    摘 要:針對傳統(tǒng)方法在風光儲能系統(tǒng)容量優(yōu)化配置過程中求解精度較低、效率較慢等問題,提出一種改進蜻蜓算法(IDA)。通過采用 Logistic 混沌初始化和非線性慣性權重兩種策略對原始蜻蜓算法進行改進,使算法能夠在初始化階段分布更均勻,全局搜索和局部開發(fā)更加協(xié)調,同時更快鎖定最優(yōu)解區(qū)域;構建混合儲能系統(tǒng)容量優(yōu)化模型,以儲能裝置的生命周期費用作為目標函數(shù),并考慮負荷缺電率、儲能系統(tǒng)能量等約束條件。使用 MATLAB 軟件對算例進行仿真分析,通過 3 種算法的仿真結果對比發(fā)現(xiàn),采用改進蜻蜓算法蓄電池個數(shù)有所減少,全生命周期費用也相對降低,有較好的經濟適用性。

    Abstract: Aiming at the problems of lower solution accuracy and slower efficiency of traditional methods in the process of capacity optimization and configuration of wind energy storage system, an improved dragonfly algorithm (IDA) is proposed. The original dragonfly algorithm is improved by adopting two strategies: Logistic chaotic initialization and nonlinear inertia weights, so that the algorithm can be more uniformly distributed in the initialization stage, the global search and local development can be more coordinated and lock the optimal solution region more quickly at the sametime, constructing the capacity optimization model of the hybrid energy storage system, taking the life-cycle cost of the storage device as the objective function and considering load power shortage rate, energy storage system and other constraints. Finally, this paper uses MATLAB software to simulate and analyze the algorithm, the simulation results of the three algorithms are compared and found, using the improved dragonfly algorithm, the number of storage batteries is reduced, the cost of full life-cycle is also relatively reduced and it has better economic applicability.
    Key words: hybrid energy storage; capacity configuration; improved dragonfly algorithm; chaotic initialization; storage battery; full life-cycle cost
