Detailed Description
For better understanding of the objects, technical solutions and effects of the present invention, the present invention will be further explained with reference to the accompanying drawings and examples. Meanwhile, the following described examples are only for explaining the present invention, and are not intended to limit the present invention.
The embodiment of the invention provides a power transmission path management method.
Fig. 1 is a flowchart illustrating a power transmission path management method according to an embodiment, and as shown in fig. 1, the power transmission path management method according to an embodiment includes steps S100 to S102:
s100, combing transmission topologies among the power generation node, the energy storage node and the power utilization node to obtain a power transmission path set; wherein the power transmission path includes a plurality of paths;
s101, dividing a power transmission path set into a high energy consumption path set and a low energy consumption path set according to the power throughput of an energy storage node;
and S102, adjusting the high-energy-consumption path set and the low-energy-consumption path set according to the generated energy of the power generation node and the power consumption of the power utilization node.
In the present embodiment, the purpose is to adjust the paths between the power generation node, the energy storage node, and the power utilization node, i.e., the power transmission path. It should be noted that the embodiment of the present invention is directed to a large-scale electricity utilization node, that is, the electricity consumption of the electricity utilization node is close to the power generation amount of the power generation node and the power throughput of the energy storage node. The power utilization node can be a large-scale substation or a high-energy-consumption power utilization facility in a geographic area.
The transmission topology among the power generation nodes, the energy storage nodes and the power utilization nodes takes the power generation nodes as a starting point and the power utilization nodes as an end point. The set of power transmission paths includes all paths from the start point to the end point.
In one embodiment, fig. 2 is a flowchart of a power transmission path management method according to another embodiment, and as shown in fig. 2, a process of combing transmission topologies among a power generation node, an energy storage node, and a power utilization node to obtain a power transmission path set in S100 includes step S200:
and S200, calculating a power transmission path set according to the product of the number of the power generation nodes and the number of the power utilization nodes.
And according to the data product of the power generation node and the power utilization node, the data product is used as the number of paths in the power transmission path set, so that the path number can be conveniently and approximately obtained.
In one embodiment, fig. 3 is a flowchart of a power transmission path management method according to yet another embodiment, and as shown in fig. 3, a process of combing transmission topologies among a power generation node, an energy storage node, and a power utilization node to obtain a power transmission path set in S100 includes step S300:
and S300, determining paths among the carding power generation node, the energy storage node and the power utilization node according to a Gaussian two-step search method.

The power generation node and the energy storage node are used as supply parties, and the power utilization node is used as a demand party. And determining a search boundary of the supplier and a demander in the search boundary by a Gaussian two-step search method.
Further, the transportation cost of a supplier and the transportation cost of a demander are searched by a Gaussian two-step search method, different paths are constructed according to the cost difference, and the power transmission path set is determined.
Based on the method, the transmission topology among the power generation node, the energy storage node and the power utilization node can be determined more accurately by a Gaussian two-step search method, and the paths of the power transmission path set are determined. And the demand side with more than certain transportation cost is eliminated, and the path is further simplified.
When the energy storage node exists in the path, the energy storage node stores the power generation of the power generation node, and then the working condition of supplying power to the power utilization node is existed, namely the power throughput of the energy storage node represents the whole energy consumption in the path, so that the method can be used for preliminarily dividing a high-energy-consumption path set and a low-energy-consumption path set. Wherein the energy consumption of the paths in the high energy consumption path set is higher than the energy consumption of the paths in the low energy consumption path set.

and S202, when the power throughput is larger than the preset power throughput, dividing the paths into a high-energy-consumption path set, otherwise, dividing the paths into a low-energy-consumption path set.
In one embodiment, the preset power throughput is a median or average of the power throughputs to preliminarily classify the set of power transmission paths.
Based on the above, the high energy consumption path set and the low energy consumption path set are adjusted according to the power generation amount of the power generation node and the power consumption of the power utilization node, and the paths in the high energy consumption path set are adjusted to the low energy consumption path set or the paths in the low energy consumption path set are adjusted to the high energy consumption path set.
In one embodiment, as shown in fig. 3, the process of dividing the set of power transmission paths into the set of high energy consumption paths and the set of low energy consumption paths according to the power throughput of the energy storage node in step S101 includes steps S301 to S303:
s301, acquiring transmission time of paths of the power transmission path set;
s302, sorting each path according to the product of the transmission time and the power throughput of the energy storage nodes in the paths of the power transmission path set;
and S303, dividing paths which are greater than or equal to the preset sequence in the sequence into a high energy consumption path set, and dividing paths which are smaller than the preset sequence into a low energy consumption path set.
In one embodiment, the transmission time is determined by selecting the characteristic signal at the power generation node, monitoring the characteristic signal at the power utilization node, and delaying the occurrence time of the characteristic signal in the power generation node and the occurrence time of the characteristic signal in the power utilization node. Wherein the characteristic signal comprises a power peak.
And sequencing each path according to the product of the power throughput of the energy storage nodes, and distinguishing the paths. Based on this, the fineness of the path classification by the power throughput in step S101 is further restricted by the transmission time, and the accuracy is improved.
In one embodiment, as shown in fig. 2, the process of adjusting the high energy consumption path set and the low energy consumption path set according to the power generation amount of the power generation node and the power consumption amount of the power consumption node in step S102 includes steps S203 and S204:
and S203, calculating classification values of all paths according to the generated energy and the power consumption, wherein the classification values are as follows:
Figure BDA0003375032740000081
wherein P (i) represents a time period i classification value, QiElectric power consumption amount, E, representing period iMaxRepresents the maximum value of the amount of electric power generation, EMinThe minimum value of the amount of power generation is expressed,
Figure BDA0003375032740000082
τ represents a correction coefficient;
and S204, dividing the paths in the time interval i which are larger than the corresponding classification values into a high-energy-consumption path set, and otherwise, dividing the paths into a low-energy-consumption path set.
The mode of step S203 and step S204 is convenient for quantitatively and accurately distinguishing the high energy consumption path set and the low energy consumption path set
In one embodiment, as shown in fig. 3, the process of dividing the power transmission path set into the high energy consumption path set and the low energy consumption path set according to the power throughput of the energy storage node in step S102 includes steps S304 and S305:
s304, performing OD cost matrix analysis by taking the power generation node as a starting point, the power utilization node as a terminal point and the difference value between the generated energy and the power consumption as the transportation cost;
and S305, determining paths within the economic allowable range according to the OD cost, dividing the paths into a low-energy-consumption path set, and taking the paths outside the economic allowable range as a high-energy-consumption path set.
And determining an economic allowable range by using the OD cost as a blocking parameter, and distinguishing a high energy consumption path set from a low energy consumption path set. Compared with the mode in the step S305, in the step S304, the high energy consumption path aggregation and the low energy consumption path aggregation are performed from the aspect of area matching, which is more convenient to adapt to the cross-area scene of power transmission in practical application, and improves the reference value.
