Example one
Fig. 1 is a flowchart of an embodiment of the present invention, which provides a light-storage cooperative configuration method applied to a light-storage straight and flexible building, where this embodiment is applicable to a situation of configuring a photovoltaic system of a light-storage straight and flexible building, and the method may be executed by a light-storage cooperative configuration apparatus applied to a light-storage straight and flexible building, where the apparatus may be implemented in a form of hardware and/or software. As shown in fig. 1, the method includes:
and step S110, acquiring a photovoltaic output curve of the light storage straight and flexible building.
Optionally, obtain the photovoltaic output curve of the gentle building of light storage directly, include: determining the installation capacity of the light storage straight flexible building; and acquiring a photovoltaic output curve according to the installation capacity and the solar irradiance value.
Optionally, determining the installation capacity of the light storage straight and flexible building includes: obtaining the effective available area, unit photovoltaic occupied area and unit photovoltaic capacity of the light storage straight flexible building; determining the number of unit photovoltaic cells according to the effective available area and the unit photovoltaic occupation area; and determining the installation capacity of the light storage straight flexible building according to the number of the unit photovoltaic and the unit photovoltaic capacity.
Specifically, in the embodiment, the photovoltaic modules can be installed on the building roof and the building outer vertical surface of the light-storing straight and flexible building, so that the effective available area S1 of the building roof and the effective available area S2 of the building outer vertical surface are obtained, and the effective available area in the embodiment refers to the building area which has the condition for installing the photovoltaic modules and can receive the sunlight irradiation by the installed photovoltaic modules. In this embodiment, parameters of the photovoltaic module are obtained, and the parameters of the photovoltaic module may specifically be a unit photovoltaic occupied area and a unit photovoltaic capacity. Because the building roof is not blocked by a barrier, the irradiation time of sunlight is relatively long, and in order to ensure that the light storage straight and flexible building can output as much electric quantity as possible, the types of the photovoltaic modules adopted by 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 Cpv 1; the unit photovoltaic occupied area installed on the building facade is Spv2, and the unit photovoltaic capacity is Cpv 2.
It should be noted that, because preset conditions are preset for both the building roof area and the building facade area, the constraint condition for the building roof area is Npv1 × Spv1 ≤ S1, and the number of unit photovoltaic cells used in the building roof can be determined to be Npv1 according to the maximum utilization rate; the constraint condition for the area of the building facade is Npv2 × Spv2 ≦ S2, the number of unit photovoltaics used by the building facade may be determined to Npv2 according to the maximum utilization rate, and thus, according to the number of unit photovoltaics used in the building roof and the building facade and the unit photovoltaic capacity, the installation capacity of the photovoltaic in the light storage straight and flexible building may be determined to be Ps Npv1 × Cpv1+ Npv2 × Cpv 2.
After the installation capacity Ps of the light storage and light storage straight and flexible building is determined, a photovoltaic output curve can be obtained according to the installation capacity and the solar irradiance value, the photovoltaic output curve is used for representing the electric quantity output condition of the light storage and light storage straight and flexible building along with the change of time, and the photovoltaic output curve can be specifically represented by adopting the following formula (1):

wherein, Ppv(t) represents the actual output of the photovoltaic cell in kW; ps represents the installation capacity of the photovoltaic cell, and is also the rated power of the photovoltaic cell, and the unit is kW; gr (t) represents the actual irradiation intensity of the photovoltaic cell at the location, in W/m2(ii) a Gs represents the standard solar irradiance of 1000W/m2(ii) a k is the temperature coefficient of the photovoltaic cell; tr represents the actual temperature of the location of the photovoltaic cell, in units; ts represents the actual temperature of the photovoltaic cell surface under standard conditions.

Therefore, the two configuration targets are completely different, and the photovoltaic configuration modes adopted by the different configuration targets are different.
And step S130, selecting a load curve according to the energy storage configuration target.
Optionally, selecting a load curve according to the energy storage configuration target includes: when the energy storage configuration target is that the photovoltaic is consumed to the maximum extent, the load curve is a first load curve, wherein the first load curve is collected by the light storage straight flexible building on a typical day when the daily consumed electric quantity is smaller than a preset threshold value; and when the energy storage configuration target is peak-valley arbitrage, the load curve is a second load curve, wherein the second load curve is collected by the light storage straight flexible building on a typical day with the daily consumed electric quantity larger than a preset threshold value.
The load curve is used for representing the electricity consumption condition of the light storage straight and flexible building along with the change of time. When the energy storage configuration target is photovoltaic consumption to the maximum extent, extracting a typical day with relatively less power consumption, such as a first load curve of a winter non-working day, from collected annual load power utilization curves of a building access current distribution part; when the energy storage configuration target is peak-valley arbitrage, a typical day with relatively high power consumption, such as a second load curve of a summer working day, is extracted from the collected annual load power utilization curve of the building access current power distribution part.
And step S140, configuring the energy storage capacity and the energy storage charging and discharging power of the photovoltaic in the light storage straight and soft building according to the photovoltaic output curve and the load curve.
Optionally, the configuring the energy storage capacity and the energy storage charging and discharging power of the photovoltaic in the light storage straight and soft building according to the photovoltaic output curve and the load curve includes: determining a load curve as a first load curve matched with the maximum consumption photovoltaic; and configuring the energy storage capacity and the energy storage charging and discharging power of the photovoltaic in the light storage straight and soft building according to the photovoltaic output curve and the first load curve.
Optionally, according to the photovoltaic output curve and the load curve, the energy storage capacity and the energy storage charge and discharge power of the photovoltaic in the light storage straight-flexible building are configured, including: determining the load curve as a second load curve matched with the peak valley arbitrage; and configuring the energy storage capacity and the energy storage charging and discharging power of the photovoltaic in the light storage straight and soft building according to the photovoltaic output curve and the second load curve.
When the photovoltaic output curve is determined and the load curve collected according to the actual configuration target is determined, the reasonable configuration of the energy storage capacity and the energy storage charging and discharging power of the photovoltaic in the light storage straight and soft building is realized according to the photovoltaic output curve and different load curves.
In the embodiment of the application, photovoltaic output curve through store up the straight gentle building of light to and according to the load curve that the energy storage configuration target actually obtained, dispose the photovoltaic, thereby combined the actual power generation situation and the power consumption demand of the straight gentle building of light storage, avoided energy storage capacity's waste when carrying out the photovoltaic configuration, improved the economy of the straight gentle building of light storage, realized renewable resources's rational utilization.

The second scenario is that the peak value of the photovoltaic output curve is smaller than the second load curve, and the judgment basis is the following formula (5)
Figure BDA0003634554800000092
Fig. 7 is a graph comparing the curves in the second scenario.
And step S320, configuring the energy storage capacity and the energy storage charging and discharging power of the photovoltaic in the light storage straight and soft building according to the photovoltaic output curve and the second load curve.
Optionally, the energy storage capacity and the energy storage charge and discharge power of the photovoltaic in the light storage straight-flexible building are configured according to the photovoltaic output curve and the second load curve, and the method includes: when the peak value of the photovoltaic output curve is larger than the second load curve, determining a first consumed electric quantity of the light storage straight flexible building within a first specified time range under the condition of no illumination and a first power value corresponding to the peak value of the second load curve within the first specified time range; the first consumed electric quantity is used as the energy storage capacity of the photovoltaic, and the first power value is used as the energy storage charging and discharging power of the photovoltaic; wherein the first specified time range matches the peak period of the electricity prices in the absence of illumination.
Specifically, in the first scenario, as shown in fig. 6, the light-storing straight and flexible building has more photovoltaic, and in this scenario, the stored energy can be used to charge at the valley period of night and discharge at the peak period of night, that is, charge and discharge are performed at once. At this time, the first consumed electric quantity of the light storage straight flexible building in the first specified time range is determined, and since the first specified time range is matched with the peak period of the electricity price under the condition of no illumination, the first specified time range can be specifically 17 to 19 points, and the photovoltaic output curve is basically close to zero at this time, the first consumed electric quantity can be obtained in the area formed by the second load curve and the horizontal axis. In addition, the first power value corresponding to the peak value of the second load curve in the range from 17 to 19 points is 150kw, so that 150kw is used as the energy storage charging and discharging power of the photovoltaic cell.
