[0035] Embodiment 1

[0036] Figure 1 FIG. is a flowchart of a photovoltaic and energy storage collaborative configuration method applied to a photovoltaic and energy storage direct-current flexible building according to Embodiment 1 of the present invention. This embodiment is applicable to the case of configuring the photovoltaic of a photovoltaic and energy storage direct-current flexible building. This method can be executed by a photovoltaic and energy storage collaborative configuration device applied to a photovoltaic and energy storage direct-current flexible building, and this device can be implemented in the form of hardware and / or software. As Figure 1 shown, this method includes:

[0037] Step S110, obtaining the photovoltaic output curve of the photovoltaic and energy storage direct-current flexible building.

[0038] Optionally, obtaining the photovoltaic output curve of the photovoltaic and energy storage direct-current flexible building includes: determining the installation capacity of the photovoltaic and energy storage direct-current flexible building; obtaining the photovoltaic output curve according to the installation capacity and the solar irradiance value.

[0039] Optionally, determining the installation capacity of the photovoltaic and energy storage direct-current flexible building includes: obtaining the effective available area, the unit photovoltaic occupied area and the unit photovoltaic capacity of the photovoltaic and energy storage direct-current flexible building; determining the number of unit photovoltaics according to the effective available area and the unit photovoltaic occupied area; determining the installation capacity of the photovoltaic and energy storage direct-current flexible building according to the number of unit photovoltaics and the unit photovoltaic capacity.

[0040] Specifically, in this embodiment, photovoltaic modules can be installed on both the building roof and the building facade of the photovoltaic-storage-direct-current-flexible building. Therefore, the effective available area S1 of the building roof and the effective available area S2 of the building facade will be obtained. The effective available area in this embodiment refers to the building area that meets the conditions for installing photovoltaic modules and where the installed photovoltaic modules can receive sunlight. In this embodiment, the parameters of the photovoltaic modules will be obtained. The parameters of the photovoltaic modules can specifically be the unit photovoltaic occupied area and the unit photovoltaic capacity. Since the building roof is not blocked by obstacles, the sunlight irradiation duration is relatively long. To ensure that the photovoltaic-storage-direct-current-flexible building can output as much electricity as possible, the types of photovoltaic modules used on the building roof and the building facade can be different. For example, the unit photovoltaic occupied area installed on the building roof is Spv1, and the unit photovoltaic capacity is Cpv1; the unit photovoltaic occupied area installed on the building facade is Spv2, and the unit photovoltaic capacity is Cpv2.

[0041] It should be noted that since preset conditions are set for both the building roof area and the building facade area in advance, the constraint condition for the building roof area is Npv1 * Spv1 ≤ S1. According to the maximum utilization rate, the number of unit photovoltaics used in the building roof can be determined as Npv1; the constraint condition for the building facade area is Npv2 * Spv2 ≤ S2. According to the maximum utilization rate, the number of unit photovoltaics used in the building facade can be determined as Npv2. Thus, according to the number of unit photovoltaics and the unit photovoltaic capacity used in the building roof and the building facade, the installation capacity of the photovoltaic in the photovoltaic-storage-direct-current-flexible building can be determined as Ps = Npv1 * Cpv1 + Npv2 * Cpv2. Of course, in this embodiment, only an example is given, and the symbols used for each parameter are not specifically limited.

[0042] Among them, after determining the installation capacity Ps of the photovoltaic-storage-direct-current-flexible building, the photovoltaic output curve can be obtained according to the installation capacity and the solar irradiance value. The photovoltaic output curve is used to represent the power output status of the photovoltaic-storage-direct-current-flexible building changing with time. Specifically, the photovoltaic output curve can be represented by the following formula (1):

[0043]

[0044] Among them, P pv (t) represents the actual output of the photovoltaic cell, with the unit of kW; Ps represents the installation capacity of the photovoltaic, and at the same time, it is also the rated power of the photovoltaic cell, with the unit of kW; Gr(t) represents the actual irradiation intensity at the location of the photovoltaic cell, with the unit of W / m 2 ; Gs represents the standard solar irradiance of 1000 W / m 2; k is the temperature coefficient of the photovoltaic cell; Tr represents the actual temperature at the location of the photovoltaic cell, in °C; Ts represents the actual temperature on the surface of the photovoltaic cell under standard conditions.

[0045] Step S120, determine the energy storage configuration target specified by the user.

[0046] Specifically, in this embodiment, the terminal device will also receive a configuration instruction from the user. The configuration instruction contains the energy storage configuration target specified by the user. The energy storage configuration target includes maximizing the consumption of photovoltaic power or peak-valley arbitrage. Maximizing the consumption of photovoltaic power can maximize the storage of the electricity output by the photovoltaic-storage-direct-current-soft building. Peak-valley arbitrage can maximize the savings on electricity bills, enabling the user to obtain the maximum benefit. Therefore, the two configuration targets are completely different, and the photovoltaic configuration methods adopted for different configuration targets also have differences.

[0047] Step S130, select a load curve according to the energy storage configuration target.

[0048] Optionally, selecting a load curve according to the energy storage configuration target includes: when the energy storage configuration target is to maximize the consumption of photovoltaic power, the load curve is the first load curve, where the first load curve is collected on a typical day when the daily power consumption of the photovoltaic-storage-direct-current-soft building is less than a preset threshold; when the energy storage configuration target is peak-valley arbitrage, the load curve is the second load curve, where the second load curve is collected on a typical day when the daily power consumption of the photovoltaic-storage-direct-current-soft building is greater than a preset threshold.

[0049] Among them, the load curve is used to represent the power consumption status of the photovoltaic-storage-direct-current-soft building changing with time. And the load curves selected according to different energy storage configuration targets also have differences. When the energy storage configuration target is to maximize the consumption of photovoltaic power, then from the annual load power consumption curves of the building access current distribution part collected, a typical day with relatively less power consumption is extracted, such as the first load curve on a non-working day in winter; when the energy storage configuration target is peak-valley arbitrage, then from the annual load power consumption curves of the building access current distribution part collected, a typical day with relatively more power consumption is extracted, such as the second load curve on a working day in summer.

[0050] Step S140, configure the energy storage capacity and energy storage charge-discharge power of the photovoltaic in the photovoltaic-storage-direct-current-soft building according to the photovoltaic output curve and the load curve.

[0051] Optionally, configuring the energy storage capacity and energy storage charge-discharge power of the photovoltaic in the photovoltaic-storage-direct-current-soft building according to the photovoltaic output curve and the load curve includes: determining that the load curve is the first load curve matching the maximum consumption of photovoltaic power; configuring the energy storage capacity and energy storage charge-discharge power of the photovoltaic in the photovoltaic-storage-direct-current-soft building according to the photovoltaic output curve and the first load curve.

[0052] Optionally, according to the photovoltaic output curve and the load curve, configure the energy storage capacity and the energy storage charge-discharge power of the photovoltaic in the building with direct current injection from photovoltaic and energy storage, including: determining that the load curve is the second load curve matching peak-valley arbitrage; configuring the energy storage capacity and the energy storage charge-discharge power of the photovoltaic in the building with direct current injection from photovoltaic and energy storage according to the photovoltaic output curve and the second load curve.

[0053] When the photovoltaic output curve is determined and the load curve collected according to the actual configuration target, according to the photovoltaic output curve and different load curves, a reasonable configuration of the energy storage capacity and the energy storage charge-discharge power of the photovoltaic in the building with direct current injection from photovoltaic and energy storage is achieved.

[0054] In the embodiment of the present application, by using the photovoltaic output curve of the building with direct current injection from photovoltaic and energy storage and the load curve actually obtained according to the energy storage configuration target, the photovoltaic is configured, so that the actual power generation situation and the electricity consumption demand of the building with direct current injection from photovoltaic and energy storage are combined, the waste of energy storage capacity is avoided during photovoltaic configuration, the economy of the building with direct current injection from photovoltaic and energy storage is improved, and the reasonable utilization of renewable resources is realized.

[0055] Embodiment 2

[0056] Figure 2 The flowchart of a photovoltaic and energy storage collaborative configuration method applied to a building with direct current injection from photovoltaic and energy storage provided in Embodiment 2 of the present invention is shown. In this embodiment, when it is determined that the energy storage configuration target is to maximize the consumption of photovoltaic power, step S140 is specifically described. As Figure 2 shown, the method includes:

[0057] Step S210, determining that the load curve is the first load curve matching the maximum consumption of photovoltaic power.

[0058] Specifically, when it is determined that the energy storage configuration target is to maximize the consumption of photovoltaic power, then it is determined that the load curve is the first load curve on a non-working day in winter, and the first load curve on a non-working day in winter can be represented by P load，winter (t), and there are two scenarios for the configuration target of maximizing the consumption of photovoltaic power:

[0059] The first scenario is that the peak value of the photovoltaic output curve is greater than the first load curve, and the determination basis is the following formula (2)

[0060]

[0061] Among them, P pv,winter (t) is the photovoltaic output on a non-working day in winter; P load,winter (t) is the load on a non-working day in winter, and as Figure 3 shown is the curve comparison schematic diagram in the first scenario.

[0062] The second scenario is that the peak value of the photovoltaic output curve is less than the first load curve, and the judgment basis is the following formula (2).

[0063]

[0064] As Figure 4 shown, it is a schematic diagram of curve comparison in the second scenario.

[0065] Step S220: Configure the energy storage capacity and energy storage charge and discharge power of the photovoltaic in the photovoltaic-storage-direct-flexible building according to the photovoltaic output curve and the first load curve.

[0066] Optionally, configuring the energy storage capacity and energy storage charge and discharge power of the photovoltaic in the photovoltaic-storage-direct-flexible building according to the photovoltaic output curve and the first load curve includes: when the peak value of the photovoltaic output curve is greater than the first load curve, determining the remaining power value of the output power of the photovoltaic-storage-direct-flexible building being greater than the consumed power, and the photovoltaic output value matching the peak value of the photovoltaic output curve; using the remaining power value as the energy storage capacity of the photovoltaic, and using the matching photovoltaic output value as the energy storage charge and discharge power of the photovoltaic.

[0067] Specifically, when it is the above-mentioned first scenario, as Figure 3 shown, between 7 o'clock and 16 o'clock, the area formed by the photovoltaic output curve and the first load curve is the remaining power value obtained after the output power is used, and the photovoltaic output value matching the peak value of the photovoltaic output curve is 100 kw. Therefore, the remaining power is used as the energy storage capacity of the photovoltaic, and 100 kw is used as the energy storage charge and discharge power of the photovoltaic.

[0068] Optionally, configuring the energy storage capacity and energy storage charge and discharge power of the photovoltaic in the photovoltaic-storage-direct-flexible building according to the photovoltaic output curve and the load curve includes: when the peak value of the photovoltaic output curve is less than the first load curve, configuring the energy storage capacity of the photovoltaic and the energy storage charge and discharge power of the photovoltaic to zero.

[0069] Among them, when it is the above-mentioned second scenario, as Figure 4 shown, the power output by the photovoltaic can be completely consumed by the winter non-working day load. At this time, the configuration of energy storage for photovoltaic consumption is not considered, that is, the energy storage capacity of the photovoltaic and the energy storage charge and discharge power of the photovoltaic can be configured to zero.

[0070] Embodiment 3

[0071] Figure 5 The following is a flowchart of a photovoltaic-storage collaborative configuration method applied to a photovoltaic-storage-direct-flexible building provided in Embodiment 3 of the present invention. In this embodiment, when it is determined that the energy storage configuration target is peak-valley arbitrage, step S140 is specifically described. As Figure 5 shown, the method includes:

[0072] Step S310: Determine that the load curve is the second load curve matching peak-valley arbitrage.

[0073] Specifically, when the energy storage configuration target is determined to be peak-valley arbitrage, the load curve is determined to be the second load curve on a summer weekday, and the second load curve on a summer weekday can be represented by P oad，summer (t), and there are two scenarios for the configuration target of peak-valley arbitrage:

[0074] The first scenario is that the peak value of the photovoltaic output curve is greater than the second load curve, and the determination basis is the following formula (4)

[0075]

[0076] where P pv,summer (t) is the photovoltaic output on a summer weekday; P load,summer (t) is the load on a summer weekday, and as Figure 6 shown is the curve comparison schematic diagram in the first scenario.

[0077] The second scenario is that the peak value of the photovoltaic output curve is less than the second load curve, and the determination basis is the following formula (5)

[0078]

[0079] As Figure 7 shown, it is the curve comparison schematic diagram in the second scenario.

[0080] Step S320: Configure the energy storage capacity and energy storage charge-discharge power of the photovoltaic in the photovoltaic-storage-direct-current building according to the photovoltaic output curve and the second load curve.

[0081] Optionally, configuring the energy storage capacity and energy storage charge-discharge power of the photovoltaic in the photovoltaic-storage-direct-current building according to the photovoltaic output curve and the second load curve includes: when the peak value of the photovoltaic output curve is greater than the second load curve, determining the first power consumption of the photovoltaic-storage-direct-current building within the first specified time range in the case of no sunlight, and the first power value corresponding to the peak value of the second load curve within the first specified time range; taking the first power consumption as the energy storage capacity of the photovoltaic, and taking the first power value as the energy storage charge-discharge power of the photovoltaic; where the first specified time range matches the peak period of the electricity price in the case of no sunlight.

[0082] Specifically, when it is the first scenario as described above, as Figure 6As shown, there is a relatively large amount of photovoltaics in the building with integrated photovoltaics, energy storage, DC power supply, and flexible AC power transmission. In this scenario, energy storage can be used to charge during the night valley period and discharge during the evening peak period, that is, one charge and one discharge. At this time, the first power consumption of the building with integrated photovoltaics, energy storage, DC power supply, and flexible AC power transmission within the first specified time range is determined. Since the first specified time range matches the electricity price peak period under no sunlight conditions, the first specified time range can specifically be from 17:00 to 19:00. At this time, the photovoltaic output curve is basically close to zero. Therefore, the area formed by the second load curve and the horizontal axis can be taken as the first power consumption. In addition, the first power value corresponding to the peak value of the second load curve within the range of 17:00 to 19:00 is 150 kw. Thus, 150 kw is taken as the energy storage charge-discharge power of the photovoltaics.

[0083] Optionally, according to the photovoltaic output curve and the second load curve, configure the energy storage capacity and the energy storage charge-discharge power of the photovoltaics in the building with integrated photovoltaics, energy storage, DC power supply, and flexible AC power transmission, including: when the peak value of the photovoltaic output curve is less than the second load curve, determine the first power consumption of the building with integrated photovoltaics, energy storage, DC power supply, and flexible AC power transmission within the first specified time range under no sunlight conditions, and the first power value corresponding to the second load curve within the first specified time range; determine the second power consumption when the power consumption of the building with integrated photovoltaics, energy storage, DC power supply, and flexible AC power transmission within the second specified time range under sunlight conditions is greater than the output power, and the second power value corresponding to the peak value difference between the photovoltaic curve and the second load curve, where the second specified time range matches the electricity price peak period under sunlight conditions; configure the energy storage capacity and the energy storage charge-discharge power of the photovoltaics in the building with integrated photovoltaics, energy storage, DC power supply, and flexible AC power transmission according to the first power consumption, the second power consumption, the first power value, and the second power value.

[0084] Optionally, configure the energy storage capacity and the energy storage charge-discharge power of the photovoltaics in the building with integrated photovoltaics, energy storage, DC power supply, and flexible AC power transmission according to the first power consumption, the second power consumption, the first power value, and the second power value, including: determine the power consumption with the larger value between the first power consumption and the second power consumption, and take the power consumption with the larger value as the energy storage capacity of the photovoltaics; determine the power value with the larger value between the first power value and the second power value, and take the power value with the larger value as the energy storage charge-discharge power of the photovoltaics.

[0085] Specifically, when it is the above-mentioned second scenario, as Figure 7 shown, in this scenario, energy storage can be fully utilized to charge during the night valley period, discharge during the daytime peak period, charge during the noon flat period, and discharge during the evening peak period, that is, two charges and two discharges. At this time, the first power consumption of the building with integrated photovoltaics, energy storage, DC power supply, and flexible AC power transmission within the first specified time range is determined. The first specified time range matches the electricity price peak period under no sunlight conditions. Therefore, the first specified time range can specifically be from 17:00 to 19:00. Since the photovoltaic output curve is basically close to zero at this time, the area formed by the second load curve and the horizontal axis can be taken as the first power consumption of 300 kw. The first power value corresponding to the peak value of the second load curve within the range of 17:00 to 19:00 is 150 kw.

[0086] Similarly, the second power consumption in which the power consumption of the photovoltaic-storage-direct-current-soft building is greater than the power output within the second specified time range will also be determined. The second specified time range matches the peak electricity price under sunlight. For example, the second specified time range can specifically be from 10:00 to 12:00. Since the photovoltaic output curve is not zero at this time, the area formed by the second load curve and the photovoltaic curve is taken as the second power consumption of 200 kw. The second power value corresponding to the peaks of the photovoltaic output curve and the second load curve within the range from 10:00 to 12:00 is 200 kw - 100 kw = 100 kw. Since the first power consumption is greater than the second power consumption, it is determined that 300 kw is used as the energy storage capacity of the photovoltaic; since the first power value is greater than the second power value, 100 kw is used as the energy storage charge-discharge power of the photovoltaic. Of course, in this embodiment, only examples are given, and the specific values of the energy storage capacity and the energy storage charge-discharge power of the photovoltaic are not limited.
