Auxiliary decision-making method for power distribution dispatching based on multi-dimensional

Abstract

The invention relates to a power distribution scheduling aid decision making method based on multiple dimensions. The method is characterized by including the following steps that 1 terminals of an energy management system, a power distribution network management system and a power distribution scheduling aid decision making system are connected through a scheduling communication network; 2 the energy management system acquires the current power distribution network operation state and real-time line data information; 3 the power distribution network management system adopts a self-adaptation immune algorithm to process the power distribution network operation state and the line data and builds a transfer load mathematical model for a power distribution network and for transfer load calculation; 4 a radar map with five dimensions is generated on the terminal of the power distribution scheduling aid decision making system to provide an aid decision making basis for a scheduling worker. The method is reasonable in design, adopts the core algorithm of the power distribution network transfer load, achieves real-time online management of the power distribution network, effectively solves the problem that the existing switching operation relies on the experience of the scheduling worker, is low in efficiency and the like, improves power grid stability and reliability and reduces power failure time for users.

Description

technical field [0001] The invention belongs to the technical field of power distribution networks, in particular to a multi-dimensional auxiliary decision-making method for power distribution dispatching. Background technique [0002] In recent years, with the continuous development of power grid construction, the structure of power grids at all levels has been significantly strengthened. However, the urban distribution network is still relatively weak compared with the main network in terms of grid structure and management level. At present, the central urban areas of the distribution network are mostly cables, and the network structure adopts a ring network structure, while the suburban areas with more loads are mostly overhead lines, and the network structure has radial, single-connection or multi-connection methods. [0003] At present, dispatching manages the distribution network mainly through the management of drawings and materials. The dispatcher modifies the draw...

Problems solved by technology

[0004] In fact, in the distribution network load reversal and accident handling (i.e., load transfer), it is often necessary to consider whether there is a power guarantee task, operational complexity (the number of operating switches is the least), the number of dual power supply users, and whether it will be overloaded (whether the branch current will exceed the limit), whether the loop can be closed (whether the bus voltage will exceed the limit), if not properly grasped, it will not only reduce the reliability of power supply, but will even have a great impact on the stability of the power grid
