摘 要:針對無功優(yōu)化面臨的實際問題,建立了融合有功網(wǎng)損、節(jié)點電壓偏移和無功補償成本的多目標優(yōu)化模型。在傳統(tǒng)粒子群算法(PSO) 的基礎(chǔ)上,動態(tài)調(diào)節(jié)慣性權(quán)重并引入禁忌搜索算法(TS) 的禁忌表,設(shè)置靈活存儲結(jié)構(gòu)和禁忌準則,保證有效搜索多樣化,彌補了全局尋優(yōu)能力不足、易陷入局部最優(yōu)的缺點。IEEE14 節(jié)點系統(tǒng)的仿真結(jié)果表明提出的方法具有較好的全局尋優(yōu)能力和搜索性能。

Abstract: According to the practical issue of reactive power optimization, this paper established a multi-objective optimization model mixed together with the active power transmission losses, the node voltage deviation and the reactive compensation cost. Based on the traditional particle swarm algorithm, the inertia weight was adaptively adjusted according to the fitness and the taboo list of taboo search algorithm was introduced to set up the flexible storage structure and taboo criterion, so as to ensure the searching effectively, which makes up for the deficiency of the global optimization performance and the defect of falling into local optimum. The simulation result of IEEE14 node system shows that the method mentioned above has better global optimization capacity and searching performance.
Key words: reactive power optimization; particle swarm algorithm; taboo list; multi-objective optimization
