Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the traditional method of post-disaster emergency repair of the current distribution network is to consider the vehicle path or switch sequence alone, without considering the coordinated action of the construction team and the material vehicle, and often cannot achieve the goal of minimum economic loss. Method and device for emergency repair decision-making after network disaster

Embodiment

[0293] The present invention adopts the PG&E 69 node system to verify the effectiveness of the method. Its topology is image 3 shown. The red X indicates the fault line, which are F1(30-31), F2(33-34), F3(65-66), F4(88-89), F5(15-16), F6(20-21) , F7(24-25), F8(35-36), F9(55-56), F10(49-50), the blue dotted line represents the contact line, respectively Y1(10-70), Y2(12-20 ), Y3 (14-90), Y4 (26-54), Y5 (38-48). There are two warehouses, D1 and D2 (not shown in the figure), and nodes 1 to 90 are load points.

[0294] There are four construction teams, A, B, C, and D. There are six material transport vehicles, V1, V2, V3, V4, V5, and V6. The vehicles have the same material carrying capacity, which is 50.

[0295] Assuming that faults occur at the same time, the isolation switch at the fault point is immediately opened to isolate the fault.

[0296] The repair time required for each fault point is shown in Table 1:

Abstract

The invention discloses a post-disaster emergency repair decision-making method and device for a distribution network, which collects fault information distribution level disaster damage information, emergency repair teams, and material transport vehicle information under disaster conditions. The distribution network fault point selection, emergency repair team, and material scheduling are used as decision variables, and an auxiliary decision-making model for distribution network structure reconfiguration and material and personnel deployment is established. The determination model of the construction team and material dispatching scheme with the goal of minimizing the total power loss in the repair process; the upper and lower iterative solution method is used to solve the deployment auxiliary decision-making model, and finally the decision-making plan for the post-disaster repair of the distribution network is determined. The invention fully considers the problem that the coordinated action of the construction team and the material vehicle often cannot achieve the goal of minimum economic loss, and simplifies the coding of each part decomposition.

Description

technical field [0001] The invention belongs to the field of emergency repair and scheduling of electric power systems, and relates to a post-disaster emergency repair decision-making method and device for a distribution network. Background technique [0002] Due to the low design standards of the distribution network, in the process of natural disasters (such as snowstorms, typhoons, etc.), a large number of physical failures of the distribution network will be caused. In the extreme ice and snow disaster in 2008, the power grids of 16 provinces (autonomous regions and municipalities directly under the Central Government) suffered serious damage, such as ice covering of lines, collapse of iron towers, tripping of substations, and large-scale power outages. nearly one billion yuan. After the disaster, the construction team needs to arrange the emergency repair sequence of the construction team according to the post-disaster failure situation. Reasonable and efficient fault...
