Agent map-based brittleness self-organization criticality analysis method of marine electric power system

Abstract

The invention discloses an agent map-based brittleness self-organization criticality analysis method of a marine electric power system, comprising the following steps of: firstly, determining an initial state, an initial entropy value and a critical entropy value of each node by utilizing an adaptive Agent map; updating and storing the state and the entropy values of each node according to a node knowledge base of information related to a storage vertex and an IF/THEN principle; then updating a weight of the Agent map according to a weight-solving method; calculating a brittleness evaluation function of the system; increasing the charge of each load node and the capacity of each engine node of the marine electric power system; increasing the maximum transmission capacity of an open-circuit line; and finally extracting a brittleness self-organization criticality characteristic value of the system. According to the invention, an evolution rule of each adaptive main body is specified, the brittleness evaluation function of the whole system is defined, a brittleness model of the marine electric power system is established, each main body in the system and the operation state of the whole system are calculated through the modeling method to obtain a result, the brittleness degree of the system is correctly reflected, and the brittleness prevention capability of the marine electric power system is improved.

Description

technical field [0001] The invention specifically relates to a modeling method for brittle analysis of a ship power system, which belongs to the technical field of ship power systems. Background technique [0002] Fragility is an important attribute of a complex system. For an open complex system, when one of its subsystems is hit by external forces or is disturbed by internal and external forces, the original ordered state is destroyed, the subsystem collapses, and the adjacent material The subsystems that exchange with energy are also destroyed, and the degree of disorder deepens, resulting in collapse, which is recursive in turn. With the increase in the number of collapsed subsystems and the expansion of levels, it will eventually lead to the collapse of the entire complex system. The complex system has this One property is called the brittleness of complex systems. The scale of the modern ship power system is increasing, and the network structure is becoming more and m...
