Technical Field

Embodiments of the present disclosure relate to the field of computer technologies, and in particular, to a virtual power plant power flow method, apparatus, device, medium, and program product.

Background

A virtual power plant power transfer method is a technology for a virtual power plant to participate in power transfer. At present, when virtual power plant power circulation, the mode that usually adopts is: the virtual power plant directly adopts a background preset algorithm to generate data required by power flow declaration and carry out load decomposition to obtain a clearing curve corresponding to each energy device so that the virtual power plant can control each energy device to carry out load clearing according to the corresponding clearing curve. Thus, the virtual power plant completes the power flow.

However, the inventor finds that when the virtual power plant power flow is completed in the above manner, the following technical problems often exist:

firstly, in order to adapt to a constantly changing power flow mode of a virtual power plant, a background preset algorithm needs to be continuously optimized and adjusted, however, the background cannot be edited at the front end, so that the background preset algorithm is inconvenient to be optimized and adjusted, and the power flow accuracy of the virtual power plant is low;

secondly, due to the fact that virtual power plant power transfer modes are not uniform from place to place, background preset algorithms cannot be applied to various virtual power plant power transfer modes and lack of uniform custom algorithm interfaces, and therefore the universality of the virtual power plant power transfer method is low;

thirdly, when load decomposition is carried out, the difference of load adjusting capacities of different types of energy equipment is often easily ignored, and the influence of the new energy power generation power and the load prediction precision on the load decomposition is ignored, so that the accuracy of tracking a load clearing curve is low, and the power flow accuracy of a virtual power plant is low.

The above embodiments of the present disclosure have the following advantages: through the virtual power plant power flow method of some embodiments of the present disclosure, the accuracy of virtual power plant power flow can be improved. Specifically, the reasons for the low accuracy of power flow in the virtual power plant are: in order to adapt to the changing power transfer mode of the virtual power plant, the background preset algorithm needs to be continuously optimized and adjusted, however, the background cannot be edited at the front end, so that the background preset algorithm is inconvenient to be optimized and adjusted, and the power transfer accuracy of the virtual power plant is low. Based on this, the virtual power plant power flow method according to some embodiments of the present disclosure first generates an energy device information table for selecting each energy device information based on the declaration confirmation information in response to receiving declaration confirmation information for power flow declaration to-be-confirmed information. Therefore, the virtual power plant power flow declaration work can be started, and the class instance corresponding to each energy device can be conveniently generated subsequently by selecting each energy device participating in the declaration work. Secondly, in response to receiving energy device selection information aiming at each piece of energy device information in the energy device information table, instantiation processing is carried out on the energy device selection information, and a target energy device instance information set is obtained. Therefore, target energy equipment instance information corresponding to each energy equipment can be obtained, and algorithm interface information corresponding to the target energy equipment instance information set can be conveniently generated subsequently, and each subsequent algorithm can call the corresponding class instance. Therefore, the optimization and adjustment of the background preset algorithm can be facilitated. And determining the device type identifier corresponding to each piece of target energy device instance information in the target energy device instance information set as a target device type identifier to obtain a target device type identifier group. And determining the initial prompt information matched with each target equipment type identifier in the target equipment type identifier group in a preset initial prompt information set as the user prompt information to obtain a user prompt information group. Therefore, the equipment type of each energy equipment selected by the target user and the user prompt information corresponding to each equipment type can be obtained, and the subsequent target user can conveniently and correctly input information according to the prompt content. And then, generating first algorithm interface information based on the target energy equipment instance information set and the user prompt information set. And generating the next day load curve information based on the first algorithm interface information. Therefore, first algorithm interface information corresponding to the load generation algorithm can be obtained, and information input by a target user can be received through the first algorithm interface corresponding to the first algorithm interface information to optimize and adjust the load generation algorithm preset in the background, so that more accurate next-day load curve information can be obtained, and further, the next-day load curve information can be conveniently referred to in the follow-up process, and better power flow reporting strategy information can be generated. And then, generating second algorithm interface information based on the target energy equipment instance information set and the user prompt information set. And generating power flow declaration strategy information based on the next day load curve information and the second algorithm interface information. Therefore, second algorithm interface information corresponding to the price curve generation algorithm can be obtained, and information input by a target user can be received through the second algorithm interface corresponding to the second algorithm interface information to optimize and adjust the price curve generation algorithm preset in the background, so that more accurate electricity price curve information can be obtained, and further more excellent power flow declaration strategy information is generated for declaration. And finally, responding to the received information of the next-day birth-clearing curve, and generating third algorithm interface information based on the target energy equipment instance information set and the user prompt information set. And generating a target clearing curve information set for power circulation of the virtual power plant based on the next-day clearing curve information and the third algorithm interface information. Therefore, third algorithm interface information corresponding to the load decomposition algorithm can be obtained, and through the third algorithm interface corresponding to the third algorithm interface information, information input by a target user can be received to optimize and adjust the load decomposition algorithm preset in the background, so that more accurate target clearing curve information corresponding to each energy device can be obtained, each energy device can be controlled by the virtual power plant to carry out load clearing according to the corresponding target clearing curve information, and power circulation is completed. Therefore, the virtual power plant power flow method of the embodiment of the disclosure can realize optimization and adjustment of each background preset algorithm at the front end, so that more accurate next-day load curve information can be obtained conveniently for reference, more excellent power flow declaration strategy information can be generated for declaration, and more accurate target clearing curve information sets can be generated for the virtual power plant to control each energy device to execute power flow tasks strictly according to the corresponding target clearing curve information.

The problem that the power transfer accuracy of the virtual power plant is low is often as follows: when load decomposition is carried out, the difference of load adjusting capacities of different types of energy equipment is often easily ignored, and the influence of new energy power generation power and load prediction precision on load decomposition is ignored, so that the accuracy of tracking a load clearing curve is low, and the power flow accuracy of a virtual power plant is low. If the problem is solved, the effect of improving the accuracy of the power flow of the virtual power plant can be achieved. To achieve this effect, the present disclosure may divide energy devices with different load adjustment capabilities into different priorities by a prioritization method, so as to give full play to the new energy power generation capability when the load is decomposed, and to tend to distribute the power load task to the energy devices with stronger load adjustment capabilities.
