purchasing municipal electricity due to insufficient power generation, thereby reducing the electricity cost of production tasks.

[0085] In the actual production operation process, one or more power generation schedules are usually set for the entire production task within a preset period (such as within a day). In some specific embodiments, only one power generation schedule is set within the preset period, and the production plan can be generated by extending the power generation time of the generator set, or by reducing the workshop capacity of the production workshop. If multiple power generation schedules are set within the preset period, if the current power generation schedule is not the last power generation schedule within the preset period, a production plan corresponding to the current power generation schedule is generated by reducing the workshop capacity of the production workshop. If the current power generation schedule is the last power generation schedule within the preset period, a production plan corresponding to the current power generation schedule is generated by extending the power generation time of the generator set.

[0086] The advantage of this setting is that it avoids the causal impact of the extension of the current power generation schedule on the subsequent power generation schedule within the preset period on the time series, and minimizes the capacity transfer effect caused by the optimization of the production plan of the current power generation schedule.

[0087] Based on the above embodiment, optionally, the production plan also includes newly added scheduling time within the time interval corresponding to the low-peak electricity price. Accordingly, the production plan is generated according to the expected power generation time and at least one initial workshop capacity, and also includes: for each production workshop, determining the additional production time of the production workshop according to the initial workshop capacity and the planned workshop capacity of the production workshop; and taking the maximum value of the at least one additional production time as the newly added scheduling time within the time interval corresponding to the low-peak electricity price.

[0088] Specifically, the low-peak electricity price represents a lower price range of the city electricity, and the time interval corresponding to the low-peak electricity price represents at least one time interval corresponding to the low-peak electricity price within the preset period. Exemplarily, when the preset period is one day, the time interval corresponding to the low-peak electricity price may be 00:00-6:00, and when the preset period is two days, the time interval corresponding to the low-peak electricity price includes 00:00-6:00 on the first day and 00:00-6:00 on the second day.

[0089] Specifically, the newly added shift time indicates the working time of the power generation shift that is not set in advance. For example, assuming that the preset cycle is one day, and there are 3 power generation shifts set, then a power generation shift corresponding to the time interval corresponding to the low-peak electricity price is added to the production plan, that is, the newly added power generation shift is set in the time interval corresponding to the low-peak electricity price.

[0090] Specifically, the ratio of the initial workshop capacity of the production workshop to the planned shift time is taken as the workshop unit capacity, the product of the workshop unit capacity and the planned workshop capacity is taken as the basic production time, and the difference between the planned shift time and the basic production time is taken as the additional production time of the production workshop.

[0091] Among them, the workshop unit capacity refers to the initial production capacity of the production workshop in unit time, and the basic production time refers to the time required for the production workshop to complete the planned workshop capacity within the planned shift time. Since the planned workshop capacity is less than or equal to the initial workshop capacity, the basic production time is less than or equal to the planned shift time, and accordingly, the additional production time is greater than or equal to zero.

[0092] The advantage of this setting is that, in the optimization direction of reducing the workshop capacity of the production workshop, by adding new power generation shifts, it not only solves the problem that the reduced capacity of the current power generation schedule may cause the power generation time of the subsequent power generation schedule to be excessively extended, but also minimizes the electricity cost generated when switching to the mains power strategy.

[0093] In an optional embodiment, when the optimization direction of the production plan includes extending the power generation time of the generator set and reducing the workshop capacity of the production workshop, the mapping relationship between the power generation time of the generator set and the workshop capacity of the production workshop can be optimized and balanced. The value range of the planned scheduling time is greater than the initial scheduling time and less than the expected power generation time. The total reduced capacity in this embodiment is greater than zero and less than the total reduced capacity in the above embodiment.

[0094] Based on the above embodiment, optionally, the method also includes: if the expected power generation time is less than the initial scheduling time, the expected power generation time is used as the planned scheduling time, and for each production workshop, the initial workshop capacity of the production workshop is used as the planned workshop capacity of the production workshop to obtain a production plan.

[0095] The advantage of this setting is that it reduces the energy waste caused by the longer power generation time of the generator set.

[0096] The technical solution of this embodiment determines the initial energy demand of the production department based on the unit power generation of the generator set and the power consumption capacity data corresponding to at least one production workshop in the production department, and determines the expected power generation time of the generator set based on the initial energy demand and the energy production capacity data. If the expected power generation time exceeds the initial scheduling time, a production plan is generated based on the expected power generation time and at least one initial workshop capacity, which solves the problem of poor accuracy of production plans made based on experience, and achieves the purpose of intelligent optimization of production plans from the dimension of the power generation time required for the generator set to support production tasks, thereby reducing the electricity cost of production tasks.

[0097] Figure 2This is a flow chart of another method for generating a production plan provided by an embodiment of the present invention. This embodiment further refines the method for generating a production plan in the above embodiment. Figure 2 As shown, the method includes:

[0098] S210, obtaining electricity consumption capacity data corresponding to at least one production workshop in a production department.

[0099] S220: Determine the initial energy demand of the production department according to the unit power generation of the power generating set and at least one power consumption capacity data.

[0100] S230: Determine the estimated power generation time of the generator set according to the initial energy demand and energy production capacity data.

[0101] S240: If the estimated power generation time exceeds the initial shift schedule, a production plan is generated according to the estimated power generation time and at least one initial workshop capacity.

[0102] S210-S240 in this embodiment are similar to those in the above embodiment. Figure 1 The S110 - S140 shown correspond to the same or similar ones, and will not be described in detail in this embodiment.

[0103] S250: Determine active power corresponding to at least one production workshop according to the production plan.

[0104] Specifically, the power generation schedule of the generator set is set according to the planned shift time in the production plan, and the planned workshop capacity is arranged for each production workshop according to the production plan.

[0105] Specifically, active power represents the power value required by the production equipment in the production workshop to complete the planned workshop capacity. Exemplarily, the active power can be obtained by monitoring and collecting the production equipment in the production workshop using a power data acquisition system.

[0106] S260: Determine a set power corresponding to at least one generator in the generator set according to at least one active power.

[0107] In an optional embodiment, based on at least one active power, the set power corresponding to at least one generator in the generator set is determined, including: taking the accumulated value of at least one active power as the total active power corresponding to all production workshops, and taking the ratio of the total active power to the number of generators in the generator set as the set power of each generator.

[0108] In this embodiment, the total active power is evenly distributed to each generator in the generator set.

[0109] In another optional embodiment, the set power corresponding to at least one generator in the generator set is determined based on at least one active power, including: taking the accumulated value of at least one active power as the total active power corresponding to all production workshops, and taking the unset generator in the generator set as the designated generator; if the total active power is greater than the rated power of the designated generator, then taking the rated power as the set power of the designated generator, and taking the difference between the total active power and the rated power as the total active power, and returning to execute the step of taking the unset generator in the generator set as the designated generator; if the total active power is less than or equal to the rated power of the designated generator, then taking the total active power as the set power of the designated generator, and setting the set power of the unset generator in the generator set to zero.

[0110] For example, assuming that the generator set includes 4 generators, A to D, with a rated power of 70 kWh and a total active power of 200 kWh, if the random order of the 4 generators in the generator set is generator A, generator B, generator C and generator D, then the set powers corresponding to generator A, generator B, generator C and generator D are 70 kWh, 70 kWh, 60 kWh and 0 kWh, respectively.
