Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of power grid control, and particularly to an electric-traffic coupled collaborative scheduling method and terminal considering the topology of the traffic network. Background Art
[0002] The global fossil energy crisis has drawn increasing attention. The widespread use of electric vehicles is still accelerating, and the rapid growth of the electric vehicle ownership rate has made the connection between the power grid and the urban traffic network closer. Therefore, the collaborative scheduling of the power grid and the traffic network to achieve the optimal operation of the coupled system is crucial.
[0003] Currently, the power dispatching of the power grid and the traffic flow dispatching of the traffic network are usually processed separately. In the face of the scenario where a large number of electric vehicles are connected to the power grid for charging, this separated dispatching mode is likely to lead to overloading of power lines and traffic congestion on roads. On the one hand, as an important load of the power system, electric vehicles may uncontrollably choose the same charging stations when charging their batteries during peak hours, resulting in over-limit power feeding of power lines and having an adverse impact on the safe and economic operation of the power system. On the other hand, a large number of electric vehicles may queue near the same charging station at the same time, which not only exacerbates the burden on the power system but also easily causes traffic jams near the charging station. Therefore, electric vehicles play a crucial role in coupling the two systems. By reasonably guiding the charging behavior of electric vehicles, it is expected to significantly reduce the congestion and costs of both the power grid and the traffic network.
[0004] Although there have been relevant studies dedicated to solving the problem of electric-traffic coupled collaborative scheduling and exploring the flexibility of electric vehicles and charging stations in the traffic network, these studies usually ignore the flexibility of the traffic network topology. In existing studies, the traffic network topology is often regarded as a fixed factor. In fact, through strategies such as roadblock setting, personnel guidance, and signal light control, the topology of the traffic network can be reconstructed. Therefore, in the problem of electric-traffic coupled collaborative scheduling, the use of traffic network topology reconstruction to improve the performance of the overall system has not been fully considered. Summary of the Invention

[0019] To describe the technical content, achieved objectives and effects of the present invention in detail, the following is described in conjunction with the implementation manners and accompanied by the drawings.
[0020] An embodiment of the present invention provides an electric-traffic coupled collaborative scheduling method considering the topology of the transportation network, including:
[0021] Obtain the current road topology information and road traffic flow of the transportation system in the electric-traffic coupled system, and construct a transportation system scheduling model according to the current road topology information and the road traffic flow;
[0022] Obtain the power generation information of each generator set in the power system of the electric-traffic coupled system, and construct a power system scheduling model according to the power generation information;
[0023] Construct an electric-traffic coupled system scheduling model with the minimum operation cost as the optimization objective according to the transportation system scheduling model and the power system scheduling model;
[0024] Based on the optimal operation cost obtained by solving the electric-traffic coupled system scheduling model, calculate the transportation system scheduling model and the power system scheduling model respectively to obtain the reconstructed target road topology information and power generation data, and generate a collaborative scheduling plan according to the target road topology information and the power generation data.
[0025] As can be seen from the above description, the beneficial effects of the present invention are as follows: A transportation system scheduling model is constructed based on the current road topology information and road traffic flow of the transportation system, and at the same time, a power system scheduling model is constructed based on the power generation information of the power system. The electric-traffic coupled system scheduling model constructed by the transportation system scheduling model and the power system scheduling model is used to solve the operation cost, so as to obtain the target road topology information and power generation data under the optimal operation cost, and then generate a collaborative scheduling plan. Compared with the isolated scheduling of the power grid and the transportation network, the present invention makes full use of the flexibility of the topology structure of the transportation network, realizes the redistribution of traffic flow by adjusting the road topology information of the transportation system for topology reconstruction, thereby guiding the charging behavior of electric vehicles, and at the same time reducing the power generation cost of the power grid and the travel cost of the transportation network.
[0026] Further, constructing a transportation system scheduling model according to the current road topology information and the road traffic flow includes:
[0027] Construct a lane topology reconstruction model according to the current road topology information;
[0028] Construct a traffic system scheduling model based on the road traffic flow and the lane topology reconstruction model.
[0029] As can be seen from the above description, through strategies such as roadblock setting, personnel guidance, and signal light control, the topological structure of the road can be adjusted, thereby realizing the expansion and reduction of the road traffic flow. Combining the road traffic flow demand of the current traffic system and the lane topology reconstruction model to construct a traffic system scheduling model effectively utilizes the flexibility of the road topological structure.
[0030] Furthermore, the current road topological information includes the original road capacity, the current road direction, and the current road number;
[0031] Constructing a lane topology reconstruction model based on the current road topological information includes:
[0032] Construct a road reverse model that adjusts the original road capacity to the target road capacity based on the current road direction and the current road number;
[0033] Determine the road direction constraint conditions and road number constraint conditions for the traffic system to adjust from the original road capacity to the target road capacity.
[0034] As can be seen from the above description, constructing a road reverse model increases the road capacity in the driving direction with more traffic flow, enabling vehicles to pass more quickly, reducing the driving time cost of vehicles, thereby guiding electric vehicles to charging stations that are farther away but have a surplus power load for charging. While avoiding road congestion, the burden on the power system is reduced.
[0035] Furthermore, constructing a road reverse model that adjusts the original road capacity to the target road capacity based on the current road direction and the current road number includes:
[0036] ;
[0037] Among them, represents the target road capacity after the adjustment of road a , represents the original road capacity before the adjustment of road a , represents the target road capacity after the adjustment of the road in the opposite direction to a , represents the original road capacity before the adjustment of the road in the opposite direction to a , and respectively represent the number of roads a undergoing direction reversal in two opposite directions, and A represents the set of roads;
[0038] The road direction constraint conditions and road quantity constraint conditions for determining that the traffic system is adjusted from the original road capacity to the target road capacity include:
[0039] ;
[0040] ;
[0041] Among them, and are binary variables representing different directions of road a , represents the total number of roads.
[0042] As can be seen from the above description, by flexibly adjusting the driving direction of the road, the road capacity is increased, enabling vehicles to pass more quickly. In addition, during the process of adjusting the road direction, the road direction constraints and road quantity constraints are satisfied to avoid affecting normal traffic and ensure the normal operation of the traffic system.
[0043] Furthermore, constructing a traffic system scheduling model according to the road traffic flow and the lane topology reconstruction model includes:
[0044] Determining the driving time cost of the road according to the road traffic flow, and setting the objective function of the traffic system scheduling model according to the road traffic flow and the driving time cost:
[0045] ;
[0046] ;
[0047] Among them, represents the traffic flow of road a , represents the driving time cost of road a when the traffic flow is , A represents the set of roads, represents the economic value of time, represents the driving time of free flow, represents the adjusted target road capacity of road a .
[0048] As can be seen from the above description, the traffic system scheduling model aims to minimize the total time cost of all vehicle driving, which can ensure that electric vehicles drive through the current section in the shortest time, reduce unnecessary power consumption, and thus guide electric vehicles to charging stations with a longer distance but a surplus of power load to reduce the load of the charging stations.
[0049] Further, constructing a traffic system scheduling model based on the road traffic flow and the lane topology reconstruction model further includes:
[0050] Determine the constraint conditions of the road traffic flow based on path allocation in the traffic system.
[0051] As can be seen from the above description, setting the constraint conditions of the road traffic flow based on path allocation can guide vehicles to choose paths more reasonably, thereby alleviating traffic congestion. At the same time, it can effectively optimize the road topology structure and improve the throughput capacity of traffic flow.
[0052] Further, the power generation information includes the power generation power and power generation cost of each generator set;
[0053] Constructing a power system scheduling model based on the power generation information includes:
[0054] Construct a power system scheduling model with the minimum power generation cost as the objective function based on the power generation power of each generator set;
[0055] Determine the constraint conditions of the upper and lower power limits in the power system, the constraint conditions of the energy storage power, and the constraint conditions of the active power balance of the nodes including electric vehicle charging stations.
[0056] As can be seen from the above description, setting the upper and lower power limit constraint conditions can ensure the safe operation of the power grid. Setting the energy storage power constraint conditions can ensure the charge and discharge balance of the energy storage nodes. As the coupling node of the power system and the traffic system, setting the active power balance constraint conditions of the nodes including electric vehicle charging stations can fully consider the coupling interaction between the power system and the traffic system, that is, consider the impact of the charging demand of electric vehicles on the power system, and ensure the stable operation of the power system. Through the three constraint conditions, the reliability of the power system operation can be effectively guaranteed.
[0057] Further, constructing an electric-traffic coupling system scheduling model based on the traffic system scheduling model and the power system scheduling model includes:
[0058] Set the coupling objective function of the electric-traffic coupling system scheduling model based on the objective function of the traffic system scheduling model, the objective function of the power system scheduling model, and the lane topology reconstruction cost:
[0059] ;
[0060] represents the coupling objective function, represents the objective function of the traffic system scheduling model , represents the objective function of the power system scheduling model, represents the lane topology reconstruction cost;
[0061] Among them, represents the i th generator set's power generation cost when the power generation power is . represents the i th generator set's t time period's power generation power. S represents the set of generator sets, represents the traffic flow of road a, represents road a 's travel time cost when the traffic flow is . A represents the set of roads, and are binary variables, representing different directions of road a . represents the unit cost of changing the lane direction.
[0062] As can be seen from the above description, the electric-traffic coupling system scheduling model aims to minimize the sum of the vehicle travel time cost, the power grid power generation cost, and the road topology reconstruction cost. It can consider the vehicle travel time cost and the traffic topology reconstruction cost while minimizing the power generation cost, achieving the collaborative optimization of the electric and traffic systems.
[0063] 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 obtained include:
[0064] Based on the optimal operating cost, the traffic system scheduling model and the power system scheduling model are calculated respectively to obtain the target road traffic flow and power generation data;
[0065] Substitute the target road traffic flow into the lane topology reconstruction model for solution calculation to obtain the target road topology information.
[0066] As can be seen from the above description, the power generation data corresponding to the power system and the target road traffic flow corresponding to the traffic system are determined when determining the optimal operating cost. Thus, based on the target road traffic flow corresponding to the traffic system, the final lane topology structure is determined, and the traffic network topology is reconstructed based on the final lane topology structure to increase the road capacity to the required target road traffic flow, improving the comprehensive benefits of the electric-traffic coupling system.
[0067] Another embodiment of the present invention provides an electric-traffic coupled collaborative scheduling terminal considering the traffic network topology, including a memory, a processor, and a computer program stored on the memory and running on the processor. When the processor executes the computer program, each step in the above-mentioned electric-traffic coupled collaborative scheduling method considering the traffic network topology is implemented.
[0068] As can be seen from the above description, the beneficial effects of the present invention are as follows: Based on the current road topology information and road traffic flow of the traffic system, a traffic system scheduling model is constructed, and at the same time, a power system scheduling model is constructed based on the power generation information of the power system. The electric-traffic coupled system scheduling model constructed by the traffic system scheduling model and the power system scheduling model is used to solve the operating cost, so as to obtain the target road topology information and power generation data under the optimal operating cost, and then generate a collaborative scheduling plan. Compared with the isolated scheduling of the power grid and the traffic network, the present invention makes full use of the flexibility of the traffic network topology structure, realizes the redistribution of traffic flow by adjusting the road topology information of the traffic system for topology reconstruction, thereby guiding the charging behavior of electric vehicles, and at the same time reducing the power generation cost of the power grid and the travel cost of the traffic network.
