Description

Technical Field

[0001] The present invention relates to the technical field of power grid resource allocation, and in particular to a method, system and medium for allocating resources in a distribution network for load transfer. Background Art

[0002] As the power supply capacity of the power grid is increased at full speed, the mismatch between the progress of power grid construction and the needs of power security and social electricity demand is becoming more and more obvious; with the growth of regional GDP, social electricity demand increases; the problem of "hollowing out" of power sources is prominent, and it is difficult to balance power supply and demand during periods of high load; there is an imbalance in the development of the power grid and the load distribution is uneven.

[0003] At present and in the future, the structure and form of the power grid will gradually change, and the power grid cognition, control, and defense systems will face all-round challenges, which will put forward higher requirements for the optimal allocation of power resources and the dispatching and operation of the power grid. Therefore, how to establish intelligent power grid dispatching and operation control means, activate all kinds of resources in the whole network, improve flexible dispatching capabilities, collaborative interaction capabilities, and resource conditions, and how to comprehensively improve the control ability and safe operation level of large power grids have become key issues to be solved at present.

[0004] At present, there are deficiencies in the technical means of grid operation; the grid is in a transition period of rapid construction, and the grid topology has changed greatly. During the transition period, the local grid structure has weakened, the operation characteristics are complex and changeable, the control difficulty is becoming increasingly complex, and the power balance mode has changed. Faced with a large number of dispatching and control objects and operation mode adjustments, traditional grid operation and management methods are difficult to support the new business needs, and are even more unable to cope with the explosive growth in workload during the peak summer load period and continuous extreme weather conditions. Summary of the invention

[0005] The technical problem to be solved by the present invention is: during peak load periods and extreme weather conditions, the power supply capacity of the power grid is limited, the load transfer mode of the distribution network is chaotic and fragmented, and the traditional transfer resource scheduling method is difficult to timely adjust the load resources; the purpose of the present invention is to provide a distribution network resource allocation method for load transfer, to improve the method of traditional transfer resource scheduling technology, to formulate multiple groups of distribution network transfer modes based on a single transfer mode or a combined transfer mode, to fully enhance the power supply capacity of the power grid and the flexible mutual assistance capabilities between regions, to promote resource sharing, and to alleviate the problem of temporal and spatial mismatch between supply and demand.

[0006] The present invention is achieved through the following technical solutions:

[0007] This solution provides a method for allocating resources of a distribution network for load transfer, including:

[0008] Obtain data on the busbar to be transferred, the capacity to be transferred, and the distribution network lines;

[0009] Preprocessing the distribution network line data;

[0010] Based on the pre-processed distribution network line data, multiple groups of distribution network transfer modes are formulated based on a single transfer mode or a combined transfer mode to match the capacity to be transferred and the bus to be transferred; the transfer modes include: full line transfer mode, partial line transfer mode and hierarchical transfer mode;

[0011] The plurality of distribution network transfer modes are verified respectively, and distribution network resources are transferred according to the verified distribution network transfer modes.

[0012] Working principle of this scheme: During peak load periods and extreme weather conditions, the power supply capacity of the power grid is limited, the load transfer mode of the distribution network is chaotic and fragmented, and the traditional transfer resource scheduling method is difficult to adjust the load resources in a timely manner; the purpose of the present invention is to provide a distribution network resource allocation method for load transfer, to improve the method of traditional transfer resource scheduling technology, to formulate multiple groups of distribution network transfer modes based on a single transfer mode or a combined transfer mode, to fully enhance the power supply capacity of the power grid and the flexible mutual assistance capabilities between regions, to promote resource sharing, and to alleviate the problem of temporal and spatial mismatch between supply and demand.

[0013] In addition, this solution is not only for the distribution network resource allocation, but also for the main power network resource allocation according to the method of this solution.

[0014] A further optimization scheme is that the distribution network line data is preprocessed, including a method of: removing single radial lines and listed lines in the distribution network lines.

[0015] A further optimization scheme is that multiple groups of distribution network transfer modes are formulated based on a single transfer mode or a combined transfer mode to match the capacity to be transferred and the bus to be transferred, including the following method:

[0016] The following judgment is made on the capacity to be transferred:

[0017] When the capacity to be transferred is in the threshold interval A, the distribution network transfer mode is preferentially formulated based on a single transfer mode; wherein, when the capacity to be transferred is in the threshold interval A1, the distribution network transfer mode is preferentially formulated based on a full-line transfer mode or a partial-line transfer mode; when the capacity to be transferred is in the threshold interval A2, the distribution network transfer mode is preferentially formulated based on a hierarchical transfer mode;

[0018] When the capacity to be transferred is within the threshold interval B, the distribution network transfer method is formulated based on the combined transfer method first;

[0019] Among them, the capacity of threshold interval A is smaller than the capacity of threshold interval B; the capacity of threshold interval A1 is smaller than the capacity of threshold interval A2, and threshold interval A1 and threshold interval A2 are both located within threshold interval A.

[0020] Each threshold interval in this solution can be preset, or can be adaptively matched according to the capacity to be transferred and the transfer conditions.

[0021] A further optimization scheme is that the full-line transfer method includes: transferring all the capacity to be transferred to a substation in the distribution network;

[0024] The hierarchical transfer method includes at least two levels of transfer substations: the substation that directly receives the transferred capacity of the busbar to be transferred is the first-level transfer substation, and the substation that receives the transferred capacity of the first-level transfer substation is the second-level transfer substation.

[0025] A further optimization scheme is that the capacity to be transferred is transferred in stages to multiple substations of the distribution network in a flexible manner, including method A or method B;

[0026] Method A: When the capacity to be transferred is transferred to the first-level transfer substation, which will cause the load of the first-level transfer substation to exceed the limit, the capacity of the first-level transfer substation is first moved to the second-level transfer substation based on the full-line transfer mode or the partial-line transfer mode, and then the capacity to be transferred is transferred to the first-level transfer substation in the full-line transfer mode;

[0027] Method B: When the transfer of the capacity to be transferred to the first-level transfer substation will cause the load of the first-level transfer substation to exceed the limit, the capacity of the first-level transfer substation will be first transferred to the second-level transfer substation through the full-line transfer method or the partial-line transfer method, and then the capacity to be transferred will be transferred to different first-level transfer substations in the distribution network through the partial-line transfer method.

[0028] A further optimization scheme is that for method B, it also includes:

[0029] After the capacity of the first-level transfer substation is transferred to the second-level transfer substation through the full-line transfer method or the partial-line transfer method, if the transfer capacity is transferred to the first-level transfer substation, the load of the first-level transfer substation will still exceed the limit; adjust the proportion of partial capacity allocation of the partial-line transfer method until the load of the first-level transfer substation does not exceed the limit.

[0030] A further optimization scheme is that the multiple groups of distribution network transfer modes are verified respectively, including the following method:

[0031] S1, on the distribution network side, topologically link the current distribution network transfer mode with the bus side to be transferred, and determine whether the upper-level equipment on the distribution network side has load over-limit after the topological link. If not, enter step S2, otherwise, determine that the current distribution network transfer mode has not passed the verification;

[0032] S2, on the side of the bus to be transferred, it will be topologically linked with the distribution network according to the current distribution network transfer mode, and it will be determined whether the upper-level equipment on the side of the bus to be transferred has load exceeding the limit after the topological link. If not, it is determined that the current distribution network transfer mode has passed the verification.

[0033] The present solution also provides a load transfer distribution network resource allocation system, which is used to implement the above-mentioned load transfer distribution network resource allocation method, and the system includes:

[0034] The acquisition module is used to obtain the data of the busbar to be transferred, the capacity to be transferred, and the distribution network line;

[0050] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0051] Example 1

[0052] This embodiment provides a method for allocating resources of a distribution network for load transfer, such as Figure 1 As shown, including:

[0053] Step 1, obtaining the bus to be transferred, the capacity to be transferred, and the distribution network line data;

[0054] Step 2: preprocessing the distribution network line data; the preprocessing of the distribution network line data,

[0055] The method includes: eliminating single radial lines and listed lines in the distribution network.

[0056] Step 3: Based on the pre-processed distribution network line data, multiple groups of distribution network transfer modes are formulated based on a single transfer mode or a combined transfer mode to match the capacity to be transferred and the bus to be transferred; the transfer modes include: full line transfer mode, partial line transfer mode and hierarchical transfer mode;

[0057] The method of formulating multiple groups of distribution network transfer modes based on a single transfer mode or a combined transfer mode to match the capacity to be transferred and the bus to be transferred includes:

[0058] The following judgment is made on the capacity to be transferred:

[0059] When the capacity to be transferred is in the threshold interval A, the distribution network transfer mode is preferentially formulated based on a single transfer mode; wherein, when the capacity to be transferred is in the threshold interval A1, the distribution network transfer mode is preferentially formulated based on a full-line transfer mode or a partial-line transfer mode; when the capacity to be transferred is in the threshold interval A2, the distribution network transfer mode is preferentially formulated based on a hierarchical transfer mode;

[0060] When the capacity to be transferred is within the threshold interval B, the distribution network transfer method is formulated based on the combined transfer method first;

[0061] Among them, the capacity of threshold interval A is smaller than the capacity of threshold interval B; the capacity of threshold interval A1 is smaller than the capacity of threshold interval A2, and threshold interval A1 and threshold interval A2 are both located within threshold interval A.

[0062] Each threshold interval in this solution can be preset, or can be adaptively matched according to the capacity to be transferred and the transfer conditions.

[0063] For example, if the current supply and demand of the system is not tight and the capacity to be transferred is small, the load transfer on the main grid side can be transferred out by full-line transfer or partial-line transfer. During periods of high load, the capacity to be transferred is large, and the load in the target area needs to be transferred out before the load in the out-of-limit area is transferred to the target area. Therefore, it is necessary to formulate a distribution network transfer method based on a combined transfer method.

[0064] like Figure 2 As shown, the full-line transfer method includes: transferring all the capacity to be transferred to a substation in the distribution network;

[0065] like Figure 3 As shown, the partial line transfer method includes: dividing the capacity to be transferred into multiple partial capacities, and transferring each of the divided partial capacities to different substations in the distribution network respectively.

[0066] The hierarchical transfer method includes: hierarchically transferring the capacity to be transferred to multiple substations of the distribution network in a flexible manner;

[0067] The hierarchical transfer method includes at least two levels of transfer substations: the substation that directly receives the transferred capacity of the busbar to be transferred is the first-level transfer substation, and the substation that receives the transferred capacity of the first-level transfer substation is the second-level transfer substation.

[0068] The step of transferring the capacity to be transferred to multiple substations of the distribution network in a hierarchical manner includes method A or method B;

[0069] Method A: When the capacity to be transferred is transferred to the first-level transfer substation, which will cause the load of the first-level transfer substation to exceed the limit, the capacity of the first-level transfer substation is first moved to the second-level transfer substation based on the full-line transfer mode or the partial-line transfer mode, and then the capacity to be transferred is transferred to the first-level transfer substation in the full-line transfer mode;

[0070] Method B: When the transfer of the capacity to be transferred to the first-level transfer substation will cause the load of the first-level transfer substation to exceed the limit, the capacity of the first-level transfer substation will be first transferred to the second-level transfer substation through the full-line transfer method or the partial-line transfer method, and then the capacity to be transferred will be transferred to different first-level transfer substations in the distribution network through the partial-line transfer method.

[0071] For method B, it also includes:

[0072] After the capacity of the first-level transfer substation is transferred to the second-level transfer substation through the full-line transfer method or the partial-line transfer method, if the transfer capacity is transferred to the first-level transfer substation, the load of the first-level transfer substation will still exceed the limit; adjust the proportion of partial capacity allocation of the partial-line transfer method until the load of the first-level transfer substation does not exceed the limit.

[0073] like Figure 4 As shown, this embodiment provides a two-stage transfer example. The transfer of power from station C to station B will cause station B to exceed the limit. Before the transfer, a part of the load of station B needs to be transferred out (first perform the second-stage transfer), and then the load of station C is transferred to station B (later perform the first-stage transfer), and finally the following is obtained: Figure 5 The transfer scheme shown.

[0074] like Figure 6 and Figure 7 As shown, this embodiment provides a multi-level power transfer example and a power transfer solution.

[0075] Step 4: Verify the multiple groups of distribution network transfer modes respectively, and transfer the distribution network resources according to the distribution network transfer modes that have passed the verification. The specific method includes:

[0076] S1, on the distribution network side, topologically link the current distribution network transfer mode with the bus side to be transferred, and determine whether the upper-level equipment on the distribution network side has load over-limit after the topological link. If not, enter step S2, otherwise, determine that the current distribution network transfer mode has not passed the verification;

[0077] S2, on the side of the bus to be transferred, it will be topologically linked with the distribution network according to the current distribution network transfer mode, and it will be determined whether the upper-level equipment on the side of the bus to be transferred has load exceeding the limit after the topological link. If not, it is determined that the current distribution network transfer mode has passed the verification.

[0078] Example 2

[0079] This embodiment provides a load transfer distribution network resource allocation system, which is used to implement a load transfer distribution network resource allocation method of embodiment 1, such as Figure 8 As shown, the system comprises:

[0080] The acquisition module is used to obtain the data of the busbar to be transferred, the capacity to be transferred, and the distribution network line;

[0081] A preprocessing module, used for preprocessing the distribution network line data;

[0082] A planning module is used to plan multiple groups of distribution network transfer modes based on the preprocessed distribution network line data, based on a single transfer mode or a combined transfer mode, so as to match the capacity to be transferred and the bus to be transferred; the transfer modes include: full line transfer mode, partial line transfer mode and hierarchical transfer mode;

[0083] The verification allocation module is used to verify the multiple groups of distribution network transfer modes respectively, and transfer the distribution network resources according to the distribution network transfer modes that have passed the verification.

[0084] Example 3

[0085] This embodiment provides a computer-readable medium having a computer program stored thereon, wherein the computer program is executed by a processor to implement a method for allocating resources of a distribution network for load transfer as described in Embodiment 1, specifically performing the following steps:

[0086] Step 1, obtaining the bus to be transferred, the capacity to be transferred, and the distribution network line data;

[0087] Step 2: preprocessing the distribution network line data; the preprocessing of the distribution network line data,

[0088] The method includes: eliminating single radial lines and listed lines in the distribution network.

[0089] Step 3: Based on the pre-processed distribution network line data, multiple groups of distribution network transfer modes are formulated based on a single transfer mode or a combined transfer mode to match the capacity to be transferred and the bus to be transferred; the transfer modes include: full line transfer mode, partial line transfer mode and hierarchical transfer mode;

[0090] In this embodiment, after the distribution network bus obtains the capacity to be transferred, the connection relationship of the distribution lines on the bus is identified, and whether the distribution network can meet the transfer quantity requirements is calculated; the opposite line of the target transfer line in the distribution network is analyzed one by one to see if there are defects or placards, and whether the first-level 110kv main transformer of the distribution network has a transfer margin. If the safety conditions are met, the load of the line to be transferred is maximized. If there are defects or placards, the target transfer line is replaced. If the target transfer line in the distribution network operates normally and does not cause new over-limits, this transfer plan is recorded; if it may cause the opposite line to exceed the limit, the distribution network topology is used to reduce the amount of the line to be transferred or transfer the load to other connecting lines, or transfer the load of the target transfer line to the contact sequence of the target line, and then transfer it.

[0091] If the safety conditions are not met after the transfer on this side and the transfer on the opposite side, then other target transfer lines will be replaced, and the new opposite side line will be iteratively analyzed. If it meets the safety conditions, it will be transferred out. If it still does not meet the conditions, the iteration will continue.

[0092] After obtaining the final distribution network transfer mode through step 4, the distribution network interacts with the main network, and the main network side program analyzes each transfer of the distribution network one by one to see if it will cause new over-limit. If it meets the safety requirements, the distribution network transfer plan is approved. If not, this plan is deleted. If the remaining plans meet the target transfer volume, the satisfied plans will be sent to the distribution network for execution. If not, the new difference to be transferred is calculated and sent to the distribution network for re-iteration to form the optimal distribution network plan, which is reported to the main network again, and the above steps are repeated until it passes the verification of the upper power grid. If the iteration is terminated and the transfer volume cannot be absorbed, the load gap line is sent up and down to the marketing load control system.

[0093] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
