Abstract
Description
Technical Field
[0001] Embodiments of the present invention relate to the technical field of power systems, and in particular to a power control method, device, electronic device, and storage medium for a power system. Background Art
[0002] As the global energy mix accelerates its transition toward cleaner energy, the penetration of new energy generation systems like photovoltaics and wind power continues to rise within the power system. The intermittent and volatile nature of these systems, coupled with the rigid demand for real-time balance between power supply and demand, is becoming increasingly challenging. Against this backdrop, maximizing the absorption rate of new energy generation systems while ensuring a dynamic balance between power supply and demand has become a core technical challenge in the operation of new power systems.
[0003] Currently, traditional power system power control methods generally adopt a "grid-first" dispatching logic, which prioritizes relying on the grid for power regulation when load demand fluctuates (such as purchasing electricity from the grid to fill gaps or absorb excess power). However, this approach has two drawbacks: when load demand exceeds current output, the system directly uses the grid for power, resulting in insufficient utilization of renewable energy and a low renewable energy absorption rate; when load demand is less than current output, the system directly sends excess power back to the grid, causing some power to be wasted and unable to be absorbed.
[0004] Therefore, a new method is urgently needed to solve the above problems. Summary of the Invention
[0005] The present invention provides a power control method, device, electronic equipment and storage medium for an electric power system, which improve the absorption rate of new energy and the overall energy utilization efficiency while reducing resource waste.
[0006] In a first aspect, an embodiment of the present invention provides a power control method for a power system, wherein the power system includes a power supply system and a power consumption system, wherein the power supply system includes a new energy power generation system, an energy storage discharge system, and a power dispatching system, and the power consumption system includes a user power consumption system, an energy storage charging system, and a power dispatching system. The method includes:
[0007] Obtaining the actual power supply of the power supply system at the current moment, determining the actual power supply of the power supply system at the current moment as the planned power supply of the power supply system at the next moment, and obtaining the predicted power consumption of the power consumption system at the next moment through the switch;
[0008] Calculating the difference between the predicted power consumption and the planned power supply to obtain a power difference;
[0009] When the power difference is greater than zero, determining the supplementary power supply of the power supply system according to the power difference, and controlling at least one of the new energy power generation system, the energy storage and discharge system, and the power dispatching system to provide the supplementary power supply;
[0010] When the power difference is less than zero, the supplementary power of the power consumption system is determined according to the power difference, and at least one of the user power consumption system, the energy storage charging system and the power dispatching system is controlled to provide the supplementary power.
[0011] The technical solution of the embodiment of the present invention first obtains the actual power supply of the power supply system at the current moment, determines the actual power supply power at the current moment as the planned power supply power of the power supply system at the next moment, and obtains the predicted power supply power of the power consumption system at the next moment through the switch, providing a data basis for the subsequent calculation of the power difference. The difference between the predicted power consumption and the planned power supply power is then calculated to obtain the power difference, which realizes a quantitative assessment of the supply and demand balance state and provides important data support for determining the subsequent power system regulation strategy. It is then determined whether the power difference is greater than zero. If it is greater than zero, it indicates that the power demand at the next moment exceeds the power supply capacity and the power supply needs to be increased to make up for the shortfall. At this time, the supplementary power supply of the power supply system can be determined based on the power difference, and at least one of the new energy power generation system, the energy storage discharge system, and the power dispatching system can be controlled to provide the supplementary power supply, thereby achieving dynamic matching of the supply and demand gap and ensuring the supply and demand balance of the power system. At the same time, the system regulation cost is reduced through multi-resource coordinated scheduling, solving the problem that when the load demand exceeds the current output, the system directly calls on the power grid for power supply, resulting in insufficient utilization of new energy and low absorption rate. If it is not greater than zero, it is necessary to further determine whether the power difference is less than zero. If it is less than zero, it indicates that the power supply capacity at the next moment is greater than the power demand, and there is a risk of power surplus. At this time, it is necessary to balance supply and demand by increasing power consumption to avoid energy waste. That is, the supplementary power consumption of the power consumption system can be determined based on the power difference, and at least one of the user's power consumption system, energy storage charging system, and power dispatching system can be controlled to provide supplementary power, thereby ensuring the balance of supply and demand of the power system, realizing multi-resource coordinated control, reducing energy waste, and solving the problem of directly sending excess power back to the power grid when the load demand is less than the current output, resulting in some power not being absorbed and wasted. If it is not less than zero, it means that the power difference is equal to zero, which means that the power supply capacity at the next moment is naturally matched with the power demand. At this time, it can be determined that the supplementary power supply power of the power supply system and the supplementary power consumption of the power consumption system are both zero. There is no need to make additional adjustments to the power system, thereby avoiding ineffective adjustments, thereby reducing adjustment costs, reducing equipment losses and energy consumption, and extending equipment life.
[0012] In a second aspect, an embodiment of the present invention further provides a power control device for a power system, wherein the power system includes a power supply system and a power consumption system, wherein the power supply system includes a new energy power generation system, an energy storage discharge system, and a power dispatching system, and the power consumption system includes a user power consumption system, an energy storage charging system, and a power dispatching system. The device includes:

[0016] The second control module is used to determine the supplementary power of the power consumption system according to the power difference when the power difference is less than zero, and control at least one of the user power consumption system, the energy storage charging system and the power dispatching system to provide the supplementary power.
[0017] In a third aspect, an embodiment of the present invention further provides an electronic device, the electronic device comprising:
[0018] at least one processor; and a memory communicatively coupled to the at least one processor;
[0019] The memory stores a computer program that can be executed by the at least one processor, and the computer program is executed by the at least one processor so that the at least one processor can implement the power control method of the power system described in any one of the first aspects.
[0020] In a fourth aspect, an embodiment of the present invention further provides a storage medium comprising computer-executable instructions, wherein the computer-executable instructions, when executed by a computer processor, implement the power control method of the power system described in any one of the first aspects.
[0021] It should be noted that the above-mentioned computer instructions may be stored in whole or in part on a computer-readable storage medium. The computer-readable storage medium may be packaged together with the processor of the power control device of the power system, or may be packaged separately from the processor of the power control device of the power system, and this application does not limit this.

[0037] Figure 1 A flowchart of a power control method for an electric power system provided in an embodiment of the present invention, this embodiment is applicable to situations where the actual power of the electric power system needs to be adjusted according to the predicted demand power. The electric power system includes a power supply system and a power consumption system. The power supply system includes a new energy power generation system, an energy storage discharge system and a power dispatching system. The power consumption system includes a user power consumption system, an energy storage charging system and a power dispatching system. The method can be executed by a power control device of an electric power system, and the power control device of the electric power system can be implemented in hardware / software. The device can be integrated into an electronic device, for example, it can be installed in a computer, and the embodiment of the present invention does not limit this. Figure 1 As shown, the specific steps include:
[0038] Step 110: Obtain the actual power supply of the power supply system at the current moment, determine the actual power supply of the current moment as the planned power supply of the power supply system at the next moment, and obtain the predicted power consumption of the power consumption system at the next moment through the switch.
[0039] Specifically, the power supply system refers to the overall system that provides electrical energy to power-consuming devices or areas, including renewable energy generation systems, energy storage and discharge systems, and power dispatch systems. Actual power supply refers to the actual power output of the power supply system at the current moment. Planned power supply refers to the power the power supply system plans to output at the next moment. The power consumption system refers to the system that consumes electrical energy, including user power consumption systems, energy storage and charging systems, and power dispatch systems. Forecasted power consumption refers to the expected power consumption of the power consumption system at the next moment.
[0040] In the specific implementation, the actual power supply power of the power supply system at the current moment can be obtained through the power sensor installed on the power supply system, and it can be directly used as the planned power supply power of the power supply system at the next moment. At the same time, the prediction results of the predictive power consumption model can be obtained through the switch to obtain the predicted power consumption of the power consumption system at the next moment.
[0041] It should be noted that the predictive electricity consumption model is used to obtain predicted electricity consumption at various points in time on the current day. Its input data is the weather type (e.g., cloudy, rainy, sunny), date type (e.g., weekday, holiday), and ambient temperature, which have been collected in advance for each point in time. The predictive electricity consumption model is trained as follows: The weather type, date type, ambient temperature, and corresponding historical electricity consumption at each historical point in time are collected as a training dataset. A deep learning model consisting of convolutional, pooling, and fully connected layers is trained to produce the predictive electricity consumption model.
[0042] In addition, to improve the accuracy of the electricity consumption prediction model, after obtaining the weather type, date type, ambient temperature, and corresponding historical electricity consumption at each historical time point, the following data processing can be performed: First, random errors are added to the training data set. For example, assuming the original training data set contains 100 historical electricity consumption data, the error ratio is set to 5%. A random function is used to generate 100 random numbers that follow a standard normal distribution. Each random number is multiplied by the error ratio (5%) to obtain the actual error value. The error value is then superimposed on the original data to obtain the enhanced training data. Second, the average feature of two adjacent time points is calculated and used to update the original feature. For example, if the preset time interval is 15 minutes, the current time point is A (i.e., 10:00 on April 20, 2025), and the previous adjacent time point is B (i.e., 09:45 on April 20, 2025), three sets of raw data are collected at 5-minute intervals within the A and B time windows. The average of the ambient temperature of these three sets of data is used as the new ambient temperature feature, and the average of the historical power consumption of the three sets of raw data is used as the new historical power consumption feature. Finally, the processed data is used as the training dataset to train a deep learning model consisting of convolutional layers, pooling layers, and fully connected layers to obtain a predictive power consumption model.
[0043] In this embodiment, through the above steps, the planned power supply power and predicted power consumption of the power supply system at the next moment are obtained, which provides a data basis for the subsequent calculation of the power difference.
[0044] Step 120: Calculate the difference between the predicted power consumption and the planned power supply to obtain the power difference.
[0045] Specifically, the power difference refers to the algebraic difference between the predicted power consumption and the planned power supply power, reflecting the degree of imbalance in power supply and demand between the power supply system and the power consumption system.
[0046] In specific implementation, in actual applications, the power difference = predicted power consumption - planned power supply power.
[0047] In this embodiment, through the above steps, a quantitative assessment of the supply and demand balance state is achieved, providing important data support for determining the subsequent regulation strategy of the power system.
[0048] Step 130: Determine whether the power difference is greater than zero.
[0049] If it is greater, execute step 140 ; if it is not greater, execute step 150 .
[0050] In a specific implementation, after obtaining the power difference, the first step is to determine whether the power difference is greater than zero. If it is, it indicates that the power demand at the next moment exceeds the power supply capacity, and the power supply needs to be increased to fill the gap. At this time, the power supply system can determine the supplementary power supply based on the power difference, and control at least one of the new energy power generation system, energy storage and discharge system, and power dispatch system to provide supplementary power to ensure supply and demand balance. If it is not greater than zero, it is necessary to further determine whether the power difference is less than zero to determine whether there is an oversupply.
[0051] Step 140: Determine the supplementary power supply of the power supply system according to the power difference, and control at least one of the new energy power generation system, the energy storage and discharge system, and the power dispatching system to provide the supplementary power supply.
[0052] Specifically, supplementary power supply refers to the additional power provided by the power supply system to make up for the supply and demand gap when the power difference is greater than zero. A new energy power generation system refers to a system that uses renewable energy (such as solar energy, wind energy, hydropower, etc.) to generate electricity, which is used to provide a clean and sustainable power supply. For example, new energy power generation systems include photovoltaic power generation systems and wind power generation systems. An energy storage and discharge system refers to a system that releases previously stored electrical energy when needed. A power dispatching system refers to a system responsible for coordinating and managing power supply and demand. For example, a power dispatching system may include a power grid.
[0053] In a specific implementation, after determining that the power difference is greater than zero, it can be determined that the power demand at the next moment is greater than the power supply capacity, and the power supply needs to be increased to make up for the gap. At this time, the supplementary power supply of the power supply system can be determined based on the power difference, and at least one of the new energy power generation system, the energy storage discharge system, and the power dispatching system can be controlled to provide the supplementary power supply. Specifically, the power difference can be first determined as the supplementary power supply of the power supply system, and then it is determined whether the increaseable power generation of the new energy power generation system is not less than the supplementary power supply. If the increaseable power generation is not less than the supplementary power supply, the new energy power generation system is controlled to provide all the required supplementary power supply. If the increaseable power generation is less than the supplementary power supply, it is further determined whether the sum of the increaseable power generation of the new energy power generation system and the increaseable discharge power of the energy storage discharge system is not less than the supplementary power. If the sum of the two is not less than the supplementary power, the new energy power generation system and the energy storage discharge system are controlled to jointly provide the required supplementary power. If the sum of the two is less than the supplementary power, it is necessary to control the new energy power generation system, the energy storage discharge system, and the power dispatching system to jointly provide the required supplementary power. In addition, after determining that the incremental power generation is less than the supplementary power supply, the new energy power generation system and the power dispatching system can be directly controlled to jointly provide the required supplementary power supply, or the new energy power generation system, the energy storage discharge system and the power dispatching system can be directly controlled to jointly provide the required supplementary power supply.
[0054] In this embodiment, through the above steps, not only is dynamic matching of the supply and demand gap achieved, ensuring the supply and demand balance of the power system, but the system regulation cost is also reduced through multi-resource coordinated scheduling, solving the problem of the system directly calling the power grid for power supply when the load demand is greater than the current output, resulting in insufficient utilization of new energy and low absorption rate.
[0055] Step 150: Determine whether the power difference is less than zero.
[0056] If it is less than, execute step 160; if it is not less than, execute step 170.
[0057] In a specific implementation, after determining that the power difference is not greater than zero, it is necessary to further determine whether the power difference is less than zero. If it is less than zero, it indicates that the power supply capacity at the next moment is greater than the power demand, and there is a risk of power surplus. At this time, it is necessary to balance supply and demand by increasing power consumption to avoid energy waste. That is, the supplementary power consumption of the power consumption system can be determined based on the power difference, and at least one of the user's power consumption system, energy storage charging system, and power dispatching system can be controlled to provide supplementary power. If it is not less than zero, it means that the power difference is equal to zero, indicating that the power supply capacity and power demand at the next moment are naturally matched. At this time, it can be determined that the supplementary power supply power of the power supply system and the supplementary power consumption power of the power consumption system are both zero, and no additional adjustment of the power system is required.
[0058] Step 160: Determine the supplementary power consumption of the power consumption system according to the power difference, and control at least one of the user power consumption system, the energy storage charging system, and the power dispatching system to provide the supplementary power consumption.
[0059] Specifically, supplementary power refers to the additional power added by the power system to consume excess power when the power difference is less than zero. The user power consumption system refers to the system that directly consumes power. For example, the power consumption system can include household, industrial equipment and other power loads. The energy storage charging system refers to a system used to store electrical energy, which is used to absorb and store electrical energy when there is excess power. For example, the energy storage charging system can include energy storage devices (such as battery packs, flywheel energy storage, compressed air energy storage, etc.) and charging control equipment.
[0060] In a specific implementation, after determining that the power difference is less than zero, it can be determined that the power demand at the next moment is less than the power supply capacity. At this time, the power consumption needs to be increased to balance supply and demand and avoid energy waste. That is, the supplementary power consumption of the power consumption system can be determined based on the power difference, and at least one of the user power consumption system, the energy storage charging system, and the power dispatching system can be controlled to provide supplementary power. Specifically, the absolute value of the power difference can be first determined as the supplementary power consumption of the power supply system, and then it can be determined whether the increaseable power consumption of the user power consumption system is not less than the supplementary power consumption. If the increaseable power consumption is not less than the supplementary power consumption, the user power consumption system can be controlled to provide supplementary power. If the incremental power consumption is less than the supplementary power consumption, it is further determined whether the sum of the incremental power consumption of the user power consumption system and the incremental power consumption of the energy storage charging system is not less than the supplementary power consumption. If the sum of the two is not less than the supplementary power consumption, the user power consumption system and the energy storage charging system are controlled to jointly provide the required supplementary power consumption. If the sum of the two is less than the supplementary power consumption, it is necessary to control the user power consumption system, the energy storage charging system, and the power dispatching system to jointly provide the required supplementary power consumption. In addition, after determining that the incremental power consumption is less than the supplementary power consumption, the user power consumption system and the power dispatching system can be directly controlled to jointly provide the required supplementary power consumption, or the user power consumption system, the energy storage charging system, and the power dispatching system can be directly controlled to jointly provide the required supplementary power consumption.
[0061] In this embodiment, through the above steps, not only the supply and demand balance of the power system is ensured, but also multi-resource coordinated control is achieved, energy waste is reduced, and the problem of waste caused by the inability to absorb part of the electricity when the load demand is less than the current power generation output is effectively solved.
[0062] Step 170: Determine that the supplementary power supply power of the power supply system and the supplementary power consumption power of the power consumption system are both zero.
[0063] In the specific implementation, after determining that the power difference is zero, it can be determined that the power supply and demand at the next moment are in a balanced state, which means that the current power supply capacity fully meets the power demand. At this time, it can be determined that the supplementary power supply power of the power supply system and the supplementary power consumption power of the power consumption system are both zero, and no additional adjustments to the power system are required.
[0064] In this embodiment, the above steps can ensure stable operation of the system, avoid ineffective adjustment, and thus reduce adjustment cost expenditure, lower equipment loss and energy consumption, and extend the service life of the equipment.
[0065] In an embodiment of the present invention, the actual power supply of the power supply system at the current moment is first obtained, and the actual power supply power at the current moment is determined as the planned power supply power of the power supply system at the next moment. The predicted power supply power of the power consumption system at the next moment is obtained through the switch, providing a data basis for the subsequent calculation of the power difference. The difference between the predicted power consumption and the planned power supply power is then calculated to obtain the power difference, which achieves a quantitative assessment of the supply and demand balance state and provides important data support for determining the subsequent power system regulation strategy. It is then determined whether the power difference is greater than zero. If it is greater than zero, it indicates that the power demand at the next moment exceeds the power supply capacity and the power supply needs to be increased to fill the gap. At this time, the supplementary power supply of the power supply system can be determined based on the power difference, and at least one of the new energy power generation system, the energy storage and discharge system, and the power dispatching system can be controlled to provide the supplementary power, thereby achieving dynamic matching of the supply and demand gap and ensuring the supply and demand balance of the power system. At the same time, the coordinated scheduling of multiple resources reduces the system regulation cost and solves the problem of underutilization of new energy and low absorption rate caused by the system directly calling the power grid for power when the load demand exceeds the current output. If it is not greater than zero, it is necessary to further determine whether the power difference is less than zero. If it is less than zero, it indicates that the power supply capacity at the next moment is greater than the power demand, and there is a risk of power surplus. At this time, it is necessary to balance supply and demand by increasing power consumption to avoid energy waste. That is, the supplementary power consumption of the power consumption system can be determined based on the power difference, and at least one of the user's power consumption system, energy storage charging system, and power dispatching system can be controlled to provide supplementary power, thereby ensuring the balance of supply and demand of the power system, realizing multi-resource coordinated control, reducing energy waste, and solving the problem that when the load demand is less than the current output, the system directly returns excess power to the power grid, resulting in some power not being absorbed and wasted. If it is not less than zero, it means that the power difference is equal to zero, indicating that the power supply capacity at the next moment is naturally matched with the power demand. At this time, it can be determined that the supplementary power supply power of the power supply system and the supplementary power consumption of the power consumption system are both zero, and there is no need to make additional adjustments to the power system, thereby avoiding ineffective adjustments, thereby reducing adjustment costs, reducing equipment losses and energy consumption, and extending equipment life.
[0066] Figure 2 This is a flow chart of another power control method for an electric power system provided by an embodiment of the present invention. This embodiment is specific based on the above embodiment. In this embodiment, the method may further include:
[0067] Step 210: Obtain the actual power supply of the power supply system at the current moment, determine the actual power supply of the current moment as the planned power supply of the power supply system at the next moment, and obtain the predicted power consumption of the power consumption system at the next moment through the switch.
[0068] Step 211: Calculate the difference between the predicted power consumption and the planned power supply to obtain the power difference.
[0069] Step 212: Determine whether the power difference is greater than zero.
[0070] If it is greater, execute step 222; if it is not greater, execute step 213.
[0071] In specific implementations, after obtaining the power difference, the first step is to determine whether it is greater than zero. If it is, this indicates that the power demand at the next moment exceeds the power supply capacity, and the power supply needs to be increased to fill the gap. In this case, the power supply system's supplementary power can be determined based on the power difference, and the subsequent power system regulation strategy can be determined based on the supplementary power supply. If it is not greater than zero, it is necessary to further determine whether the power difference is less than zero to determine whether there is an oversupply.
[0072] Step 213: Determine whether the power difference is less than zero.
[0073] If it is less than, execute step 215; if it is not less than, execute step 214.
[0074] In specific implementations, after confirming that the power difference is not greater than zero, it is necessary to further determine whether the power difference is less than zero. If it is less than zero, this indicates that the power supply capacity at the next moment exceeds the power demand, posing a risk of power surplus. In this case, the supplementary power consumption of the power consumption system can be determined based on the power difference, and the power system regulation strategy can be determined accordingly. If it is not less than zero, the power difference is equal to zero, indicating that the power supply capacity at the next moment naturally matches the power demand. At this point, it can be determined that the supplementary power supply power of the power supply system and the supplementary power consumption of the power consumption system are both zero, eliminating the need for additional power system adjustments.
[0075] Step 214: Determine that the supplementary power supply power of the power supply system and the supplementary power consumption power of the power consumption system are both zero.
[0076] Step 215: Determine the supplementary power consumption of the power system according to the power difference.
[0077] Step 216: Determine whether the increaseable power consumption of the user's power consumption system is less than the supplementary power consumption.
[0078] If it is less than, execute step 218; if it is not less than, execute step 217.
[0079] Specifically, the increaseable power consumption of a user's power consumption system refers to the upper limit of the power consumption that can be actively increased in the user's power consumption equipment or load system. For example, the increaseable power consumption of a user's power consumption system includes the increaseable flexible load of the user's power consumption equipment.
[0080] In a specific implementation, after determining that the power difference is less than zero, the user's power consumption system's incremental power consumption at the current moment can be obtained and used as the incremental power consumption of the user's power consumption system at the next moment. Then, it is determined whether the incremental power consumption of the user's power consumption system is less than the supplementary power consumption. If it is not less than, it means that the capacity increase capability of the user's adjustable load is sufficient to cover all excess power. In this case, the user's power consumption system can be controlled to provide supplementary power. If it is less than, it means that the capacity increase capability of the user's adjustable load is insufficient to absorb all excess power. In this case, it is necessary to calculate the difference between the supplementary power consumption and the incremental power consumption to obtain the remaining power consumption, and determine the power system regulation strategy accordingly.
[0081] In this embodiment, the above steps provide a basis for determining the subsequent regulation strategy of the power system.
[0082] Step 217: Control the user's power consumption system to provide supplementary power.
[0083] In the specific implementation, after determining that the increaseable power consumption of the user's power consumption system is not less than the supplementary power consumption, it can be determined that the capacity expansion capacity of the adjustable load on the user side is sufficient to cover all excess power. At this time, the user's power consumption system can be directly controlled to provide supplementary power consumption.
[0084] In this embodiment, through the above steps, excess electricity can be directly absorbed by the user-side adjustable load without relying on energy storage or grid feedback, eliminating the risk of excess electricity not being used from the source. This not only maximizes the utilization of new energy and saves operating costs, but also reduces equipment losses and extends system life.
[0085] Step 218: Calculate the difference between the supplementary power and the incremental power to obtain the remaining power.
[0086] Specifically, the remaining power refers to the difference between the supplementary power and the increaseable power when the increaseable power is less than the supplementary power.
[0087] In a specific implementation, it can be determined that the remaining power consumption = the supplementary power consumption - the increaseable power consumption.
[0088] In this embodiment, through the above steps, the excess power that cannot be absorbed by the user's power consumption system is determined, providing a data basis for the subsequent determination of the regulation strategy of the power system.
[0089] Step 219: Determine whether the incremental charging power of the energy storage charging system is less than the remaining power.
[0090] If it is less than, execute step 221; if it is not less than, execute step 220.
[0091] Specifically, the increaseable charging power of the energy storage charging system refers to the upper limit of the charging power that can be safely and stably increased under the current operating state of the energy storage charging system.
[0092] In a specific implementation, after obtaining the remaining power, the current available power of the energy storage charging system can be obtained and used as the available power of the energy storage charging system at the next moment. It is then determined whether the available power of the energy storage charging system is less than the remaining power. If it is not less than, it means that the energy storage charging system can absorb the remaining power. In this case, the user's power consumption system and the energy storage charging system can be controlled to provide supplementary power. If it is less than, it means that the energy storage charging system cannot absorb the remaining power. In this case, it is necessary to control the user's power consumption system, the energy storage charging system, and the power dispatching system to provide supplementary power.
[0093] In this embodiment, the above steps provide a basis for determining the regulation strategy of the power system.
[0094] Step 220: Control the user's power consumption system and the energy storage charging system to provide supplementary power.
[0095] In a specific implementation, after determining that the incremental charging power of the energy storage charging system is not less than the remaining power consumption, it can be determined that the incremental charging power of the energy storage charging system is sufficient to cover all the remaining power consumption. At this time, the user's power consumption system and the energy storage charging system can be controlled to provide supplementary power.
[0096] In this embodiment, through the above steps, excess power that cannot be absorbed by user-side devices can be stored in the energy storage and charging system. This not only avoids overloading of user-side devices and improves their efficiency, but also enhances the efficiency and flexibility of the energy storage and charging system. Furthermore, it effectively avoids power waste caused by supply and demand imbalances, reduces unnecessary power dispatch operations, and thus reduces overall operating costs.
[0097] Step 221: Control the user's power consumption system, energy storage charging system, and power dispatching system to provide supplementary power.
[0098] In a specific implementation, after determining that the energy storage charging system's incremental charging power is less than the remaining power consumption, it can be determined that the energy storage charging system's incremental charging power is insufficient to cover all the remaining power consumption. In this case, it is necessary to control the user's power consumption system, the energy storage charging system, and the power dispatching system to provide supplementary power. The power dispatching system can provide supplementary power by feeding power back to the grid.
[0099] In this embodiment, the above steps can fully absorb excess power, avoiding power waste caused by supply-demand imbalances. Furthermore, by absorbing excess power in a tiered manner, system safety can be maintained while enhancing the flexibility of the power system, making it more resilient to emergencies or short-term load fluctuations.
[0100] In one embodiment, after determining that the incremental charging power of the energy storage charging system is less than the remaining power consumption, it is possible to determine whether the power dispatching system has a maximum reverse power; if not, the user power consumption system, the energy storage charging system, and the power dispatching system are directly controlled to provide supplementary power. If so, the difference between the remaining power consumption and the incremental charging power of the energy storage charging system is calculated to obtain the required power consumption, and it is determined whether the maximum reverse power is less than the required power consumption. If not, the user power consumption system, the energy storage charging system, and the power dispatching system are controlled to provide supplementary power. If it is less than, the planned power supply of the power supply system is reduced (such as reducing the power supply of the new energy system or reducing the power supply called by the power grid), so as to avoid exceeding the absorption capacity of the power dispatching system and improve the safety and stability of the system.
[0101] Step 222: Determine the supplementary power supply power of the power supply system according to the power difference.
[0102] Step 223: Determine whether the incremental power generation capacity of the new energy power generation system is less than the supplementary power supply capacity.
[0103] If it is less than, execute step 225; if it is not less than, execute step 224.
[0104] Specifically, the incremental power generation capacity of a renewable energy power generation system refers to the upper limit of the power generation capacity that can be increased in the current state of the renewable energy power generation system. For example, the incremental power generation capacity of a renewable energy power generation system includes the incremental power generation capacity of a photovoltaic power generation system and the incremental power generation capacity of a wind power generation system.
[0105] In a specific implementation, after determining that the power difference is greater than zero, the incremental power generation power of the new energy power generation system at the current moment can be obtained and used as the incremental power generation power of the new energy power generation system at the next moment, and then it can be determined whether the incremental power generation power of the new energy power generation system is less than the supplementary power supply power. If it is not less than, it means that the incremental power generation power of the new energy power generation system is sufficient to cover all power supply gaps. At this time, the new energy power generation system can be controlled to provide supplementary power supply power; if it is less than, it means that the incremental power generation power of the new energy power generation system is insufficient to cover all power supply gaps. At this time, it is necessary to calculate the difference between the supplementary power supply power and the incremental power generation power to obtain the power supply shortage margin, and determine the adjustment strategy of the power system accordingly.
[0106] In this embodiment, the above steps provide a basis for determining the regulation strategy of the power system.
[0107] Step 224: Control the new energy power generation system to provide supplementary power.
[0108] In specific implementation, after determining that the incremental power generation capacity of the new energy power generation system is not less than the supplementary power supply capacity, it can be determined that the incremental power generation capacity of the new energy power generation system can fully meet the power supply gap demand. At this time, the new energy power generation system is directly controlled to provide supplementary power supply capacity.
[0109] For example, if the new energy power generation system includes a photovoltaic power generation system and a wind power generation system, after determining that the incremental power generation capacity of the new energy power generation system is not less than the supplementary power supply capacity, a determination is made as to whether the incremental power generation capacity of the photovoltaic power generation system is less than the supplementary power supply capacity. If so, the photovoltaic power generation system and the wind power generation system are controlled to provide the supplementary power supply capacity. If not, the photovoltaic power generation system is controlled to provide the supplementary power supply capacity.
[0110] For example, if the new energy power generation system includes a photovoltaic power generation system and a wind power generation system, after determining that the incremental power generation capacity of the new energy power generation system is not less than the supplementary power supply capacity, it is determined whether the incremental power generation capacity of the wind power generation system is less than the supplementary power supply capacity. If so, the photovoltaic power generation system and the wind power generation system are controlled to provide the supplementary power supply capacity. If not, the wind power generation system is controlled to provide the supplementary power supply capacity.
[0111] In this embodiment, through the above steps, clean energy such as photovoltaic and wind power can be preferentially called upon, avoiding the phenomenon of new energy power abandonment caused by directly starting the energy storage discharge system or the power dispatching system, thereby maximizing the consumption of new energy, reducing the number of unnecessary charge and discharge times of energy storage, extending the service life of energy storage equipment, and saving electricity purchase costs.
[0112] Step 225: Calculate the difference between the supplementary power supply and the additional power supply to obtain the power supply shortage margin.
[0113] Specifically, the power supply deficit margin refers to the difference between the two when the incremental power generation power of the new energy power generation system is less than the supplementary power supply power, which is used to represent the remaining power gap.
[0114] In specific implementation, the power supply shortage margin = supplementary power supply power - additional power generation power.
[0115] In this embodiment, by calculating the power supply shortage margin, a data basis is provided for determining a subsequent adjustment strategy of the power system.
[0116] Step 226: Determine whether the increaseable discharge power of the energy storage discharge system is less than the power supply shortage margin.
[0117] If it is less than, execute step 227; if it is not less than, execute step 228.
[0118] Specifically, the increaseable discharge power of the energy storage discharge system refers to the upper limit of the discharge power that can be safely and stably increased under the current operating state of the energy storage discharge system.
[0119] In a specific implementation, after obtaining the power supply margin, the current available power of the energy storage discharge system can be obtained and used as the available power of the energy storage discharge system at the next moment. It is then determined whether the available power of the energy storage discharge system is less than the remaining power. If it is, the available power of the energy storage discharge system is sufficient to cover the power supply margin, and the new energy generation system and the energy storage discharge system can be controlled to provide supplementary power. If it is, the available power of the energy storage discharge system is insufficient to cover the power supply margin, and the new energy generation system, the energy storage discharge system, and the power dispatching system need to be controlled to provide supplementary power.
[0120] In this embodiment, the above steps provide a basis for determining the regulation strategy of the power system.
[0121] Step 227: Control the new energy power generation system, the energy storage discharge system, and the power dispatching system to provide supplementary power supply.
[0122] In a specific implementation, after determining that the energy storage discharge system's incremental discharge power is less than the power supply margin, it can be determined that the energy storage discharge system's incremental discharge power is insufficient to cover the power supply margin. In this case, it is necessary to control the new energy power generation system, the energy storage discharge system, and the power dispatching system to provide supplemental power. The power dispatching system can provide supplemental power by calling power from the grid.
[0123] In this embodiment, through the above steps, renewable energy generation systems and energy storage and discharge systems are prioritized to address power supply gaps, with the power dispatch system filling the smallest power gap only when necessary. This approach not only maximizes the utilization of renewable energy, but also ensures a balance between supply and demand, while avoiding power outages caused by overloading a single resource. Furthermore, it optimizes the power dispatch system's power dispatch costs (such as the cost of purchasing electricity from the grid) and avoids using electricity during periods of high electricity prices, thereby reducing the additional costs associated with power surges.
[0124] In one embodiment, after determining that the increaseable discharge power of the energy storage discharge system is less than the power supply shortage margin, it can be determined whether the power dispatching system has a maximum power supply; if not, the new energy power generation system, the energy storage discharge system, and the power dispatching system are directly controlled to provide supplementary power. If it exists, the difference between the power supply shortage margin and the increaseable discharge power of the energy storage discharge system is calculated to obtain the required power, and it is determined whether the maximum power supply power is not less than the required power supply. If not, the new energy power generation system, the energy storage discharge system, and the power dispatching system are controlled to provide supplementary power. If it is less, the planned power consumption of the user's power consumption system is reduced (such as reducing the flexible load or the cuttable load of the user's power consumption system), thereby avoiding problems such as the inability to fill the power supply gap, system frequency collapse, or equipment overload damage caused by insufficient power supply capacity of the power dispatching system.
[0125] Step 228: Control the new energy power generation system and the energy storage discharge system to provide supplementary power supply.
[0126] In a specific implementation, after determining that the increaseable discharge power of the energy storage discharge system is not less than the power supply shortage margin, it can be determined that the increaseable discharge power of the energy storage discharge system is sufficient to cover the entire power supply shortage margin. At this time, the new energy power generation system and the energy storage discharge system can be controlled to provide supplementary power supply.
[0127] In this embodiment, through the above steps, it is possible to maximize the utilization of clean energy, avoid using the power dispatching system to adjust power, reduce interaction pressure, and save electricity costs.
[0128] Therefore, the technical solution of the present invention first obtains the actual power supply of the power supply system at the current moment, determines the actual power supply power at the current moment as the planned power supply power of the power supply system at the next moment, and obtains the predicted power consumption of the power consumption system at the next moment through the switch, providing a data basis for the subsequent calculation of the power difference. The difference between the predicted power consumption and the planned power supply power is then calculated to obtain the power difference, which achieves a quantitative assessment of the supply and demand balance state and provides important data support for determining the subsequent power system regulation strategy. It is then determined whether the power difference is greater than zero. If the power difference is not greater than zero, it is necessary to further determine whether the power difference is less than zero to determine whether there is an oversupply. If the power difference is not less than zero, it means that the power difference is equal to zero, indicating that the power supply capacity at the next moment is naturally matched with the power demand. At this time, it can be determined that the supplementary power supply power of the power supply system and the supplementary power consumption of the power consumption system are both zero, and no additional adjustment of the power system is required. If the power difference is less than zero, it indicates that the power supply capacity at the next moment is greater than the power demand, and there is a risk of oversupply. In this case, the supplementary power consumption of the power consumption system can be determined based on the power difference. The user's power consumption system's incremental power consumption can then be determined to be less than the supplementary power consumption. If the incremental power consumption is not less than the supplementary power consumption, the user's power consumption system can be directly controlled to provide supplementary power. This maximizes the utilization of new energy, saves operating costs, reduces equipment losses, and extends system life. If the incremental power consumption is less than the supplementary power consumption, the difference between the supplementary power consumption and the incremental power consumption is calculated to obtain the remaining power consumption. The user's power consumption system can then be determined to be less than the remaining power consumption. If the incremental power consumption of the energy storage charging system is not less than the remaining power consumption, the user's power consumption system and the energy storage charging system can be controlled to provide supplementary power. This allows the excess power that cannot be absorbed by the user's equipment to be stored in the energy storage charging system. This not only prevents overload on the user's equipment and improves its efficiency, but also enhances the efficiency and flexibility of the energy storage charging system. This effectively avoids power waste caused by supply and demand imbalances, reduces unnecessary power dispatch operations, and ultimately reduces overall operating costs. If the energy storage charging system's incremental charging power is less than the remaining power consumption, the user's power consumption system, the energy storage charging system, and the power dispatching system will be controlled to provide supplementary power consumption, which can fully absorb the surplus power and avoid power waste caused by supply and demand imbalances. At the same time, by absorbing excess power at different levels, we can not only maintain the bottom line of system safety, but also enhance the flexibility of the power system, making it more capable of responding to emergencies or short-term load fluctuations. If the power difference is greater than zero, it indicates that the power demand at the next moment is greater than the power supply capacity, and the power supply needs to be increased to make up for the shortfall. At this time, the supplementary power supply of the power supply system can be determined based on the power difference. Then, it is determined whether the incremental power generation power of the new energy power generation system is less than the supplementary power supply power.If the incremental power generation capacity of the new energy power generation system is not less than the supplementary power supply capacity, the new energy power generation system is controlled to provide supplementary power supply, thereby maximizing the consumption of new energy, reducing unnecessary charging and discharging times of energy storage, extending the service life of energy storage equipment, and saving electricity purchase costs. If the incremental power generation capacity of the new energy power generation system is less than the supplementary power supply capacity, the difference between the supplementary power supply capacity and the incremental power generation capacity is calculated to obtain the power supply margin. Next, it is determined whether the incremental power generation capacity of the energy storage discharge system is less than the power supply margin. If the incremental power generation capacity of the energy storage discharge system is not less than the power supply margin, the new energy power generation system and the energy storage discharge system are controlled to provide supplementary power supply, thereby maximizing the utilization of clean energy, avoiding the use of the power dispatching system for power adjustment, reducing interaction pressure, and saving electricity costs. If the energy storage discharge system's incremental discharge power is less than the power supply shortfall, the renewable energy generation system, energy storage discharge system, and power dispatch system are controlled to provide supplemental power. This prioritizes the use of renewable energy generation and storage discharge systems to fill the power supply gap, with the power dispatch system filling the smallest power gap only when necessary. This maximizes the absorption of renewable energy, ensures a balance between supply and demand, and avoids power outages caused by overload of a single resource. Furthermore, this optimizes the power dispatch system's power dispatch costs (such as the cost of purchasing electricity from the grid) and avoids using electricity during high-price periods, thereby reducing the additional costs associated with power surges.
