Problems solved by technology

However, in practice, due to the large scale of the power distribution system and the high dimensionality of the switch combination variable space, the problem of power supply restoration after a fault is faced with the danger of exhaustive search
In addition, the recovery strategy should comprehensively consider factors such as the number of switching operations, feeder load margin, load recovery amount, network constraints, user priority, etc., but some factors are contradictory, which makes it very difficult to solve the problem

Abstract

The invention relates to a load transfer system used in the case of failure of a 35kV power distribution network on the basis of MAS (Multi-Agents), which is characterized by comprising at least one 35kV power-supply-point power supply region, wherein each 35kV power-supply-point power supply region is formed by a center coordination Agent, a 35kV substation Agent and at least one 10kV power distribution station Agent. A working method of the load transfer system comprises the steps of information collection, processing, recording and storage, judgment and control. The load transfer system has the advantages that 1, load transfer and power recovery are implemented; 2, the problem of exhaustion danger in a search recovery scheme is solved; 3, a failure recovery candidate scheme set is rapidly and accurately obtained; and 4, the load transfer system has high autonomy, subjectivity and reactivity.

Description

(1) Technical field: [0001] The present invention relates to a power supply recovery system and method for urban medium and low-voltage distribution networks, especially a MAS (Multi-Agents—multi-agent)-based load transfer system and method for a 35kV distribution network failure, which belongs to distribution network operation management and fault emergency handling areas. (2) Background technology: [0002] Most of the distribution network is a ring structure, open-loop operation and radial, and its power flow is generally unidirectional along the radial network. Most of my country's distribution network adopts the voltage sequence of 500 / 220 / 110 / 35 / 10kV. Only the Northeast Power Grid adopts the voltage sequence of 500 / 220 / 66 / 10kV, and the Northwest Power Grid adopts the voltage level sequence of 750 / 330 / 66 / 10kV. The loads in the medium and low voltage distribution network area are generally dominated by government agencies, businesses, and residents. They not only have a ...
