Technical Field

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

[0002] With the development of science and technology, our lives are becoming more and more convenient. In the current environment of frequent electricity consumption, our electricity consumption is also gradually increasing. In our current power generation projects, thermal power generation will produce a large amount of carbon dioxide, that is, carbon emissions are too high, and new energy power generation methods are not yet popular enough. At the moment of advocating green electricity, we need to convert the current power generation energy storage method to adapt to the current green environment, but the current power storage method does not have a good energy storage planning method, and the existing one is not intelligent enough, and it is not in line with the actual situation. 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 scientificity of energy storage planning.

[0004] 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 cycle; subtract the third emission from the fourth emission 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 according to the first comparison result; if it is determined that the energy storage ratio needs to be adjusted, then the carbon emissions in the fifth cycle 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 new energy power generation according to 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 new energy power generation according to the weather conditions.

[0005] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting up an emission 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 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, and the comparison of the two differences can better reflect the changes in carbon emissions in the four periods, thereby providing a more realistic data basis for the subsequent adjustment of the energy storage ratio, making the adjustment more intelligent and scientific. It is also set to predict the carbon emissions in the fifth cycle in the future based on the four emissions when adjusting the energy storage ratio, and then adjust 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, improves the greenness of the environment, and 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; 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 previous year of 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 cycle, 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 example 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 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.

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

[0011] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting the average value of the carbon emissions in the fifth cycle in the future and 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 the 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 prior art, the technical effect achieved by adopting this technical solution is as follows: when the fifth emission is greater than the sixth emission, a third difference is obtained by 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 is greater than the sixth emission, it indicates that the current carbon emissions are too high and need to be adjusted. When the fifth emission is less than or equal to the sixth emission, 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. Moreover, this adjustment method is faster and more scientific.

[0014] In one example of the present invention, 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, the power generation ratio of thermal power generation is controlled to further decrease by the first value, and the power generation ratio of renewable energy power generation is controlled to further increase by the second value; if the third difference is less than or equal to the first threshold, the carbon emissions in the future fifth period are monitored in real time.

[0015] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: 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 adjusted 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.

[0016] In one example of the present invention, if it is determined that there is no need to adjust the energy storage ratio, 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, which 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 to 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.

[0017] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: 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 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.

[0018] In one example of the present invention, 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 a sunny day, the power generation ratio of renewable energy power generation is controlled to increase the fourth value; if the weather on that day is other than sunny, then apply for power generation outside the area for power dispatch.

[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 new energy power generation will be increased when it is sunny on that day, so that more electricity can be accumulated through new 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 as described above, the energy storage investment planning system includes: an acquisition module, the acquisition module is used to acquire carbon emissions and weather conditions; a calculation and comparison module, the calculation and comparison module is used to calculate carbon emissions and compare the difference; a control module, the control module 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 as follows: by setting up an acquisition module to obtain weather conditions and carbon emissions, the acquisition is made more convenient and quicker, and better data support can be provided for subsequent judgments. At the same time, by setting up a calculation comparison module to compare the difference, the comparison process is made faster and more accurate, and the overall intelligence level is higher. In addition, by setting up a control module to control the power generation ratio of thermal power generation and new energy power generation, the control is made more convenient and quick.

[0022] After adopting the technical solution of the present invention, the following technical effects can be achieved: (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. The comparison of the two differences can better reflect the changes in carbon emissions in the four periods, and thus provide a more realistic data basis for the subsequent adjustment of the energy storage ratio, making the adjustment more intelligent and scientific. It is also set to predict the carbon emissions in the fifth cycle in the future according to the four emissions when adjusting the energy storage ratio, and then adjust the ratio of thermal power generation and renewable energy power generation according to 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 for the actual situation, improving the practicality and intelligence. (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, 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] [First embodiment] See also Figure 1 The present invention provides an energy storage investment planning method based on electrification promotion, and the energy storage investment planning method includes: Step S100: query the weather system, record the 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; 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; Step S300: subtract the third emission amount from the fourth emission amount 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 according to the first comparison result; 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; the power generation ratio of thermal power generation and new energy power generation is adjusted based on the first comparison result and the fifth emission amount; 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.

[0027] 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.

[0028] Furthermore, when planning energy storage, the carbon emissions in the first historical cycle and the second historical cycle are obtained to obtain the first emission and the second emission, wherein the first historical cycle and the second historical cycle are artificially defined cycles, which can be the week before the day and the two weeks before the day, and can be adjusted according to actual conditions. Then, the first emission and the second emission are subtracted to obtain the first difference.

[0029] 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.

[0030] 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 emissions, the second emissions, the third emissions and the fourth emissions. Specifically, it can be (first emissions + second emissions) / (third emissions + fourth emissions) * first emissions = fifth emissions. In this way, the fifth emissions can be quickly predicted, and a coefficient is obtained through the proportion of the same period. The coefficient multiplied by the carbon emissions in the most recent time period is the predicted value. The predicted value is more in line with reality, making the subsequent energy storage allocation more reasonable.

[0031] Furthermore, after obtaining the fifth emission, 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. Based on the comparison results of the two, the power generation ratio of thermal power generation and new energy power generation is adjusted, that is, the electricity generated by the two is correspondingly allocated for energy storage.

[0032] 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 provide a more realistic data basis for the subsequent adjustment of the energy storage ratio, making the adjustment more intelligent and scientific. It is also set to predict the carbon emissions in the fifth cycle in the future based on the four emissions when adjusting the energy storage ratio, and then adjust 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, improves the greenness of the environment, and 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.

[0033] 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.

[0034] Preferably, by setting the third historical cycle and the fourth historical cycle as corresponding cycles of the previous year of the first historical cycle and the second historical cycle, the increase in carbon emissions within the two cycles can be obtained more quickly through the corresponding cycle, 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 adjustment.

[0035] 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.

[0036] 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.

[0037] Specifically, adjusting the power generation ratio of thermal power generation and renewable energy power generation according to 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 the second comparison result, and adjusting the power generation ratio of thermal power generation and renewable energy power generation according to the second comparison result.

[0038] 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, which improves the accuracy and convenience of the judgment and makes the subsequent adjustments more reasonable and scientific.

[0039] 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.

[0040] Specifically, the first value, the second value and the first threshold are artificially defined values ​​and can be adjusted according to actual conditions.

[0041] Preferably, by setting it to be when the fifth emission amount is greater than the sixth emission amount, a third difference is obtained by 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 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. Moreover, this adjustment method is faster and more scientific.

[0042] Specifically, the first adjustment of the power generation ratio of thermal power generation and renewable energy power generation according to 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.

[0043] 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 practical 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.

[0044] Specifically, if it is determined that there is no need to adjust the energy storage ratio, 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, which 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.

[0045] Specifically, the third value and the first future time period are both artificially defined data and can be adjusted according to actual conditions.

[0046] Preferably, by setting up to determine whether there will be sunny days in the area where the power plant is located within the first time period in the future, and controlling the renewable energy power generation and thermal power generation according to the sunny days, by increasing the proportion of renewable energy power generation on sunny days, carbon emissions can be further reduced and the environment can be better protected.

[0047] 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 a sunny 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, apply for power generation outside the area to carry out power dispatch.

[0048] 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, so that more electricity can be accumulated 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.
