As shown in fig. 2, the process 200 includes the steps of:
step 210, determining a power generation characteristic of the photovoltaic device based on the first monitoring data.

The cleaning degree of the photovoltaic equipment can be influenced by weather data, and the cleaning degree of the photovoltaic equipment is good after raining.

In some embodiments, the power generation characteristic may include a sequence of power generation for a preset period of time. The power generation sequence may include at least one time in the future and the power generation or power generation of the corresponding predicted photovoltaic device.
In some embodiments, the processor may determine the power generation characteristics in a variety of ways. Such as lookup tables, vector library matches, etc. For example only, the processor may query a preset, previously established power generation table for power generation characteristics of the photovoltaic device corresponding thereto based on the first monitoring data.
In some embodiments, the processor may also determine the power generation characteristics through a power generation predictive model, see FIG. 3 and its associated description for further details.
Step 220, determining the electricity utilization characteristic of the electric equipment connected to the photovoltaic equipment based on the second monitoring data.
The second monitoring data may reflect a historical power usage status of the powered device. In some embodiments, the second monitoring data may include at least one of a historical power usage characteristic and a current power usage characteristic of the powered device. The historical electricity utilization characteristic and the current electricity utilization characteristic can comprise electricity utilization sequences of the electric equipment in preset time. The electricity consumption sequence may include electricity consumption or electricity consumption power (i.e., electricity consumption power) of the photovoltaic device and an electricity consumption time corresponding thereto.
In some embodiments, the processor may obtain the second monitoring data through the monitoring component. For example, the processor may obtain historical electricity usage of the consumer over a plurality of time periods via the electricity meter to determine historical electricity usage characteristics of the consumer.
The electricity utilization characteristics of the electric equipment connected with the photovoltaic equipment can reflect the electricity utilization state of the electric equipment in a certain time period. In some embodiments, the power usage characteristics may include a predicted power usage sequence of the powered device over a current time period or a future preset time period. The electricity consumption sequence may include predicted electricity consumption or electricity consumption power of the electric equipment and the corresponding electricity consumption time. For more details on powered devices, reference may be made to fig. 1 and the associated description.
In some embodiments, the processor may determine the power usage characteristics in a variety of ways. Such as lookup tables, vector library matches, etc. For example only, the processor may match similar vectors in a preset electric device vector library established in advance based on the vectors corresponding to the second monitoring data, thereby determining electric characteristics corresponding to the similar vectors, and using the electric characteristics as electric devices connected to the photovoltaic device.
In some embodiments, the processor may determine the power usage characteristics by a power usage prediction model, see FIG. 4 and its associated description for further details.
Step 230, determining a power supply strategy of the photovoltaic device based on the power generation characteristic and the power usage characteristic.
The power supply strategy may be a strategy that directs the distribution of electrical energy over a certain period of time in the future. In some embodiments, the power supply strategy may include power distribution characteristics of the photovoltaic device during the energy-surplus phase, such as the power supplied to the powered device, and the stored power stored to the energy storage assembly; and the electricity buying characteristics of the photovoltaic equipment in the energy deficiency stage, such as whether electricity buying is needed or not, and electricity buying power, wherein the electricity buying power refers to the electric quantity required to be bought from a power grid in unit time. The energy-surplus phase can be a phase that the generated energy of the photovoltaic equipment is larger than the power consumption of the electric equipment, and otherwise, the energy-shortage phase is the energy-shortage phase.
Correspondingly, in some embodiments, the photovoltaic device is in an energy-surplus phase, and the energy storage component can be charged; and if the energy storage component is full in electric quantity, redundant power generation electric energy of the photovoltaic equipment can be input to a power grid to obtain income. In some embodiments, the photovoltaic device is in the energy-deficient stage, and the electric device can be powered by the electric quantity stored by the energy storage component; if the energy storage component is exhausted, electric energy can be purchased from the power grid to meet the requirement that the electric equipment can consume electricity at the moment, and expenditure is generated. For more details of the energy storage assembly, reference may be made to fig. 1 and the associated description.
In some embodiments, the processor may determine the target power supply policy in a variety of ways. For example by consulting a reference power policy table. Wherein the reference power policy table may be pre-established by the processor based on historical power data. The reference power supply strategy table comprises scene characteristics and corresponding reference power supply strategies. Wherein, scene characteristics may include: the power generation characteristics of the photovoltaic equipment at the current moment or the future moment, the power utilization characteristics of the electric equipment and the electricity price. The processor may determine the target power supply policy based on matching scene features in the reference power supply policy table.
In some embodiments, the processor may obtain at least one candidate power supply strategy, determine an evaluation value of the at least one candidate power supply strategy based on the power usage characteristics and the power generation characteristics, and determine a target power supply strategy from the at least one candidate power supply strategy based on the evaluation value.
In some embodiments, the processor may generate the at least one candidate power supply policy in a variety of ways. For example, randomly generated based on scene features, or generated based on historical data, etc.
In some embodiments, the evaluation value of the candidate power supply strategy may be affected by the purchase cost and the amount of power supplied after the power supply strategy is implemented. For example, the lower the purchase cost after the power supply strategy is implemented, the higher the evaluation value, and for example, the larger the power supply amount after the power supply strategy is implemented, the higher the evaluation value.
In some alternative embodiments, the processor may determine the evaluation value based on a purchase cost, which may be inversely proportional to the evaluation value. In some alternative embodiments, the processor may take as an evaluation a ratio of the amount of power supplied and the cost of purchasing power. In some alternative embodiments, the processor may weight the purchase cost and the power supply amount to obtain the evaluation value of the candidate power supply policy, where the power supply amount weight is positive, the purchase cost weight is negative, and the specific value of the weight may be preset or determined by acquiring a manual input.
In some embodiments, the processor may determine the evaluation value of each candidate power supply strategy by simulating the purchase cost and the amount of power supplied by executing the candidate power supply strategy for a preset period of time (e.g., within 24 hours in the future) based on the candidate power supply strategy. The preset time period may be set manually.
For example, at each time during the simulation, the processor may determine the power supplied and stored, and whether to purchase and purchase power, and continue the simulation based on the power characteristics, power generation characteristics, and candidate power supply strategies at that time or at a future time. When the simulation is completed, the processor can count the buying power in the simulation process based on the monitoring data in the simulation process, and then determine the buying cost based on the electricity price; and determining the power supply quantity of the electric equipment based on the monitoring data in the simulation process, and determining the evaluation value of the candidate power supply strategy based on the electricity buying cost and the power supply quantity.
The processor can simulate generation of a photovoltaic device in the simulation system, and different generation powers are given to the photovoltaic device at different moments according to the predicted generation characteristics, so that the generation characteristics of the photovoltaic device at future moments are simulated. The processor can also generate a charging event in the simulation system (for example, simulate an electric vehicle to charge), and ensure that the generation of the charging event is matched with the predicted electricity utilization characteristic, so as to simulate the electricity utilization characteristic of the electric equipment at the future moment.
For more details regarding predicted power generation characteristics and predicted power usage characteristics, see figures 3-4 and their associated description herein.
In some embodiments, the processor may select a candidate power supply policy having an optimal evaluation value from among a plurality of candidate power supply policies as the target power supply policy based on the evaluation value. That is, the processor may select the candidate power supply strategy with the lowest purchase cost (or the lowest ratio of purchase cost to power supply amount) as the target power supply strategy.
In the embodiment of the specification, the candidate power supply strategy with the optimal evaluation value is selected through simulation as the target power supply strategy, so that the electricity buying cost and the power supply quantity can be measured, the energy efficiency distribution management of the photovoltaic equipment is more balanced, and the stability of a power grid is ensured.
Step 240, determining a control command based on the power supply strategy, and controlling an operating state of at least one of the power generation device and the monitoring component based on the control command.
The control instructions may be instructions that the processor transmits to other components in the photovoltaic device so that the photovoltaic device may perform power distribution based on the power supply strategy. In some embodiments, the control instructions may include generated power, stored power, etc. of the power generation device, operating time of the monitoring component, etc.
In some embodiments, the operating state of the power generation device may include an operating state of the energy storage component (e.g., energy storage or discharging), an operating state of the photovoltaic power generation component (e.g., electrical energy output to the powered device or the energy storage component), and so on. In some embodiments, the operating state of the monitoring component may include on/off of the monitoring component, as well as a monitored object, a monitored time, etc. when the monitoring component is on. For more details of the power generation device and monitoring assembly, reference is made to FIG. 1 and its associated description.
For example, the processor may adjust whether the energy storage assembly is storing energy or discharging energy based on the control instruction, and control the photovoltaic power generation assembly to output electrical energy to the electrical device or the energy storage assembly, so that the photovoltaic device may generate power according to the power supply strategy. Or the processor can control the monitoring component to monitor the power generation device so as to ensure the normal operation of the power generation device.
In some embodiments, the processor may determine the blowing parameters of the blowing device from dust data of the photovoltaic power generation assembly.
