Description
Technical Field
[0001] The present invention relates to the technical field of power grid control, and in particular to a method and terminal for coordinated dispatching of power-traffic coupling taking into account the topology of a traffic network. Background Art
[0002] The global fossil energy crisis is attracting more and more attention, the widespread use of electric vehicles is still accelerating, and the rapid growth of electric vehicle ownership has made the connection between the power grid and the urban transportation network closer. Therefore, it is crucial to coordinate the dispatch of the power grid and the transportation network to achieve the optimal operation of the coupled system.
[0003] At present, the power dispatching of the power grid and the traffic dispatching of the transportation network are usually handled separately. This split dispatching mode can easily lead to power line overload and traffic congestion when facing the scenario of large-scale access to the power grid for charging of electric vehicles. On the one hand, as an important load of the power system, electric vehicles may uncontrollably choose the same charging station when charging their batteries during peak hours, resulting in over-limit of power line feed, which has an adverse impact on the safety and economic operation of the power system. On the other hand, a large number of electric vehicles may queue up near the same charging station at the same time, which not only increases the burden on the power system, but also easily leads to traffic jams near the charging station. Therefore, electric vehicles play a vital role in coupling the two systems. By reasonably guiding the charging behavior of electric vehicles, it is expected to significantly reduce the congestion and cost of the power grid and transportation network.
[0004] Although there have been studies dedicated to solving the problem of coordinated scheduling of electric-transport coupling and exploring the flexibility of electric vehicles and charging stations in the transportation network, these studies generally ignore the flexibility of the transportation network topology. In existing studies, the transportation network topology is often regarded as a fixed factor, but in fact, the topology of the transportation network can be reconstructed through strategies such as roadblock setting, personnel guidance, and signal light control. Therefore, in the problem of coordinated scheduling of electric-transport coupling, the use of transportation network topology reconstruction to improve the performance of the overall system has not been fully considered. Summary of the invention
[0005] The technical problem to be solved by the present invention is to provide an electric-traffic coupling coordinated scheduling method and terminal taking into account the topology of the transportation network, which realizes the redistribution of traffic flow through the topological reconstruction of the transportation network, thereby guiding the charging behavior of electric vehicles and reducing the power generation cost of the power grid and the travel cost of the transportation network.

[0007] In order to solve the above technical problems, another technical solution adopted by the present invention is: A terminal for coordinated dispatching of electric and traffic coupling taking into account the topology of a traffic network comprises a memory, a processor and a computer program stored in the memory and running on the processor. When the processor executes the computer program, each step of the above-mentioned method for coordinated dispatching of electric and traffic coupling taking into account the topology of a traffic network is implemented.

The operation cost is solved by the traffic system dispatching model and the electric-traffic coupling system dispatching model constructed by the power system dispatching model to obtain the target road topology information and power generation data under the optimal operation cost, thereby generating a coordinated dispatching scheme. Compared with the isolated dispatching processing of the power grid and the traffic network, the present invention makes full use of the flexibility of the topological structure of the traffic network, and reconstructs the topology by adjusting the road topology information of the traffic system, thereby realizing the redistribution of traffic flow, thereby guiding the charging behavior of electric vehicles, and reducing the power generation cost of the power grid and the travel cost of the traffic network.

[0010] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.
[0011] An embodiment of the present invention provides a method for coordinated scheduling of electric and traffic coupling taking into account traffic network topology, including: Acquire current road topology information and road traffic flow of a traffic system in the electric-traffic coupling system, and construct a traffic system scheduling model according to the current road topology information and the road traffic flow; Acquire power generation information of each generator set in the power system of the power-transport coupling system, and construct a power system dispatching model according to the power generation information; According to the traffic system dispatching model and the power system dispatching model, a dispatching model of the electric-traffic coupling system is constructed with minimization of operating cost as the optimization goal; The optimal operating cost obtained based on the solution of the electric-traffic coupling system scheduling model is used to calculate the traffic system scheduling model and the electric power system scheduling model respectively to obtain the reconstructed target road topology information and power generation data, and a collaborative scheduling plan is generated according to the target road topology information and the power generation data.
[0012] From the above description, it can be seen that the beneficial effects of the present invention are: constructing a traffic system scheduling model based on the current road topology information and road traffic flow of the traffic system, and constructing a power system scheduling model based on the power generation information of the power system, solving the operation cost through the traffic system scheduling model and the electric-traffic coupling system scheduling model constructed by the power system scheduling model, so as to obtain the target road topology information and power generation data under the optimal operation cost, thereby generating a collaborative scheduling plan. Compared with the isolated scheduling processing of the power grid and the traffic network, the present invention makes full use of the flexibility of the topological structure of the traffic network, reconstructs the topology by adjusting the road topology information of the traffic system, realizes the redistribution of traffic flow, thereby guiding the charging behavior of electric vehicles, and reducing the power generation cost of the power grid and the travel cost of the traffic network.
[0013] Furthermore, constructing a traffic system scheduling model according to the current road topology information and the road traffic flow includes: Constructing a lane topology reconstruction model according to the current road topology information; A traffic system scheduling model is constructed according to the road traffic flow and the lane topology reconstruction model.
[0014] From the above description, we can see that through strategies such as roadblock setting, personnel guidance, and signal light control, the road topology can be adjusted to achieve the expansion and reduction of road traffic flow. Combining the road traffic flow demand of the current traffic system and the lane topology reconstruction model to build a traffic system scheduling model effectively utilizes the flexibility of the road topology.
[0015] Further, the current road topology information includes original road capacity, current road direction and current road quantity; Constructing a lane topology reconstruction model according to the current road topology information includes: Constructing a road reverse model in which the original road capacity is adjusted to the target road capacity based on the current road direction and the current road quantity; The road direction constraint condition and the road quantity constraint condition for adjusting the traffic system from the original road capacity to the target road capacity are determined.
[0016] From the above description, it can be seen that the road reverse model is constructed to increase the road capacity in the driving direction with heavy traffic, so that vehicles can pass faster and reduce the driving time cost of vehicles, thereby guiding electric vehicles to charge at charging stations that are far away but have surplus power load, avoiding road congestion while reducing the burden on the power system.
[0017] Further, constructing a road reverse model for adjusting the original road capacity to the target road capacity based on the current road direction and the current road quantity includes: ; in, Indicates the road a Adjusted target road capacity, Indicates the road a The original road capacity before adjustment, Representation and Road in opposite direction a Adjusted target road capacity, Representation and Road in opposite direction a The original road capacity before adjustment, and Represents two roads in opposite directions a The number of roads that have their directions reversed, A represents the road set; Determining the road direction constraint condition and the road quantity constraint condition for adjusting the traffic system from the original road capacity to the target road capacity includes: ; ; in, and is a binary variable, indicating the road a different directions, Indicates the total number of roads.
[0018] From the above description, it can be seen that by flexibly adjusting the driving direction of the road, the road capacity is increased, so that vehicles can pass faster. In addition, in the process of adjusting the road direction, the road direction constraint and the road quantity constraint are met to avoid affecting normal traffic driving and ensure the normal operation of the transportation system.
[0019] Furthermore, constructing a traffic system scheduling model according to the road traffic flow and the lane topology reconstruction model includes: Determine the travel time cost of the road according to the road traffic flow, and set the objective function of the traffic system scheduling model according to the road traffic flow and the travel time cost: ; ; in, Indicates the road a of traffic volume, Indicates the road a In traffic volume The travel time cost is , A represents the road set, Represents the economic value of time, represents the free flow travel time, Indicates the road a Adjusted target road capacity.
[0020] From the above description, it can be seen that the traffic system scheduling model aims to minimize the total time cost of all vehicles traveling, which can ensure that electric vehicles travel through the current section of road in the shortest time and reduce unnecessary energy consumption, thereby guiding electric vehicles to charge at charging stations that are far away but have surplus power load, thereby reducing the load on the charging stations.
[0021] Furthermore, constructing a traffic system scheduling model according to the road traffic volume and the lane topology reconstruction model also includes: Determine the constraint conditions of the road traffic flow in the transportation system based on the path allocation.
[0022] From the above description, it can be seen that setting constraint conditions for allocating road traffic flow based on paths can guide vehicles to choose paths more reasonably, thereby alleviating traffic congestion, while effectively optimizing the road topology and improving the throughput capacity of traffic flow.
[0023] Furthermore, the power generation information includes the power generation and power generation cost of each generator set; Constructing a power system dispatch model according to the power generation information includes: According to the power generation power of each generator set, a power system dispatching model with minimization of power generation cost as an objective function is constructed; Determine the power upper and lower limit constraints, the energy storage power constraints, and the active power balance constraints of the nodes including the electric vehicle charging station in the power system.
[0024] From the above description, it can be seen that setting upper and lower power limit constraints can ensure the safe operation of the power grid, setting energy storage power constraints can ensure the charging and discharging balance of energy storage nodes, and electric vehicle charging stations are coupling nodes between the power system and the transportation system. Setting active power balance constraints for nodes containing electric vehicle charging stations can fully consider the coupling interaction between the power system and the transportation system, that is, considering the impact of electric vehicle charging demand on the power system, ensuring the stable operation of the power system, and the three constraints can effectively ensure the reliability of the power system operation.
[0025] Furthermore, constructing an electric-traffic coupling system scheduling model according to the traffic system scheduling model and the power system scheduling model includes: The coupling objective function of the electric-traffic coupling system scheduling model is set based on the objective function of the traffic system scheduling model, the objective function of the electric power system scheduling model and the lane topology reconstruction cost: ; represents the coupling objective function, Represents the objective function of the traffic system scheduling model , represents the objective function of the power system dispatch model, represents the lane topology reconstruction cost; in, Indicates i The generating capacity of the generator set is The cost of electricity generation at Indicates i Generator sets in t The power generation of the time period, S represents the set of generator sets, represents the traffic volume on road a, Indicates the road a In traffic volume The travel time cost is , A represents the road set, and is a binary variable, indicating the road a different directions, Indicates the unit cost of changing lane direction.
[0026] From the above description, it can be seen that the scheduling model of the electric-traffic coupling system aims to minimize the sum of the vehicle's travel time cost, the power generation cost of the power grid and the road topology reconstruction cost. It can take into account the vehicle's travel time cost and the traffic topology reconstruction cost while minimizing the power generation cost, thereby realizing the coordinated optimization of the electric and traffic systems.
[0027] Furthermore, based on the optimal operating cost obtained by solving the electric-traffic coupling system scheduling model, the traffic system scheduling model and the power system scheduling model are calculated respectively, and the reconstructed target road topology information and power generation data are obtained, including: Based on the optimal operating cost, the traffic system dispatching model and the power system dispatching model are respectively calculated to obtain target road traffic flow and power generation data; Substitute the target road traffic flow into the lane topology reconstruction model to solve and calculate to obtain the target road topology information.
[0028] From the above description, it can be seen that the power generation data corresponding to the power system and the target road traffic flow corresponding to the traffic system are used to determine the optimal operating cost, so that the final lane topology structure is determined based on the target road traffic flow corresponding to the traffic system. Based on the final lane topology structure, the topology of the traffic network is reconstructed to increase the road capacity to the required target road traffic flow, thereby improving the comprehensive benefits of the power-traffic coupling system.
[0029] Another embodiment of the present invention provides an electric-transportation coupling collaborative scheduling terminal taking into account the topology of the transportation network, comprising a memory, a processor, and a computer program stored on the memory and running on the processor, wherein the processor implements each step of the above-mentioned electric-transportation coupling collaborative scheduling method taking into account the topology of the transportation network when executing the computer program.
[0030] From the above description, it can be seen that the beneficial effects of the present invention are: constructing a traffic system scheduling model based on the current road topology information and road traffic flow of the traffic system, and constructing a power system scheduling model based on the power generation information of the power system, solving the operation cost through the traffic system scheduling model and the electric-traffic coupling system scheduling model constructed by the power system scheduling model, so as to obtain the target road topology information and power generation data under the optimal operation cost, thereby generating a collaborative scheduling plan.
