Description

Technical Field

[0001] The present invention relates to the technical field of energy storage management, and in particular to an industrial and commercial energy storage system management optimization method and system. Background Art

[0002] Energy storage system is a part of the object or space range that is demarcated to determine the research object, including the input and output of energy and matter, energy conversion and storage equipment; energy storage system stores energy through media or equipment and releases it when needed. Common energy storage methods include batteries, inductors and capacitors; for example, battery energy storage system consists of batteries and parallel voltage converters, and has the ability to quickly adjust the power exchange between the AC system.

[0003] Existing methods for optimizing the management of energy storage systems are usually improvements in the monitoring efficiency of battery energy storage. By analyzing the environment in which the energy storage battery is located and the actual capacity of the energy storage battery, the self-discharge rate of the battery pack is predicted, thereby improving the detection efficiency of battery energy storage. Although this improvement method can solve the problem that the self-discharge efficiency of the battery pack cannot be understood when the battery pack is shelved for a long time, when the battery pack is used in a frequently used working scenario, such as an industrial and commercial power unit, if only the detection of the self-discharge efficiency of the battery pack is optimized, it will result in the battery pack frequently charging and discharging. The state between the charging and discharging of the battery pack cannot be effectively monitored, resulting in the self-discharge efficiency of the battery pack being within the normal range, but the charging efficiency or power supply efficiency cannot meet the standard, resulting in the problem that the power unit cannot be effectively powered. For example, in the patent application No. CN11631698 The patent application of 8A discloses a method for optimizing the management of an energy storage system based on the prediction of the self-discharge rate of a battery pack. This solution analyzes the influence of the storage environment temperature, storage environment humidity, and actual battery capacity on the self-discharge rate of the energy storage battery, so as to solve the technical problem of being able to know the current self-discharge rate of the battery pack at any time when the battery pack is not working for a long time. Other improvements in the management optimization of energy storage systems are usually improvements in the service life of the battery, which still cannot solve the problem that when the battery pack is used in frequently used working scenarios, such as industrial and commercial power users, the state between the charging and discharging of the battery pack cannot be effectively monitored, resulting in the self-discharge efficiency of the battery pack being within the normal range, but the charging efficiency or power supply efficiency cannot meet the standard, resulting in the problem that the power user cannot be effectively powered. In view of this, it is necessary to improve the existing management optimization method for energy storage systems. Summary of the invention

[0048] In the specific implementation process, in this embodiment, the energy storage battery used for the industrial and commercial system can be specifically: such as the energy storage battery used to power all shops in the commercial street, the energy storage battery used to power all factory equipment in the factory, or the energy storage battery used to power all company shops in the office building; because the power consumption of the above-mentioned power-consuming units is usually high, the power supply and discharge of the energy storage battery will be more frequent, which is suitable for the improved method in this embodiment;

[0049] A plane rectangular coordinate system is established, which is recorded as the power consumption analysis coordinate system, wherein the unit of the X-axis of the power consumption analysis coordinate system is time, and the unit of the Y-axis is power; the acquired power consumption data is divided into the power consumption data of the whole day, and recorded as the whole day data ZY1 to the whole day data ZY n , where the whole day is from 0:00 to 24:00 in one day;

[0051] In the specific implementation process, for example, in a data processing, the power consumption analysis coordinate system is obtained as follows: Figure 4 As shown, curve CD is the charging curve, and curve FD is the discharging curve. By analysis, we can get: Figure 4 Point T in is the charging and discharging point, and the curve CD between the straight line CD1 and the straight line CD2 is the charging and discharging period; through analysis, it can be obtained that 0 to H1 is the charging period, H1 to H2 is the charging and discharging period, and H2 to 24 is the discharging period;

[0058] The charging efficiency analysis is as follows: for any charging analysis unit, the charging rate of the energy storage battery and the real-time power consumption of the charging analysis unit when the charging analysis unit is in working time are obtained; for any second of the working time of the charging analysis unit, the ratio of the charging rate of the energy storage battery to the instantaneous power consumption of the charging analysis unit in that second is recorded as the charging impact ratio; the charging impact ratio corresponding to each second of the working time of the charging analysis unit is obtained, and the interval formed by all the charging impact ratios is recorded as the charging ratio interval;

[0059] In the specific implementation process, for example, for any second α of the working time of the charging analysis unit, the charging rate of the energy storage battery within second α is 1C, and the instantaneous power consumption of the charging analysis unit within second α is 10kw; in the calculation of this embodiment, the instantaneous power consumption of the charging analysis unit is used for calculation. The value is uniformly switched to kw for calculation. For example, when the charging rate is 1C and the instantaneous power consumption is 10kw, the charging influence ratio during calculation is 1 to 10, that is, 0.1; by obtaining the charging influence ratio and then obtaining the charging ratio interval, the relationship between the power consumption of the industrial and commercial units and the charging rate of the energy storage battery during the charging process of the energy storage battery can be obtained, which is helpful for providing data support for the subsequent analysis of the state between charging and discharging of the battery pack;

[0060] The collection of charging ratio intervals corresponding to all charging analysis units is recorded as the charging influence interval.

[0061] The whole day data ZY of the time period corresponding to the discharge curve in the high-efficiency discharge period is recorded as the discharge analysis data; the industrial and commercial units recorded by the discharge analysis data are recorded as the discharge analysis units, and the discharge analysis units perform discharge efficiency analysis;

[0062] The discharge efficiency analysis is as follows: for any discharge analysis unit, a plane rectangular coordinate system is established, which is recorded as the discharge analysis coordinate system, wherein the unit of the X-axis of the discharge analysis coordinate system is time, and the working time of the discharge analysis unit is marked on the X-axis; when the unit of the Y-axis is power consumption, a corresponding curve is drawn in the discharge analysis coordinate system based on the corresponding power consumption of the discharge analysis unit during the working time, and recorded as the discharge analysis curve; when the unit of the Y-axis is the discharge rate, a corresponding curve is drawn in the discharge analysis coordinate system based on the discharge rate of the energy storage battery during the working time of the discharge analysis unit, and recorded as the battery discharge curve;

[0063] In the specific implementation process, for example, during a data processing, the discharge analysis coordinate system is obtained as follows: Figure 3 As shown, curve DF is the battery discharge curve, and curve FQ is the discharge analysis curve; then for ZZ1 and ZZ2 corresponding to time point A, the value of ZZ2 divided by ZZ1 is recorded as the discharge influence ratio;

[0064] For any time point A within the working time of the discharge analysis unit, the ratio of the ordinate corresponding to the point whose abscissa is time point A in the battery discharge curve to the ordinate corresponding to the point whose abscissa is time point A in the discharge analysis curve is recorded as the discharge influence ratio;

[0065] Obtain the discharge impact ratios of all time points within the working time of the discharge analysis unit, record the interval formed by all discharge impact ratios as the discharge ratio interval, record the time point corresponding to the minimum value of the discharge impact ratio as the low-limit point, and mark the vertical coordinate corresponding to the point whose horizontal coordinate is the low-limit point in the discharge analysis curve as the low-limit electricity; draw straight lines parallel to the Y axis from the leftmost point and the rightmost point of the discharge analysis curve, respectively, and record them as the left boundary line and the right boundary line; record the area between the left boundary line, the right boundary line, the discharge analysis curve and the X axis as the low-limit electricity;

[0066] In the specific implementation process, by obtaining the discharge impact ratio and then obtaining the discharge ratio interval, the relationship between the power consumption of industrial and commercial units and the charging rate of the energy storage battery during the discharge of the energy storage battery can be obtained, which is helpful for providing data support for the subsequent analysis of the state between the charging and discharging of the battery pack. At the same time, the low-limit power and the low-limit power are obtained, and the minimum instantaneous power supply and the minimum total power supply can be obtained when powering the industrial and commercial units, so as to prevent the actual operation of the industrial and commercial units from being affected due to the small power supply during the power supply period.

[0067] Perform discharge efficiency analysis on all discharge analysis units, record the collection of all discharge ratio intervals as the discharge influence interval, record the minimum value of all low-limit electricity as the discharge minimum limit, and record the minimum value of all low-limit electricity as the discharge minimum limit.

[0068] The energy storage management optimization module is used to analyze the charge-discharge balance period, and obtain the charge-discharge switching interval based on the analysis results, the charge influence interval and the discharge influence interval; manage the energy storage system based on the charge-discharge switching interval, the minimum discharge limit and the minimum discharge limit;

[0069] The energy storage management optimization module includes an energy storage management optimization unit, which is configured with an energy storage management optimization strategy. The energy storage management optimization strategy includes: recording the full-day data ZY in the time period corresponding to the charging period or the discharging period in the charging and discharging balance period as the charging and discharging analysis data; recording the industrial and commercial units recorded in the charging and discharging analysis data as the charging and discharging analysis units, and obtaining the low-limit electricity corresponding to all the charging and discharging analysis units based on the discharge efficiency analysis. When the low-limit electricity corresponding to all the charging and discharging analysis units is greater than or equal to the minimum discharge limit, the minimum discharge limit is kept unchanged;

[0070] When the low-limit electricity quantity corresponding to any charge-discharge analysis unit is less than the minimum discharge limit, the minimum value of the low-limit electricity quantities corresponding to all charge-discharge analysis units is recorded as the minimum discharge limit, and the low-limit point corresponding to the minimum discharge limit at this time is recorded as the minimum limit point, and the discharge impact ratio corresponding to the minimum limit point is recorded as the discharge change ratio;

[0071] In the specific implementation process, for example, during a data processing, the minimum value of the low-limit electricity corresponding to all charge and discharge analysis units is 200 degrees, and the minimum discharge limit is 210 degrees. Then 200 degrees is recorded as the minimum discharge limit, and the low limit point corresponding to 200 degrees is recorded as the minimum limit point. At this time, the discharge influence ratio corresponding to the minimum limit point is 0.5; then 0.5 is set as the discharge change ratio;

[0072] Use the interval construction algorithm to obtain the charge and discharge switching interval. The interval construction algorithm is: , where when γ is max, F is the maximum value of the charge-discharge switching interval, and when γ is min, F is the minimum value of the charge-discharge switching interval; f min is the minimum value of the charging impact interval, f max is the maximum value of the charging impact interval, g min is the minimum value of the discharge influence interval, g max is the maximum value of the discharge influence interval, f0 is the discharge change ratio;

[0073] In the specific implementation process, for example, in a data processing, the charging influence interval is [0.01, 0.5], the discharging influence interval is [0.2, 0.8], and the discharge change ratio is 0.5; then, by calculation, the charging and discharging switching interval is [-0.395, 0.15]; by obtaining the charging and discharging switching interval, the data corresponding to the normal state between charging and discharging of the battery pack can be extracted, which is helpful for monitoring the state between charging and discharging of the battery pack when managing the energy storage system, so as to prevent the problem of being unable to effectively supply power to the power user due to the failure of the charging efficiency or power supply efficiency to meet the standard during the charging and discharging process of the energy storage system;

[0074] When managing the energy storage system, when switching between charge and discharge, the ratio of the charging rate and discharge rate of the battery energy storage system to the instantaneous power consumption of all industrial and commercial units is obtained in real time, and all ratios are controlled within the charge and discharge switching range; at the same time, the instantaneous minimum discharge amount of the battery energy storage system is kept greater than or equal to the minimum discharge limit, and the minimum total discharge amount for any industrial and commercial unit is greater than or equal to the minimum discharge limit, wherein the charge and discharge switching is the switching of the battery energy storage system from the charging state to the discharging state or from the discharging state to the charging state.
