Description

Electronic device for controlling solar output power by high-efficiency harvesting control algorithm and control method of the electronic device

The present invention boosts the power that falls short of the target power, distributes it to the low-voltage harvesting circuit, stores it, and supplies it to the output circuit (which performs the output of the current stored in the low-voltage harvesting circuit) when the stored power reaches the target power. It is about an electronic device that controls the electrical output power of solar cells using a high-efficiency harvesting control algorithm, which provides a solution to improve the commercial efficiency of solar cells by increasing the power of generated electricity.

As a general method for boosting electricity, it is possible to boost the voltage to the target power in a boosting device, but continuously outputting and using the boosted electricity is a physical limitation.

It is possible to boost power with a general boosting device and harvesting device and store it in a storage device to output for a certain period of time, but charging this directly with a capacitor or battery is not continuous storage and charging, so primary power loss occurs. It is large, and the capacity of the charging element is also limited.

In addition, for both capacitors and batteries, there is inevitably a delay time between boosting the low power, outputting the accumulated power as the target power, and charging again. The phenomenon of such delay time is called the blank point and latency problem.

As a result, for capacitors with low charging capacity, the charging time and output time alternate briefly, while for high-capacity capacitors and batteries, the charging time and output time are slightly longer, and the charging time proceeds alternately after the output time, so the charging time alternates between the output time and the output time. A problem arises in which the same blank point phenomenon occurs. If this problem is partially solved and the section in which boosted power can be continuously output without interruption is expanded, the total production of generated electricity can be increased by continuously using the boosted power.

Meanwhile, the photoelectric conversion efficiency and actual commercial efficiency of conventional solar cells remain in the 20% range, so when fossil energy is replaced by solar energy, it is difficult to achieve the break-even point and secondary waste problems are bound to occur. .

In order to solve this problem, the improvement of energy generation efficiency will ultimately become the main key. By reducing the blank point occurrence time that occurs when powering up generated electricity, and improving the basic power generation of solar cells, the commercialization of solar power plants can be achieved. Methods to increase efficiency must be researched.

Meanwhile, the matters described as background technology above are only for the purpose of improving understanding of the background of the present application, and should not be taken as an acknowledgment that they correspond to prior art already known to those skilled in the art. .

Registered Patent Publication No. 10-2479198, December 15, 2022.

In order to solve the above-mentioned problem, the present invention arranges two or more capacitors that store the boosted low power and controls the stored power to be sequentially output without a blank point. At this time, the output power is sent back to the secondary capacitor and the battery. The purpose is to provide an electronic device and a control method for minimizing the crossing time of the blank point of the secondary output by storing it as .

As the steps according to our control method are repeated, the crossing time of the blank point is reduced, and the time for power to be output without interruption becomes longer. At the same time, the charge reduction induction function of the harvesting element improves the solar cell and our electronics. As the charge difference increases when devices are connected, the amount of power output from the solar cell increases through the drop phenomenon.

According to the results of our research on electronic devices, the power output of a 300W solar cell in an environment with an illuminance of 5,000 Lux (10 LED daylight lights, emitting a total of 1200W of light, and adjusting the distance to set the illuminance) was 11W, but Harves It was confirmed that when three powering elements were divided and connected in parallel, the primary output of the solar cell increased to 13.7W, and when the power was boosted by applying three boosting elements, the final power output was 15.4W. It was confirmed that there was improvement, and it was confirmed that no interruption occurred and continuous charging was achieved using our control method.

As for the second communication module, a detailed description thereof will be omitted since the communication module has been previously described.

The manager terminal may include a display, and the display may include various displays and may include a touch screen display.

Meanwhile, the memory may store at least one artificial intelligence model among a first artificial intelligence model and a second artificial intelligence model.

Specifically, the first artificial intelligence model is based on first learning data that includes at least one of the output value of the high-power harvesting circuit, the output time of the high-power harvesting circuit, the amount of sunlight per hour, and the blank point occurrence time when the output of power is cut off. Based on this, it may be an artificial intelligence model learned to calculate the minimum target power of the high-power harvesting circuit for the real-time solar amount and the predicted solar amount in the critical time range, solar data, and the rate of change of the output value.

The second artificial intelligence model is based on second learning data including at least one of the output value of the low-power harvesting circuit, the output time of the low-power harvesting circuit, the amount of sunlight per hour, and the blank point occurrence time, solar data, and output value. It may be an artificial intelligence model learned to calculate the minimum target power of a low-power harvesting circuit for a change rate of .

Accordingly, the memory may include instructions for causing the processor to perform the following control steps.

Specifically, when the manager terminal performs the control steps, when the manager terminal receives the first output value from the electronic device 100, the first output value for the first harvesting circuit 130 is based on the first output value. The rate of change can be updated.

Thereafter, the manager terminal inputs the updated rate of change of the first output value and real-time solar data into the first artificial intelligence model, and provides control data for the first target power calculated based on the output of the first artificial intelligence model. By transmitting to the electronic device 100, the upper limit of the first harvesting circuit 130 can be variably applied depending on the amount of sunlight, thereby preventing an increase in the generation time of the blank point due to a change in the amount of generated energy according to the amount of sunlight. there is.

At this time, when receiving the second output value from the electronic device 100, the manager terminal updates the rate of change of the second output value for the second harvesting circuit 140 based on the second output value, and updates the updated second output value. The rate of change and real-time solar data can be input into the second artificial intelligence model.

Accordingly, the manager terminal transmits control data for the larger value of the second target power and the first target power calculated based on the output of the second artificial intelligence model to the electronic device 100, thereby By limiting the upper limit of power distribution to the harvesting circuit based on the target power, the probability that the occurrence time of the blank point increases can be reduced.

Meanwhile, when performing control steps according to various embodiments of the present application, the manager terminal identifies a first time period in which a blank point occurs, where the time when both the first output value and the second output value are not received exceeds the threshold time. can do.

Accordingly, the manager terminal selects at least one target power included in the control data in the second time zone, which is a certain period before the first time zone, as error data, and calculates a weight proportional to the time interval in the first time zone. You can.

The manager terminal generates correction data that is increased by applying a weight to each of at least one target power included in the error data, and creates a first artificial intelligence model based on the solar data matching the second time zone and the correction data. , and by retraining at least one of the second artificial intelligence models, the previously learned content about the target power at a certain time (second time zone) that influenced the time at which the blank point occurred (first time zone) By making corrections, the reliability of the output of each artificial intelligence model can be automatically increased.

At this time, if the target power included in the error data is all the target power for the first harvesting circuit 130, the manager terminal retrains only the first artificial intelligence model through the correction data, and the error data is used for the second harvesting circuit 130. When including the target power for the circuit 140, both the first artificial intelligence model and the second artificial intelligence model can be retrained through the correction data.

By way of example, when the first time zone is identified, the manager terminal calculates an average output value, which is all first output values received in the second time zone, and an average value of all second output values, and all first output values received in the second time zone. Among the output values and all second output values, a maximum value and a minimum value can be identified.

At this time, if the second time zone does not include the sunset time zone or the sunrise time zone, the manager terminal calculates the difference value between the maximum value and the minimum value, and if the difference value exceeds the threshold difference value, it is determined that there is a third variable, By not performing retraining of the artificial intelligence model, it is possible to prevent a decrease in the reliability of the artificial intelligence model due to incorrect learning data.

Meanwhile, in performing control steps according to various embodiments of the present application, the manager terminal determines the predicted amount of sunlight in the critical time range based on weather data (e.g., weather information received from a previously connected weather server, etc.). Light prediction data can be identified.

Accordingly, the manager terminal may select the reference power for each time period based on solar power prediction data, the accumulated output of the first artificial intelligence model, and the accumulated output of the second artificial intelligence model.

Thereafter, the manager terminal compares the reference power, first target power, and second target power for each time zone and transmits control data for a larger value to the electronic device 100, thereby increasing the blank point to match the predicted amount of sunlight. A target power that is expected to generate less can be automatically applied.

In an embodiment, the electronic device 100 is in communication with at least one second electronic device 100 and includes a shared line for selectively sharing power, and the communication module communicates with the second electronic device and 1 Shared data including the output value of the harvesting circuit 130 (first output value), the output value of the second harvesting circuit 140 (second output value), and the preset identification code of the electronic device 100 are transmitted to the second harvesting circuit 130. It can be transmitted, received, and stored with an electronic device.

Specifically, based on the identification code included in the shared data and the output values matching the identification code, the control circuit 110 controls the third electronic device to which power less than the target power is input than the threshold time among the second electronic devices. Electronic devices can be identified, and among the third electronic devices, a fourth electronic device whose total amount of boosted power during a critical time is less than the target power can be identified.

Accordingly, when the fourth electronic device is identified, the power supplied to the first harvesting circuit 130 exceeds the target power, or the storage amount of the charging circuit 160 is greater than a threshold ratio of the maximum storage amount, the control circuit 110 ), it is possible to output the amount of power exceeding the target power or the power for the storage amount exceeding the threshold ratio of the maximum storage amount to the fourth electronic device through the shared line.

At this time, the electronic device 100 includes a storage module (memory), and the control circuit 110 does not store data containing an output value greater than the target power among the shared data, and does not store data containing an output value less than the target power. Only data is stored, but when data containing an output value higher than the target power is received for each identification code, the capacity of the storage module can be efficiently managed by deleting all data matching the corresponding identification code.

In an embodiment, when a plurality of fourth electronic devices are identified, the control circuit 110 selects the fifth electronic device with the shortest shared line length among the fourth electronic devices based on the identification code of each of the fourth electronic devices. By selecting a device and supplying power to the fifth electronic device, the efficiency of power supply can be increased.

In an embodiment, the shared line has one end connected to the charging circuit 160 of the electronic device 100, the other end includes a second low-power harvesting element, and the other end is connected to the charging circuit of the second electronic device. Thus, the power supplied to the fourth electronic device can be boosted.
