摘 要：雞群優(yōu)化算法是模仿雞群覓食的群體智慧發(fā)展而來的生物啟發(fā)式算法，將雞群優(yōu)化算法應(yīng)用到配電網(wǎng)重構(gòu)當(dāng)中，充分利用雞群優(yōu)化算法高效的全局和局部搜索能力，快速尋找使配電網(wǎng)在滿足約束條件下目標(biāo)函數(shù)最小的網(wǎng)絡(luò)狀態(tài)，保證配電網(wǎng)運(yùn)行的經(jīng)濟(jì)性和可靠性。給出了基于雞群優(yōu)化算法的配電網(wǎng)重構(gòu)具體實(shí)現(xiàn)流程，以IEEE33 節(jié)點(diǎn)系統(tǒng)為例，采用雞群優(yōu)化算法(CSO) 和粒子群算法(PSO) 兩種算法進(jìn)行仿真實(shí)驗(yàn)，結(jié)果表明雞群優(yōu)化算法較粒子群算法搜索效率平均提高了11.6%，尋優(yōu)速度更快更穩(wěn)定。

Abstract: The chicken swarm optimization algorithm is a biological heuristic algorithm which imitates chicken swarm foraging of collective intelligence development. The chicken swarm optimization algorithm was applied in distribution network reconfiguration. This algorithm was with the high-efficiency global and local search capability to rapidly look for the network state with minimal objective function meeting the constraint requirements in distribution network, so as to ensure the economical efficiency and reliability of distribution network operation. This paper gave the concrete realization flowchart of distribution network reconfiguration, took the IEEE33 nodes system for example and carried out simulation experiment with the algorithms of chicken swarm optimization and particle swarm optimization. The results show that the search efficiency of chicken swarm optimization algorithm increases by 11.6% on average than the particle swarm algorithm, and optimization speed is faster and more stable.
Key words: chicken swarm optimization algorithm; distribution network reconfiguration; classification optimization; loop coding
