[0065] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0066] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0067] Figure 1 A flow chart of a distributed energy storage method for power grid optimization provided by the present invention is shown.

[0068] like Figure 1 As shown, the present invention discloses a distributed energy storage method for optimizing a power grid, comprising:

[0069] S102, storing energy in the energy storage device through the power grid, and calculating the energy storage conversion rate from the power grid to the energy storage device according to the power grid output power and the energy storage power of the energy storage device;

[0070] S104, calculating a power supply score of the energy storage device to the power consumption area based on the power supply efficiency of the energy storage device to the power consumption area and the accumulated working time of the energy storage device, and binding the energy storage device to the power consumption area with the largest power supply score;

[0071] S106, obtaining meteorological data and historical monitoring data; the historical monitoring data includes historical energy storage data and historical electricity consumption data of the power consumption area;

[0072] S108, analyzing the historical monitoring data according to the meteorological data to determine the power consumption curve of the power consumption area and the second power supply of the power grid to the power consumption area;

[0073] S110, determining a first power consumption of the power consumption area according to the second power supply power and historical power consumption data, adjusting the second power supply power based on the first power consumption of the power consumption area and the first storage capacity of the bound energy storage device, and determining a first power supply power of the power grid to the power consumption area;

[0074] S112, judging whether it is necessary to perform auxiliary energy storage for the energy storage device through the power grid according to the first power consumption of the power consumption area and the second power storage of the bound energy storage device;

[0075] S114, if yes, then analyze according to the first power supply power and power consumption curve, determine the auxiliary energy storage time interval and auxiliary energy storage power of the energy storage device bound to the power consumption area, and formulate an auxiliary energy storage task; otherwise, do nothing;

[0076] S116, performing auxiliary energy storage on the energy storage device through the power grid based on the auxiliary energy storage task.

[0077] According to an embodiment of the present invention, the power supply area of ​​the power grid is divided into multiple power consumption areas according to the power supply lines of the power grid. Each energy storage device is powered separately by the power grid in turn, and the energy storage conversion rate of the power grid to the energy storage device is determined according to the power ratio of the power grid output power and the energy storage power of the energy storage device. Each power consumption area is powered separately by the energy storage device, and the power supply efficiency of the energy storage device to each power consumption area is determined. The power supply efficiency of the energy storage device to the power consumption area and the accumulated working time of the energy storage device are multiplied by the corresponding influence weights, and the calculation results are accumulated to determine the power supply score of the energy storage device to each power consumption area. Among them, the influence weights of the power supply efficiency of the energy storage device to the power consumption area and the accumulated working time of the energy storage device are set by those skilled in the art according to actual needs. The power supply relationship between the energy storage device and the power consumption area is sorted in descending order according to the power supply score, and each energy storage device is bound to the power consumption area with the largest power supply score.

[0078] Set 24 hours as an adjustment cycle, select historical energy storage data and historical electricity consumption data of the same meteorological environment from the historical monitoring data according to the meteorological data in the current adjustment cycle for analysis, determine the power consumption curve of the power consumption area, and calculate the second power supply power of the power grid to the power consumption area when the energy storage equipment is in the auxiliary power supply state in combination with the maximum output power of the energy storage equipment bound to the power consumption area. Calculate the first storage capacity of all bound energy storage equipment during the wind and solar energy storage process through the average energy storage power curve of the energy storage equipment bound to the power consumption area during historical use, adjust the second power supply power of the power grid to the power consumption area through the first storage capacity, and determine the first power supply power of the power grid to the power consumption area.

[0079] The meteorological data predicts the second storage capacity of the energy storage equipment bound to the power consumption area through wind and solar energy storage in the current adjustment period, and the second storage capacity of all energy storage equipment is accumulated to obtain the third storage capacity, and the third storage capacity is compared with the first power consumption of the current power consumption area. When the third storage capacity is less than the first power consumption, the first power supply power and the power consumption curve are analyzed, and the first preset time interval in which the first power supply power is greater than the power consumption in the power consumption curve is determined as the energy storage time interval. The auxiliary energy storage score of each energy storage time interval is calculated, and the auxiliary energy storage time interval of each energy storage device is determined according to the auxiliary energy storage score. The auxiliary energy storage power is determined based on the power difference between the first power supply power and the power consumption curve of the current power consumption area, and the auxiliary energy storage task of each energy storage device is determined, and auxiliary energy storage is performed on the energy storage device through the power grid. For example, the energy storage device is stored by the power grid during the low electricity price period, thereby reducing the electricity cost during the peak electricity price period.

[0080] In addition, when the energy storage equipment bound to the power consumption area completes the auxiliary energy storage task, you can choose whether to continue to perform auxiliary energy storage based on actual needs (such as the electricity cost of auxiliary energy storage during the low electricity price period is lower than the electricity cost of direct power supply from the power grid during the peak electricity price period). During the auxiliary energy storage process, if the wind and solar energy storage tasks of the energy storage equipment cannot be performed, you can choose to use the storage power obtained from the auxiliary energy storage to power the power consumption area before the energy storage equipment performs wind and solar energy storage.

[0081] According to an embodiment of the present invention, it also includes:

[0082] When the number of energy storage devices bound to the power consumption area is equal to a preset number threshold, the power consumption area ends the energy storage device binding.

[0083] It should be noted that the number of energy storage devices bound to a power consumption area is determined by the system based on the historical power consumption data of the power consumption area. The higher the power consumption data, the more energy storage devices are bound to the corresponding area. When the number of energy storage devices bound to a power consumption area is equal to the preset number threshold, the power consumption area will no longer perform subsequent energy storage device allocation and binding.

[0084] Figure 2 The flowchart shows the power consumption curve of the power consumption area and the second power supply calculation method of the power grid to the power consumption area provided by the present invention.

[0085] like Figure 2 As shown, according to an embodiment of the present invention, historical monitoring data is analyzed according to meteorological data to determine a power consumption curve of a power consumption area and a second power supply of a power grid to the power consumption area, including:

[0086] S202, screening the historical monitoring data based on the meteorological data to determine the first historical energy storage data and the first historical electricity consumption data for the same meteorological environment;

[0087] S204, determining an average energy storage power curve of the energy storage device based on the first historical energy storage data;

[0088] S206, determining an electricity consumption power curve of the electricity consumption area based on the first historical electricity consumption data;

[0089] S208, accumulating the output powers of the energy storage devices bound to the power consumption area to determine a first output power;

[0090] S210, determining the maximum power consumption through the power consumption curve, and determining the second power supply power according to the difference between the maximum power consumption and the first output power; the second power supply power is the minimum power supply power of the power grid to the power consumption area when the power storage device is used to assist in power supply to the power consumption area.

[0091] It should be noted that the meteorological data is the weather forecast data (including temperature, humidity, light intensity and precipitation, etc.) within the current adjustment period. The historical energy storage data and historical electricity consumption data with the same or similar meteorological environment as the current meteorological data (i.e., environmental data similar to the current weather forecast data) are selected from the historical monitoring data, and they are respectively determined as the first historical energy storage data and the first historical electricity consumption data. The average energy storage power curve of the energy storage device is determined by calculating the average curve of the historical energy storage power curves of all the first historical energy storage data. The power consumption curve of the power consumption area is determined by calculating the average curve of the historical power consumption curves of all the first historical power consumption data. Among them, the first output power is the sum of the output powers of the energy storage devices bound to the power consumption area, that is, the maximum output power of the energy storage devices bound to the power consumption area for the power consumption area. The second power supply power is the minimum power supply power of the power grid to the power consumption area. By analyzing the power consumption curve of the power consumption area, it is ensured that the power supply of the power grid and the auxiliary power supply of the energy storage equipment meet the maximum power consumption demand of the power consumption area.

[0092] Figure 3 A flow chart showing a method for calculating a first power supply power of a power grid to a power consumption area provided by the present invention is shown;

[0093] like Figure 3 As shown, according to an embodiment of the present invention, determining the first power consumption of the power consumption area according to the second power supply power and the historical power consumption data, adjusting the second power supply power based on the first power consumption of the power consumption area and the first storage capacity of the bound energy storage device, and determining the first power supply power of the power grid to the power consumption area includes:

[0094] S302, determining the first power consumption according to the area of ​​the region formed by the second power supply power and the power consumption curve;

[0095] S304, accumulating average energy storage power curves of energy storage devices bound to the power consumption area to determine an accumulated power curve;

[0096] S306, calculating the area of ​​a region formed by the accumulated power curve and the coordinate axis to determine a first power storage capacity;

[0097] S308, compare the relationship between the first power consumption and the first power storage, when the first power consumption is greater than the first power storage, adjust the second power supply power, update the first power consumption based on the adjusted second power supply power, when the first power consumption is less than or equal to the first power storage, determine the second power supply power as the first power supply power of the power grid to the power consumption area.

[0098] It should be noted that the coordinate axis where the power consumption curve is located is a coordinate axis with an x-axis for time and a y-axis for power. The second power supply power is a rated data, which can be represented by a line segment parallel to the x-axis. The line segment represented by the second power supply power is substituted into the coordinate axis where the power consumption curve is located, and the area formed by the line segment represented by the second power supply power and the power consumption curve is calculated to determine the first power consumption of the power consumption area. Among them, in the process of calculating the first power consumption of the power consumption area, only the area formed by the line segment represented by the second power supply power below the power consumption curve is counted, and the area formed by the line segment represented by the second power supply power above the power consumption curve is not counted. The first power consumption is the electric energy data that requires energy storage equipment to provide auxiliary power supply to the power consumption area.

[0099] When the first power consumption is greater than the first storage power, it means that when the power grid supplies power to the power consumption area through the second power supply, the total storage power of the energy storage device cannot assist the power grid in supplying power to maintain the power demand of the power consumption area in the current adjustment cycle. The second power supply power of the power grid to the power consumption area is adjusted based on the first power consumption until the first storage power meets the power supply demand of the first power consumption, and the second power supply power at this time is determined as the final first power supply power of the power grid to the power consumption area.

[0100] According to an embodiment of the present invention, judging whether it is necessary to perform auxiliary energy storage on the energy storage device through the power grid according to the first power consumption of the power consumption area and the second power storage of the bound energy storage device includes:

[0101] Calculate the energy storage power curve of the energy storage device based on meteorological data;

[0102] Determine a second storage capacity of the energy storage device according to the area formed by the energy storage power curve and the coordinate axis;

[0103] Accumulate the second storage capacity of the energy storage devices bound to the power consumption area to determine the third storage capacity;

[0104] When the third power storage amount is less than the first power consumption, auxiliary energy storage is performed on the energy storage device through the power grid.

[0105] It should be noted that by analyzing the historical meteorological data combined with the historical energy storage data, the historical energy storage data that is closest to the current meteorological data is selected, and the historical energy storage power curve of the historical energy storage data is determined as the energy storage power curve of the energy storage device. When there are multiple historical energy storage data that meet the preset conditions of the system, the average curve of the historical energy storage power curves of the historical energy storage data is calculated, and the average curve is determined as the energy storage power curve of the energy storage device. The coordinate axis of the energy storage power curve is a coordinate axis with an x-axis for time and a y-axis for power.

[0106] When the third power storage capacity of all energy storage devices bound to the power consumption area is less than the first power consumption of the power consumption area, it means that the power storage capacity obtained by the energy storage devices through wind and solar energy storage during the current adjustment period cannot meet the auxiliary power supply demand of the power consumption area, and the energy storage devices need to be assisted by the power grid.

[0107] According to an embodiment of the present invention, an analysis is performed based on the first power supply power and power consumption curve to determine the auxiliary energy storage time interval and auxiliary energy storage power of the energy storage device bound to the power consumption area, and an auxiliary energy storage task is formulated, including:

[0108] Analyze the first power supply power and the power consumption curve, and determine a first preset time interval in which the first power supply power is greater than the power consumption in the power consumption curve as an energy storage time interval;

[0109] Calculate the auxiliary energy storage score of the energy storage device in each energy storage time interval according to the power difference between the first power supply power and the average power consumption in the energy storage time interval, the electricity price in the energy storage time interval, and the energy storage conversion rate of the energy storage device;

[0110] The energy storage time intervals of the energy storage devices are sorted in descending order according to the auxiliary energy storage scores;

[0111] Calculate the difference between the storage capacity of the energy storage device and the second storage capacity to determine the third storage capacity;

[0112] Determine a fourth storage capacity of the energy storage device in each energy storage time interval according to the first power supply power and power consumption curve;

[0113] According to the descending order of the auxiliary energy storage score, the fourth storage capacity of the energy storage time interval is accumulated in turn to obtain the fifth storage capacity. When the fifth storage capacity is greater than the third storage capacity, the energy storage time interval involved in the accumulation is determined as the auxiliary energy storage time interval;

[0114] The auxiliary energy storage power of the auxiliary energy storage time interval is determined according to the first power supply power and power consumption curve, and the auxiliary energy storage task of each energy storage device is determined; the auxiliary energy storage task includes the auxiliary storage amount of the energy storage device, the auxiliary energy storage power and the auxiliary energy storage time interval of the power grid.

[0115] It should be noted that the first power supply power is a rated data, which can be represented by a line segment parallel to the coordinate axis x-axis. The system divides the adjustment period into multiple first preset time intervals according to the preset time interval, and the time length of each first preset time interval is the same, which is specifically set by technicians in this field according to actual needs. By comparing the first power supply power representation line segment with the power consumption curve, one or more energy storage time intervals are determined in combination with the first preset time interval. The power difference between the first power supply power and the average power consumption in the energy storage time interval, the electricity price in the energy storage time interval, and the energy storage conversion rate of the energy storage device are multiplied by the corresponding influence weights, and the calculation results are accumulated to determine the auxiliary energy storage score of the energy storage time interval. Among them, the power difference between the first power supply power and the average power consumption in the energy storage time interval, the electricity price in the energy storage time interval, and the influence weight of the energy storage conversion rate of the energy storage device are set by technicians in this field according to actual needs. The energy storage time intervals of the energy storage device are sorted in descending order according to the auxiliary energy storage score, and the energy storage time interval with a higher auxiliary energy storage score is preferentially selected as the auxiliary energy storage time interval. The third storage capacity is the maximum remaining power amount to ensure the normal energy storage of the energy storage equipment during the wind and solar energy storage stage. The fourth storage capacity is calculated by the maximum remaining power supply power and the time length of the energy storage time interval when the power grid supplies power to the power consumption area according to the first power supply power. Among them, the auxiliary energy storage power of the auxiliary energy storage time interval is determined by the difference curve between the first power supply power representation line segment and the power consumption curve, and the auxiliary storage capacity is determined by the area formed by the auxiliary energy storage power and the coordinate axis in the auxiliary energy storage time interval. The maximum value of the auxiliary storage capacity does not exceed the third storage capacity.

[0116] According to an embodiment of the present invention, it also includes:

[0117] When the fifth power storage capacity of the power consumption area is less than the first power consumption, the power consumption area is determined as the first area, and the power difference between the first power consumption and the fifth power storage capacity is determined as the sixth power storage capacity;

[0118] Select n energy storage devices with the highest power supply scores for the first area as candidate energy storage devices;

[0119] Determine the power consumption area bound to the candidate energy storage device as the second area;

[0120] Based on the sixth storage capacity, auxiliary energy storage adjustment is performed on the energy storage device bound to the second area;

[0121] Determine the idle energy storage quota of each energy storage device according to the auxiliary energy storage task and the second energy storage capacity of each energy storage device in the second area, and allocate the auxiliary energy storage task of the candidate energy storage device to other energy storage devices;

[0122] Determine the coordinated auxiliary power supply task of the alternative energy storage device to the first area according to the idle energy storage quota adjusted by the alternative energy storage device;

[0123] Calculate a first energy storage fee based on the sixth storage capacity of the first area and the auxiliary energy storage task of the energy storage device bound to the second area;

[0124] Calculating a second energy storage fee based on the auxiliary energy storage task of the bound energy storage device after the alternative energy storage device performs auxiliary energy storage adjustment on the first area and the second area;

[0125] Calculating a cost ratio of the second energy storage cost to the first energy storage cost;

[0126] The second areas are sorted in ascending order according to the cost ratio, and the storage capacity of the alternative energy storage devices in each second area is accumulated in turn to determine the seventh storage capacity. When the seventh storage capacity is greater than the sixth storage capacity, the alternative energy storage devices participating in the accumulation are determined as collaborative energy storage devices, and collaborative energy storage is performed on the collaborative energy storage devices according to the collaborative auxiliary power supply task.

[0127] It should be noted that when the actual storage capacity of the energy storage device bound to the power consumption area cannot meet the power demand of the power consumption area in the current adjustment cycle through wind and solar energy storage and grid auxiliary energy storage, the energy storage devices bound to other power consumption areas are used for collaborative energy storage, and the current power consumption area is determined as the first area. According to the power supply scores of the energy storage devices bound to other power consumption areas and the first area, n energy storage devices with the highest energy storage scores are selected as alternative energy storage devices. The value of n is set and adjusted by technical personnel in this field according to actual needs, and the application area of ​​the alternative energy storage device is determined as the second area. Among them, the sixth storage capacity is the storage capacity that requires other energy storage devices for collaborative energy storage. Based on the sixth storage capacity, the auxiliary energy storage of the energy storage device bound to the second area is adjusted, and the auxiliary energy storage task of the alternative energy storage device is assigned to other energy storage devices, and the maximum idle energy storage quota of the alternative energy storage device without affecting the wind and solar energy storage is determined. In the allocation process, other energy storage devices with higher power supply scores are given priority for allocation. The additional power supply cost of adjusting the first power supply power of the power grid to the power consumption area during the peak power consumption period is calculated according to the sixth storage capacity and the electricity price during the peak power consumption period. The auxiliary energy storage cost of the power grid to the energy storage device bound to the second area is calculated according to the auxiliary energy storage task of the energy storage device bound to the second area, which is expressed as the first auxiliary energy storage cost. The additional power supply cost of the first power supply power and the first auxiliary energy storage cost of the second area are added to determine the first energy storage cost. The coordinated auxiliary power supply cost of the alternative energy storage device is calculated through the coordinated auxiliary power supply task of the alternative energy storage device to the first area. The auxiliary energy storage cost of the power grid to the energy storage device bound to the second area is calculated according to the auxiliary energy storage task of the bound energy storage device after the auxiliary energy storage adjustment in the second area, which is expressed as the second auxiliary energy storage cost. The coordinated auxiliary power supply cost of the alternative energy storage device and the second auxiliary energy storage cost of the second area are added to determine the second energy storage cost. The cost ratio of the second energy storage cost to the first energy storage cost is calculated. The lower the cost ratio, the lower the cost of the coordinated auxiliary energy storage. The storage capacity of each candidate energy storage device is accumulated in turn according to the cost ratio to determine the cooperative energy storage device for cooperative auxiliary energy storage in the first area. The auxiliary energy storage tasks of other energy storage devices in the second area corresponding to the cooperative energy storage device are adjusted according to the auxiliary energy storage adjustment.

[0128] According to an embodiment of the present invention, it also includes:

[0129] Calculate the allocation score according to the total coordinated dispatch times and total dispatched power of the power consumption area on the power supply line of the power grid within the second preset time interval;

[0130] When the allocation score is greater than a preset score threshold, the first power supply power is reallocated to each power consumption area.

[0131] It should be noted that the total number of coordinated dispatches for all power consumption areas on the power grid power supply line and the dispatched electricity generated in each coordinated dispatch process are counted, and the dispatched electricity is accumulated to determine the total dispatched electricity. The total number of coordinated dispatches and the total dispatched electricity are multiplied by the corresponding influence weights, and the calculation results are accumulated to determine the allocation score of the second preset time interval. Among them, the influence weights of the total number of coordinated dispatches and the total dispatched electricity are set by technicians in this field according to actual needs.

[0132] The allocation score is compared with the preset score threshold. When the allocation score is less than or equal to the preset score threshold, no processing is performed; when the allocation score is greater than the preset score threshold, the first power supply power of the power grid to each power consumption area is recalculated. The second preset time interval and the preset score threshold are set by those skilled in the art according to actual needs.
