Description

Technical Field

[0001] The present invention relates to the field of energy storage technology, and in particular to a method and system for energy storage investment planning based on electrification improvement. Background Art

[0002] With the development of science and technology, our lives are becoming increasingly convenient. In today's environment of frequent electricity consumption, our electricity consumption is also gradually increasing. However, in our current power generation projects, thermal power generation produces a large amount of carbon dioxide, indicating excessive carbon emissions. Renewable energy generation is not yet widely available. In the current era of promoting green electricity, we need to convert our current power generation to energy storage methods to adapt to the current green environment. However, current power storage methods lack effective energy storage planning, and those that do exist are not intelligent enough and do not meet actual conditions. Summary of the Invention

[0003] Therefore, the embodiments of the present invention provide a method and system for energy storage investment planning based on electrification improvement, which improves the intelligence and scientific level of energy storage planning.

[0004] In order to solve the above problems, the present invention provides an energy storage investment planning method based on electrification improvement, which includes: querying the weather system, recording daily carbon emissions, and integrating data to establish an emission database; obtaining carbon emissions in the first historical period and recording them as the first emissions; obtaining carbon emissions in the second historical period and recording them as the second emissions, and the time of the second historical period is earlier than the first historical period; subtracting the first emissions from the second emissions to obtain a first difference; obtaining carbon emissions in the third historical period and recording them as the third emissions; obtaining carbon emissions in the fourth historical period and recording them as the fourth emissions, and the fourth historical period is earlier than the third historical period, and the third historical period is earlier than the third historical period. in the second historical period; subtract the third emissions from the fourth emissions to obtain a second difference; compare the first difference with the second difference to obtain a first comparison result, and determine whether the energy storage ratio needs to be adjusted based on the first comparison result; if it is determined that the energy storage ratio needs to be adjusted, then the carbon emissions in the fifth period in the future are predicted based on the first emissions, the second emissions, the third emissions, and the fourth emissions, and recorded as the fifth emissions; adjust the power generation ratio of thermal power generation and renewable energy power generation based on the first comparison result and the fifth emissions; if it is determined that the energy storage ratio does not need to be adjusted, obtain the weather conditions in the first time period in the future, and make a first adjustment to thermal power generation and renewable energy power generation based on the weather conditions.

[0005] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting up an emissions database to facilitate subsequent data query and recording, the convenience of data processing is improved, and at the same time, the carbon emissions in two historical periods are subtracted, and the carbon emissions in two earlier historical periods are obtained to make a difference, and the two differences are compared to determine whether the energy storage ratio needs to be adjusted. In this way, the carbon emissions in the four periods can be more clearly understood, and the increase in carbon emissions in the two periods can be reflected by the difference, and the changes in carbon emissions in the four periods can be better reflected by comparing the two differences, which can better provide a more practical data basis for the subsequent adjustment of the energy storage ratio, making the adjustment more intelligent and scientific. It also predicts the carbon emissions in the fifth cycle in the future based on the four emissions when adjusting the energy storage ratio, and then adjusts the ratio of thermal power generation and renewable energy power generation based on these data. In this way, the adjustment of the ratio is more in line with the actual situation, and the adjustment of the ratio is more scientific, which reduces carbon emissions as much as possible without affecting the use, and improves the greenness of the environment. At the same time, when there is no need to adjust the energy storage ratio, the weather conditions are obtained to make the first adjustment to the power generation ratio of thermal power generation and renewable energy power generation, making the overall adjustment process more perfect, and can better adjust to the actual situation, thereby improving practicality and intelligence.

[0006] In one example of the present invention, the third historical cycle is a corresponding time period of the year before the first historical cycle; and the fourth historical cycle is a corresponding time period of the year before the second historical cycle.

[0007] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the historical third cycle and the historical fourth cycle as the corresponding cycles of the year before the historical first cycle and the historical second cycle, the increase in carbon emissions in the two cycles can be obtained more quickly through the corresponding cycles, so as to better respond to the current situation and make more scientific and reasonable energy storage adjustments, thereby improving the practicality and intelligence of the adjustments.

[0008] In one embodiment of the present invention, the first difference and the second difference are compared to obtain a comparison result, and judging whether the energy storage ratio needs to be adjusted based on the comparison result also includes: if the first difference is greater than the second difference, judging that the energy storage ratio needs to be adjusted; if the first difference is less than or equal to the second difference, judging that the energy storage ratio does not need to be adjusted.

[0009] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by adjusting the energy storage ratio when the first difference is greater than the second difference, it means that the current carbon emissions have exceeded the carbon emissions in the same period, and it is necessary to reduce the proportion of thermal power generation to reduce carbon emissions, thereby improving the greenness of the environment. In this way, it is possible to more quickly judge whether the current carbon emissions are excessive, making subsequent adjustments more convenient and quicker.

[0010] In one example of the present invention, adjusting the power generation ratio of thermal power generation and renewable energy power generation based on the first comparison result and the fifth emission amount also includes: obtaining all dates within the future fifth cycle; querying the emission database to obtain all carbon emissions in the historical time period corresponding to the future fifth cycle, and taking the average to obtain the sixth emission amount; comparing the fifth emission amount and the sixth emission amount to obtain a second comparison result, and adjusting the power generation ratio of thermal power generation and renewable energy power generation based on the second comparison result.

[0011] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the carbon emissions in the fifth cycle in the future and the average value of the corresponding carbon emissions in the historical cycle, and then comparing the two, the power generation ratio of thermal power generation and new energy power generation is adjusted. In this way, the carbon emissions in the fifth cycle in the future can be controlled, and by comparing the predicted value and the historical value, it can be more convenient to judge whether the carbon emissions in the fifth cycle are too high, which improves the accuracy and convenience of the judgment and makes subsequent adjustments more reasonable and scientific.

[0012] In one example of the present invention, adjusting the power generation ratio of thermal power generation and renewable energy power generation according to the second comparison result also includes: if the fifth emission amount is greater than the sixth emission amount, subtracting the fifth emission amount from the sixth emission amount to obtain a third difference; comparing the third difference with the first threshold to obtain a third comparison result, and making a first adjustment to the power generation ratio of thermal power generation and renewable energy power generation according to the third comparison result; if the fifth emission amount is less than or equal to the sixth emission amount, controlling the power generation ratio of thermal power generation to decrease by a first value, and controlling the power generation ratio of renewable energy power generation to increase by a second value.

[0013] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting it to be when the fifth emission amount is greater than the sixth emission amount, a third difference is obtained by taking the difference, and the third difference is compared with the first threshold, and then a first adjustment is made to the power generation ratio of thermal power generation and new energy power generation. When the fifth emission amount is greater than the sixth emission amount, it indicates that the current carbon emissions are too high and need to be adjusted. When the fifth emission amount is less than or equal to the sixth emission amount, although it is not higher than the historical value, it is also relatively high. In this case, the proportion of thermal power generation is reduced and the proportion of new energy power generation is increased, thereby reducing the overall carbon emissions and improving the greenness of the environment. In addition, this adjustment method is faster and more scientific.

[0014] In an example of the present application, the first adjustment of the power generation proportions of thermal power generation and new energy power generation according to the third comparison result further comprises: if the third difference is greater than the first threshold value, further reducing the power generation proportion of thermal power generation by a first value and further increasing the power generation proportion of new energy power generation by a second value; and if the third difference is less than or equal to the first threshold value, monitoring the carbon emissions in the future fifth period in real time.

[0015] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: by setting that when the third difference is greater than the first threshold value, the proportion of thermal power generation is further reduced by a value, and the proportion of new energy power generation is further increased by a second value, when the third difference is too large, it indicates that the carbon emissions in the fifth period are too high and need to be further reduced, through this way, the proportions of thermal power generation and new energy power generation can be more quickly regulated and controlled, and it is more in line with the actual situation and has better intelligent degree, and when the third difference is less than or equal to the first threshold value, the fifth period is monitored in real time, which ensures power supply while preventing the carbon emissions from being too high, and improves the perfection degree of overall control.

[0016] In an example of the present application, if it is judged that the energy storage proportion does not need to be adjusted, the weather condition in the future first time period is obtained, and the first adjustment of thermal power generation and new energy power generation according to the weather condition further comprises: judging whether there is a sunny day in the region where the power plant is located in the future first time period; if it is judged that there is, increasing the power generation proportion of new energy power generation by a third value on sunny days; and if it is judged that there is not, making a pre-warning adjustment of thermal power generation and new energy power generation.

[0017] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: by setting whether there is a sunny day in the region where the power plant is located in the future first time period, and controlling new energy power generation and thermal power generation according to the sunny day, by increasing the proportion of new energy power generation on sunny days, the carbon emissions can be further reduced, and the environment can be better protected.

[0018] In an example of the present application, if it is judged that there is not, making a pre-warning adjustment of thermal power generation and new energy power generation further comprises: if it is a sunny day, increasing the power generation proportion of new energy power generation by a fourth value; and if it is a weather other than sunny day, applying for power scheduling of power plants outside the region.

[0019] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting that when there is no sunny weather in the first time period in the future, the proportion of renewable energy power generation will be increased when it is sunny on that day, thereby accumulating more electricity through renewable energy power generation, so that there is no need to rely too much on thermal power generation when there is no sunny weather in the future, thereby reducing carbon emissions. When it is not sunny on that day, electricity is dispatched to power plants outside the region, making the current environment greener.

[0020] The present invention also provides an energy storage investment planning system based on electrification improvement. The energy storage investment planning system is used to implement any of the energy storage investment planning methods mentioned above. The energy storage investment planning system includes: an acquisition module, which is used to obtain carbon emissions and weather conditions; a calculation and comparison module, which is used to calculate carbon emissions and compare the difference; and a control module, which is used to control the power generation ratio of thermal power generation and new energy power generation.

[0021] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting up an acquisition module to obtain weather conditions and carbon emissions, the acquisition is made more convenient and quick, and can better provide data support for subsequent judgments. At the same time, by setting up a calculation and comparison module to compare the differences, the comparison process is made faster and more accurate, and the overall intelligence level is higher. The control module is also set to control the power generation ratio of thermal power generation and new energy power generation, making the control more convenient and quick.

[0022] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0023] (1) By setting up an emission database to facilitate subsequent data query and recording, the convenience of data processing is improved. At the same time, the carbon emissions in two historical periods are used to make a difference, and the carbon emissions in two earlier historical periods are obtained to make a difference. The two differences are compared to determine whether the energy storage ratio needs to be adjusted. In this way, the carbon emissions in the four periods can be more clearly understood. At the same time, the increase in carbon emissions in the two periods can be reflected by the difference, and the change in carbon emissions in the four periods can be better reflected by comparing the two differences. This can provide a more practical data basis for the subsequent adjustment of the energy storage ratio, making the adjustment more intelligent and scientific. In addition, when adjusting the energy storage ratio, the system predicts the carbon emissions in the fifth cycle based on the four emissions, and then adjusts the ratio of thermal power generation and renewable energy power generation based on these data. This method makes the adjustment of the ratio more in line with the actual situation, and also makes the adjustment of the ratio more scientific, reducing carbon emissions as much as possible without affecting the use, and improving the greenness of the environment. At the same time, when there is no need to adjust the energy storage ratio, the weather conditions are obtained to make the first adjustment to the power generation ratio of thermal power generation and renewable energy power generation, making the overall adjustment process more perfect, and can better adjust to the actual situation, improving practicality and intelligence.

[0024] (2) By setting the time when there is no sunny weather in the first time period in the future, the proportion of renewable energy power generation will be increased when it is sunny on that day, thereby accumulating more electricity through renewable energy power generation, so that there is no need to rely too much on thermal power generation when there is no sunny weather in the future, reducing carbon emissions. When it is not sunny on that day, electricity will be dispatched to power plants outside the region, making the current environment greener. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] To make the above-mentioned objectives, features, and advantages of the present invention more clearly understood, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0031] [First embodiment]

[0032] See also Figure 1 The present invention provides an energy storage investment planning method based on electrification improvement, the energy storage investment planning method comprising:

[0033] Step S100: query the weather system, record daily carbon emissions, and integrate the data to establish an emissions database; obtain the carbon emissions in the first historical period and record them as the first emissions;

[0034] Step S200: Obtain the carbon emissions in the second historical period and record them as the second emissions, and the time of the second historical period is earlier than the first historical period; subtract the first emissions from the second emissions to obtain a first difference; obtain the carbon emissions in the third historical period and record them as the third emissions; obtain the carbon emissions in the fourth historical period and record them as the fourth emissions, and the fourth historical period is earlier than the third historical period, and the third historical period is earlier than the second historical period;

[0035] Step S300: Subtracting the third emission amount from the fourth emission amount to obtain a second difference; comparing the first difference with the second difference to obtain a first comparison result, and determining whether the energy storage ratio needs to be adjusted based on the first comparison result;

[0036] Step S310: If it is determined that the energy storage ratio needs to be adjusted, the carbon emissions in the fifth period in the future are predicted based on the first emission amount, the second emission amount, the third emission amount, and the fourth emission amount, and recorded as the fifth emission amount; and the power generation ratio of thermal power generation and renewable energy power generation is adjusted based on the first comparison result and the fifth emission amount.

[0037] Step S320: If it is determined that the energy storage ratio does not need to be adjusted, the weather conditions in the first future time period are obtained, and a first adjustment is made to thermal power generation and renewable energy power generation according to the weather conditions.

[0038] Specifically, when carrying out energy storage investment planning, the daily carbon emissions of all power generation facilities in the target area are recorded, the daily carbon emissions of different power generation facilities are classified and recorded, and an emissions database is established based on these data. The emissions database also includes all carbon emissions data of all power generation facilities that have been recorded in history.

[0039] Furthermore, when planning energy storage, the carbon emissions for the first and second historical periods are obtained to obtain first and second emissions. The first and second historical periods are manually defined periods, which can be the week and two weeks before the current day, respectively, and can be adjusted based on actual conditions. The first and second emissions are then subtracted to obtain a first difference.

[0040] Furthermore, the carbon emissions of the historical third and fourth periods corresponding to the historical first and second periods are obtained, where the corresponding time periods are the corresponding time periods of the previous year, and then the third emissions and the fourth emissions are obtained, and the third emissions and the fourth emissions are subtracted to obtain a second difference, and the first difference is compared with the second difference.

[0041] Furthermore, when the first difference is greater than the second difference, the carbon emissions for the fifth period in the future are predicted based on the first, second, third, and fourth emissions. Specifically, the formula is (first emissions + second emissions) / (third emissions + fourth emissions) * first emissions = fifth emissions. This method can quickly predict the fifth emissions, and a coefficient is obtained by multiplying the coefficient by the carbon emissions in the most recent time period to obtain the predicted value. This predicted value is more realistic, making subsequent energy storage allocation more reasonable.

[0042] Furthermore, after obtaining the fifth emission amount, all carbon emissions in the historical time period corresponding to the future fifth cycle are obtained, and the average is taken to obtain the sixth emission amount. Based on the comparison results of the two, the power generation ratio of thermal power generation and renewable energy power generation is adjusted, that is, the electricity generated by the two is correspondingly allocated for energy storage.

[0043] Preferably, an emission database is set up to facilitate subsequent data query and recording, thereby improving the convenience of data processing. At the same time, the carbon emissions in two historical periods are used to make a difference, and the carbon emissions in two earlier historical periods are obtained to make a difference, and the two differences are compared to determine whether the energy storage ratio needs to be adjusted. In this way, the carbon emissions in the four periods can be more clearly understood, and the increase in carbon emissions in the two periods can be reflected by the difference. The comparison of the two differences can better reflect the changes in carbon emissions in the four periods, and thus can better provide a more practical data basis for the subsequent adjustment of the energy storage ratio, making the adjustment more intelligent and scientific. It also predicts the carbon emissions in the fifth cycle in the future based on the four emissions when adjusting the energy storage ratio, and then adjusts the ratio of thermal power generation and renewable energy power generation based on these data. In this way, the adjustment of the ratio is more in line with the actual situation, and the adjustment of the ratio is more scientific, which reduces carbon emissions as much as possible without affecting the use, and improves the greenness of the environment. At the same time, when there is no need to adjust the energy storage ratio, the weather conditions are obtained to make the first adjustment to the power generation ratio of thermal power generation and renewable energy power generation, making the overall adjustment process more perfect, and can better adjust to the actual situation, thereby improving practicality and intelligence.

[0044] Specifically, the third historical cycle is the corresponding time period of the year before the first historical cycle; the fourth historical cycle is the corresponding time period of the year before the second historical cycle.

[0045] Preferably, by setting the third historical cycle and the fourth historical cycle as corresponding cycles of the year before the first historical cycle and the second historical cycle, the increase in carbon emissions in the two cycles can be obtained more quickly through the corresponding cycles, so as to better respond to the current situation and make more scientific and reasonable energy storage adjustments, thereby improving the practicality and intelligence of the adjustments.

[0046] Specifically, the first difference and the second difference are compared to obtain a comparison result, and judging whether the energy storage ratio needs to be adjusted according to the comparison result also includes: if the first difference is greater than the second difference, judging that the energy storage ratio needs to be adjusted; if the first difference is less than or equal to the second difference, judging that the energy storage ratio does not need to be adjusted.

[0047] Preferably, by setting the energy storage ratio to be adjusted when the first difference is greater than the second difference, it means that the current carbon emissions have exceeded the carbon emissions in the same period, and it is necessary to reduce the proportion of thermal power generation to reduce carbon emissions, thereby improving the greenness of the environment. In this way, it is possible to more quickly determine whether the current carbon emissions are excessive, making subsequent adjustments more convenient and quicker.

[0048] Specifically, adjusting the power generation ratio of thermal power generation and renewable energy power generation based on the first comparison result and the fifth emission amount also includes: obtaining all dates in the future fifth cycle; querying the emission database to obtain all carbon emissions in the historical time period corresponding to the future fifth cycle, and taking the average to obtain the sixth emission amount; comparing the fifth emission amount and the sixth emission amount to obtain a second comparison result, and adjusting the power generation ratio of thermal power generation and renewable energy power generation based on the second comparison result.

[0049] Preferably, the carbon emissions in the fifth period in the future and the average value of the corresponding carbon emissions in the historical period are obtained, and then the two are compared to adjust the power generation ratio of thermal power generation and new energy power generation. In this way, the carbon emissions in the fifth period in the future can be controlled, and by comparing the predicted value and the historical value, it can be more convenient to judge whether the carbon emissions in the fifth period are too high, thereby improving the accuracy and convenience of the judgment and making subsequent adjustments more reasonable and scientific.

[0050] Specifically, adjusting the power generation ratio of thermal power generation and renewable energy power generation according to the second comparison result also includes: if the fifth emission amount is greater than the sixth emission amount, subtracting the fifth emission amount from the sixth emission amount to obtain a third difference; comparing the third difference with the first threshold to obtain a third comparison result, and making a first adjustment to the power generation ratio of thermal power generation and renewable energy power generation according to the third comparison result; if the fifth emission amount is less than or equal to the sixth emission amount, controlling the power generation ratio of thermal power generation to decrease by a first value, and controlling the power generation ratio of renewable energy power generation to increase by a second value.

[0051] Specifically, the first value, the second value, and the first threshold are artificially defined values ​​and can be adjusted according to actual conditions.

[0052] Preferably, by setting it to be when the fifth emission amount is greater than the sixth emission amount, a third difference is obtained by taking the difference, and the third difference is compared with the first threshold value, and then a first adjustment is made to the power generation ratio of thermal power generation and new energy power generation. When the fifth emission amount is greater than the sixth emission amount, it means that the current carbon emissions are too high and need to be adjusted. When the fifth emission amount is less than or equal to the sixth emission amount, although it is not higher than the historical value, it is also relatively high. In this case, the proportion of thermal power generation is reduced and the proportion of new energy power generation is increased, thereby reducing the overall carbon emissions and improving the greenness of the environment. In addition, this adjustment method is faster and more scientific.

[0053] Specifically, the first adjustment of the power generation ratio of thermal power generation and renewable energy power generation based on the third comparison result also includes: if the third difference is greater than the first threshold, controlling the power generation ratio of thermal power generation to further reduce the first value, and controlling the power generation ratio of renewable energy power generation to further increase the second value; if the third difference is less than or equal to the first threshold, real-time monitoring of carbon emissions in the future fifth cycle.

[0054] Preferably, by setting the third difference to be greater than the first threshold, the proportion of thermal power generation is further reduced, and the proportion of renewable energy power generation is further increased by the second value. When the third difference is too large, it means that the carbon emissions in the fifth cycle are too high and need to be further reduced. In this way, the proportion of thermal power generation and renewable energy power generation can be regulated more quickly, and it is more in line with reality and more intelligent. When the third difference is less than or equal to the first threshold, the fifth cycle is monitored in real time to ensure power supply while preventing carbon emissions from being too high, thereby improving the perfection of the overall control.

[0055] Specifically, if it is determined that the energy storage ratio does not need to be adjusted, the weather conditions in the first time period in the future are obtained, and the first adjustment of thermal power generation and renewable energy power generation is made according to the weather conditions. It also includes: determining whether there will be sunny days in the area where the power station is located in the first time period in the future; if it is determined that there will be sunny days, the power generation ratio of renewable energy power generation is controlled to increase by a third value on sunny days; if it is determined that there will be no sunny days, early warning adjustments will be made to thermal power generation and renewable energy power generation.

[0056] Specifically, the third value and the first future time period are both manually defined data and can be adjusted according to actual conditions.

[0057] Preferably, by setting up to judge whether there will be sunny days in the area where the power plant is located in the first time period in the future, and controlling the new energy power generation and thermal power generation according to the sunny days, by increasing the proportion of new energy power generation on sunny days, carbon emissions can be further reduced and the environment can be better protected.

[0058] Specifically, if it is judged that it does not exist, the early warning adjustment of thermal power generation and renewable energy power generation also includes: if it is sunny on that day, the power generation proportion of renewable energy power generation is controlled to increase the fourth value; if the weather on that day is other than sunny, power generation stations outside the area are applied for power dispatch.

[0059] Preferably, by setting it so that when there is no sunny weather in the first time period in the future, the proportion of renewable energy power generation is increased when it is sunny on that day, thereby accumulating more electricity through renewable energy power generation, so that there is no need to rely too much on thermal power generation for power supply when there is no sunny weather in the future, thereby reducing carbon emissions. When it is not sunny on that day, electricity is dispatched to power plants outside the region, making the current environment greener.

At the same time, a calculation and comparison module 120 is set to compare the differences, making the comparison process faster and more accurate, and making the overall intelligence higher.
