Description

Technical Field

[0001] The present application relates to the field of fault handling in power substations, and in particular to a method and system for dispatching power generation vehicles within power substations. Background Art

[0002] Until the fault is corrected or repaired, emergency measures such as generator trucks can provide critical power resources to key facilities or activities in the faulty substation. However, in most substation faults, more than one generator truck is required. In these cases, scheduling and planning for the newly connected generator trucks is necessary to minimize any adverse effects when they are connected to the faulty substation.

[0003] In the existing technology, only the access point scheduling planning for a single generator vehicle is usually considered, and the selection is made based on the optimization algorithm. The access and scheduling of multiple generator vehicles in the substation area is rarely considered, and the newly connected generator vehicle is generally selected, connected and scheduled only based on the power supply demand of the substation area. However, before the new generator vehicle is connected, one or more generator vehicles have been connected to the substation area for emergency power supply, that is, the substation area already has a certain stable load distribution. At this time, if the newly connected generator vehicle is scheduled only considering the power supply demand of the substation area, it will lead to an unbalanced load after the new generator vehicle is connected, causing unnecessary losses and safety hazards. At the same time, the unreasonable location of the newly connected generator vehicle will lead to an unreasonable reduction in the overall utilization rate of the generator vehicles in the substation area and uneven power supply quality in the substation area, which will reduce the power generation quality and the user experience. Therefore, how to reasonably schedule the newly connected generator vehicle in the faulty substation area is still a difficult problem that needs to be solved in the existing technology.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, unless otherwise clearly specified, "multiple" and "several" mean two or more.

[0053] The existing access and scheduling of generator vehicles in faulty substations generally only considers access scheduling planning for a single unit and makes selections based on optimization algorithms. However, the sequential access scheduling of multiple generator vehicles is rarely involved, and the newly connected generator vehicles are usually selected, connected, and scheduled only based on the power supply needs of the substation. However, this access scheduling method will cause a certain degree of load imbalance after the new generator vehicle is connected, resulting in unnecessary losses and safety hazards. At the same time, it will also lead to a decrease in the overall utilization rate of generator vehicles in the substation and uneven power supply quality in the substation, resulting in reduced power generation quality and a decline in user experience. Therefore, how to reasonably schedule the newly connected generator vehicles in the faulty substation is still a difficult problem that needs to be solved urgently in the existing technology.

[0054] Based on the above technical background, please refer to Figure 1 The embodiment of the present application provides a method for dispatching power generation vehicles within a substation, including steps S101 to S104, each of which is specifically as follows:

[0056] In certain embodiments of the present application, the node operation log includes electrical parameters, non-electrical parameters and node operation status of each node; the substation topology is stored in the form of an adjacency matrix.

[0057] In certain embodiments of the present application, obtaining the operating data of the faulty substation specifically includes:

[0058] Obtaining node operation data of the faulty substation and access data of substations connected to the power generation vehicle;

[0059] Constructing a substation topology of the fault substation according to the node location in the node operation data and the substation access location in the substation access data;

[0060] The power supply demand of the fault substation is obtained based on the node operation log in the node operation data and the power time series change data in the substation access data.

[0061] This application first obtains the node operation data of the faulty substation and the substation access data of the connected power generation vehicle, and then obtains the substation topology of the faulty substation based on the node location in the node operation data and the substation access location in the substation access data, and obtains the power supply demand of the faulty substation based on the node operation log in the node operation data and the power time series change data in the substation access data. This can improve the accuracy of the current substation topology and current power supply demand of the obtained faulty substation, and thus improve the accuracy and rationality of selecting the target power generation vehicle based on the substation topology and power supply demand.

[0062] Step S102: performing power flow calculation on the faulty substation according to the substation topology to obtain the node load distribution of the faulty substation.

[0063] In certain embodiments of the present application, the power flow calculation method includes but is not limited to the Gauss-Seidel method, the Newton-Raphson method or the PQ decomposition method, and the preferred embodiment is the Newton-Raphson method.

[0064] In certain embodiments of the present application, performing power flow calculation on the faulty substation based on the substation topology to obtain the node load distribution of the faulty substation specifically includes:

[0065] According to the substation topology, a substation topology model of the fault substation is constructed, and according to the node operation log, parameters of the substation topology model are filled to obtain a substation simulation calculation model;

[0066] According to the node operation log and the power time series change data, the power flow calculation is performed on the substation simulation calculation model to obtain the node load distribution of the fault substation.

[0067] This application first constructs a substation topology model of the fault substation based on the substation topology, and then fills in parameters according to the node operation log, which can obtain a more accurate substation simulation calculation model, which is convenient for subsequent power flow calculation. Then, the power flow calculation is performed by combining the node operation log and the time series change data of the electricity, which can obtain a more reasonable node load distribution and improve the rationality of the subsequent selection of the target power generation vehicle according to the node load distribution.

[0071] determining a vehicle energy replenishment mode of the target power generation vehicle according to the time series change data of the electric quantity, and selecting a target power generation vehicle from the first candidate power generation vehicles according to the vehicle energy replenishment mode;

[0072] An initial access position of the target power generation vehicle is determined according to the substation topology and the node load distribution.

[0073] In certain embodiments of the present application, the vehicle energy replenishment method of the target power generation vehicle is determined based on the time-series change data of the electric quantity, specifically: based on the time-series change data of the electric quantity, the time-series change data of the power supply demand of the fault substation is obtained; based on the time-series change data of the power supply demand, the stage power supply peak is determined; based on the stage power supply peak, the vehicle energy replenishment method of the target power generation vehicle is determined.

[0074] In certain embodiments of the present application, the vehicle energy replenishment method may be a method for replenishing the energy of a target power generation vehicle. Specifically, the energy replenishment method for the target power generation vehicle is related to the type of the target power generation vehicle. More specifically, when the target power generation vehicle is a power generation vehicle, the vehicle energy replenishment method may be to charge the power generation vehicle or to replace the battery on the target power generation vehicle used to power the substation. When the target power generation vehicle is a fuel-powered power generation vehicle, the vehicle energy replenishment method may be to replenish the fuel-powered power generation vehicle with the corresponding fuel.

[0075] In certain embodiments of the present application, the initial access position of the target power generation vehicle is determined based on the substation topology and the node load distribution, specifically: the position of the node with the smallest node load in the node load distribution is used as the initial access position of the target power generation vehicle.

[0076] This application first screens candidate power generation vehicles according to power supply demand, and can exclude candidate power generation vehicles that do not meet the power supply demand, narrow the selection range, and avoid inaccurate selection. Then, the vehicle energy replenishment method is determined according to the time series change data of the power supply, and then the target power generation vehicle is selected. The target power generation vehicle can be selected more accurately according to the vehicle energy replenishment method, so that the selected target power generation vehicle is more suitable for the current substation access task, and the rationality of the selection of the target power generation vehicle is improved.

[0077] Step S104: According to the operating data, based on a dynamic programming algorithm, the initial access position is optimized and solved to obtain the substation access position of the target power generation vehicle, and the target power generation vehicle is dispatched to the substation access position for grid connection.

[0078] In certain embodiments of the present application, optimizing and solving the initial access position based on the operating data and a dynamic programming algorithm to obtain the access position of the target power generation vehicle specifically includes:

[0079] Based on the operating data, the initial access position of the target power generation vehicle is iteratively solved. During the iteration, the power flow calculation is performed based on the optimization algorithm according to the access data of the substation, and the initial access position is adjusted according to the power flow calculation result combined with the dynamic programming algorithm until the fault substation reaches load balance.

[0080] The initial access position of the last iteration is used as the access position of the target power generation vehicle.

[0081] In certain embodiments of the present application, the optimization algorithm includes but is not limited to a simulated annealing algorithm, a particle swarm optimization algorithm, a genetic algorithm or an ant colony optimization algorithm, and improved algorithms of the aforementioned algorithms, and a preferred embodiment is the particle swarm optimization algorithm.

[0082] This application first iteratively solves the initial access position of the target power generation vehicle based on the operating data, combined with the optimization algorithm and the dynamic programming algorithm, and then obtains the substation access position, which can more accurately determine the substation access position of the target power generation vehicle and improve the rationality of the substation access position of the target power generation vehicle, thereby improving the rationality of the subsequent scheduling of the target power generation vehicle to the substation access position for grid connection.

[0083] Compared with the existing technology, the present application first obtains the operating data of the fault substation, and then obtains the node load distribution through flow calculation, and then combines the operating data and node load distribution to select the target power generation vehicle from the candidate power generation vehicles and determine the initial access position, which can make the selected target power generation vehicle more suitable for the current substation access task and improve the rationality of the selection of the target power generation vehicle; then based on the dynamic programming algorithm, the initial access position is optimized and solved, which can improve the rationality of the substation access position of the target power generation vehicle, thereby improving the scheduling rationality when dispatching the target power generation vehicle to the substation access position for grid connection.
