Detailed Description
The present application is described in further detail below with reference to the accompanying drawings.
The embodiment of the application provides a method for controlling the generating capacity of photovoltaic power generation, which can be executed by electronic equipment, wherein the electronic equipment can be a server or terminal equipment, and the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server for providing cloud computing service. The terminal device may be, but is not limited to, a smart phone, a tablet computer, a desktop computer, etc.
As shown in fig. 1, a method for controlling the power generation amount of photovoltaic power generation is described as follows (steps S101 to S104):
and step S1O1, obtaining the current photovoltaic power generation amount.
In this embodiment, photovoltaic power generation is one of new energy power generation, and the photovoltaic power generation field includes a photovoltaic power generation panel, an inverter, a controller, an energy storage device and the like, and after the photovoltaic power generation panel receives solar energy, electrons and ions on the photovoltaic power generation panel move by the solar energy, so that direct current is formed, and after the direct current is converted into alternating current through the inverter, the alternating current is provided for alternating current electric equipment, and after the direct current is processed, the direct current can be directly supplied for the direct current electric equipment.
After the photovoltaic power generation panel converts into direct current, the direct current is detected, and the current photovoltaic power generation amount is calculated through the direct current.
Step S102, inputting the current photovoltaic power generation amount into a corresponding preset calculation model to obtain a first power generation amount of the photovoltaic power generation field within a first preset time.
Specifically, when the preset calculation model is adopted to calculate the generated energy in the first preset time, the preset calculation model needs to be trained, and the pre-training process of the preset calculation model comprises the following steps: training data are acquired, wherein the training data comprise solar irradiation angles, illumination intensities, inclination angles of the photovoltaic panels, areas of the photovoltaic panels, temperatures of the photovoltaic panels and photoelectric conversion efficiency at corresponding moments, and the photoelectric conversion efficiency is the ratio of actual power generation power to preset power generation efficiency in unit area of the photovoltaic panels; determining a calculation function based on training data, wherein input information of the calculation function is solar irradiation angle, illumination intensity, inclination angle, area and temperature of the photovoltaic panel at different moments and photoelectric conversion efficiency at corresponding moments, and output information of the calculation function is generated energy of a photovoltaic power generation field in preset time; and establishing a preset calculation model based on the calculation function.
When training the preset calculation model, firstly, continuously repeated training is carried out by obtaining the sun illumination angle, illumination intensity, inclination angle of the photovoltaic panel, light Fu Banmian volume and photovoltaic panel temperature at different moments and the photoelectric conversion efficiency at corresponding moments, and then, a calculation function is determined according to the training data.
Because a large amount of training data is needed when training the preset calculation model, the large amount of training data can be queried from different databases or can be obtained from the existing photovoltaic power generation field, and the details are not repeated here.
It should be noted that, the solar irradiation angle is related to the geographic position of the photovoltaic power generation field, wherein the calculation formula of the solar irradiation angle is as follows:
wherein h is the sun illumination angle,
the method is characterized in that the method is used for determining the geographical latitude of a photovoltaic power generation field, sigma is solar declination, and t is local.
In this embodiment, the conversion efficiency of each photovoltaic panel is different, so the generated energy is also different, so when training data is trained, training is required to be performed one by one according to the conversion efficiency of each photovoltaic panel, and then the sum of the generated energy converted by each photovoltaic panel is calculated, so that the preset generated energy of the photovoltaic panel is obtained.
After a large amount of training data is obtained, a calculation function F (X) can be determined according to the training data, a preset calculation model is built according to the calculation function F (X), the preset calculation model is a neural network model, and simple data calculation can be completed.
Further, before the current photovoltaic power generation amount is input into the corresponding preset calculation model to obtain the first power generation amount of the photovoltaic power generation field within the first preset time, the method further comprises: acquiring historical electricity consumption and historical environment information in a preset area; establishing a model database based on the historical electricity consumption and the historical environmental information; predicting the electricity consumption of the first preset time based on the model database to obtain predicted electricity consumption; judging whether the generated energy of the photovoltaic power generation field meets the power consumption requirement or not based on the predicted power consumption; if the electricity consumption requirement is not met, the generated energy of the photovoltaic power generation field is stored before the first preset time, and the first preset time is conveniently called.
In this embodiment, after obtaining the first electricity consumption, a model database is built according to the historical electricity consumption and the historical environmental information of the preset area, that is, the electricity consumption of the first preset time is predicted through the historical electricity consumption and the historical environmental information, so as to obtain the predicted electricity consumption, whether the first electricity consumption meets the electricity consumption requirement is judged according to the predicted electricity consumption, so as to achieve the purpose of prediction.
For example, when the current time is 2023, 3, 1, and the first preset time is 2023, 3, 31, the predicted electricity consumption is 5000kwh through analysis of the model database, and the first electricity generation amount at the first preset time is 4000kwh, and the first electricity generation amount of the photovoltaic power generation field cannot meet the electricity consumption requirement, then the 1000kwh electricity can be stored in the storage device before the first preset time.
Further, storing the power generation amount of the photovoltaic power generation field before the first preset time includes: acquiring a second generating capacity in a second preset time period; judging whether the second generated energy meets the electricity consumption of a second preset time period or not; if the second generated energy meets the electricity consumption of the second preset time period, acquiring a difference value between the second generated energy and the electricity consumption of the second preset time period; determining the power generation level of the current photovoltaic power generation field based on the difference value of the second power generation amount and the power consumption amount of the second preset time period; the second power generation amount is stored based on the power generation level.
In this embodiment, when the generated energy needs to be stored before the first preset time, it is required to determine whether the difference electric quantity between the first electric quantity and the predicted generated energy can be stored in the current time and the first preset time, and in order to ensure that the power supply quantity in each preset area can meet the power consumption requirement, the first generated energy needs to be stored on a date when the first generated energy is greater than the predicted generated energy in the second preset time.
For example, the current time is 2023, 3 and 1 day, the first preset time is 2023, 3 and 31 days, and the second preset time period is 3, 1 to 31 days, wherein each day in the second preset time period meets the electricity demand, but the electricity generation amount of each day is different, some times just meet the electricity demand, and some times exceed the electricity demand, so that the electricity generation level of the photovoltaic power generation field at the corresponding time needs to be determined according to the electricity generation amount of the current day and the difference electricity quantity of the predicted electricity consumption.
That is, a plurality of difference intervals are preset, the difference electric quantity is in different difference intervals to determine different power generation levels, for example, in the embodiment, the difference intervals are divided into three difference intervals, namely, 0-250kwh, 250kwh-500kwh and more than 500kwh, all adopt left-opening and right-closing intervals, the power generation levels are divided into three, namely, a first power generation level, a second power generation level and a third power generation level, the difference interval corresponding to the first power generation level is 0-250kwh, the difference interval corresponding to the second power generation level is 250kwh-500kwh, and the difference interval corresponding to the third power generation level is more than 500 kwh.
In the present embodiment, the second power generation amount is stored only when the power generation level of the photovoltaic power generation field is at the second power generation level or the third power generation level. The second power generation amount is the difference value between the first power generation amount and the predicted power generation amount.
If the electricity demand can not be met every day in the second preset time period, the national power grid is needed to be used for supplying power to the target area.
Further, after the current photovoltaic power generation amount is input into the corresponding preset calculation model to obtain the first power generation amount of the photovoltaic power generation field within the first preset time, the method further comprises the steps of obtaining a construction plan in a preset area; judging whether the first power generation amount does not meet the requirement or not based on the construction plan; and if the generated energy does not meet the electricity demand, a power supply strategy is formulated based on the construction plan.
In this embodiment, when a construction plan exists in a preset area, if a large amount of electric energy is needed, it is determined whether the first power generation amount can meet the electricity consumption requirement, when the first power generation amount meets the electricity consumption requirement, only the photovoltaic power generation field is used for supplying power, and when the first power generation amount does not meet the electricity consumption requirement, a power supply strategy needs to be formulated according to the construction plan, so that the power supply requirement of the preset area can be ensured, and normal implementation of the construction plan can be ensured.
For example, if the storage device can store the electric quantity required by the construction plan in the second preset time, the storage device and the photovoltaic power generation field are mixed to supply power to the target area, and if the storage device cannot store the electric quantity required by the construction plan or the storage device reaches the highest storage capacity in the second preset time and cannot meet the requirement of the construction plan, the photovoltaic power generation field and the national power grid are mixed to supply power, and adjustment of the photovoltaic power generation field is not needed.
Step S103, determining the current power generation time of the photovoltaic power plant based on the first power generation amount.
Specifically, determining the current power generation time of the photovoltaic power plant based on the first power generation amount includes: establishing a digital twin power generation model based on a photovoltaic power generation field; acquiring power generation influence factors in a first preset time, wherein the power generation influence factors comprise illumination intensity, cloud layer thickness and solar irradiation angle; inputting the power generation influencing factors and the first power generation amount into a digital twin power generation model, and performing simulation operation through the digital twin power generation model to obtain an operation result; and determining the power generation time of the current photovoltaic power generation field based on the operation result.
In this embodiment, after the first power generation amount is calculated by using a preset calculation model, the power generation time of the photovoltaic power generation field needs to be determined according to the first power generation amount, where the power generation time is the power consumption time when the power generation amount of the photovoltaic power generation field meets the preset area.
And establishing a digital twin power generation model according to the photovoltaic power generation field, wherein all parameters in the digital twin power generation model correspond to each equipment parameter in the photovoltaic power generation field, so that the parameters completely conform to the parameter setting of the photovoltaic power generation field in reality, and the digital twin power generation model is used for carrying out virtual operation, so that the power generation time of the photovoltaic power generation field can be calculated.
In this embodiment, because factors influencing photovoltaic power generation exist in reality, in order to be more fit to reality, power generation influencing factors in reality need to be input into the digital twin power generation model, and data interference is performed on the digital twin power generation model as interference factors, so that an operation result of the digital twin power generation model is more fit to the reality. The power generation influencing factors are obtained through relevant approaches such as weather forecast and the like.
Further, determining the current power generation time of the photovoltaic power generation field based on the operation result includes: acquiring working equipment in a digital twin power generation model, wherein the working equipment comprises a photovoltaic power generation plate, an inverter, a storage device and a controller; determining a power loss based on the work device; determining a make-up time based on the power loss; the power generation time is adjusted based on the compensation time, so that the latest power generation time is obtained; the latest power generation time is taken as the power generation time of the current photovoltaic power plant.
In this embodiment, since there is a loss when the light energy is converted into electric energy as long as the light energy passes through the working devices, in order to more accurately generate the power time, it is necessary to calculate the electric energy loss of each working device, and compensate the electric energy loss through the storage device, so as to ensure the electricity consumption requirement in the preset area.
For example, the current power generation time is 20 hours, at this time, the calculated compensation time is 2 hours after the power consumption of the working equipment, and then the storage device of the photovoltaic power generation field is required to compensate the power generation time of 2 hours, so as to meet the power consumption requirement in the preset area, the latest power generation time is 22 hours, and the rest 2 hours provide power for the national power grid.
Step S104, power supply switching is performed based on the power generation time to ensure accurate control of the power generation amount.
In this embodiment, when the power generation time of the photovoltaic power generation field is 22 hours, for example, power is supplied from eight points in the morning, power can be continuously supplied to six points in the morning of the next day, the switch of the photovoltaic power generation field is disconnected in advance before six points in the morning of the next day, then the state power grid is connected to supply power, then the power of the power grid is cut off when the power of the photovoltaic power generation field can be supplied next time, and the power is returned to the photovoltaic power generation field to supply power, so that accurate control of the generated energy of the photovoltaic power generation field is realized, and the loss of generated energy is reduced.

and the switching module 204 is used for switching power supply based on the power generation time so as to ensure accurate control of the power generation amount.
