摘 要:粒子群算法和遺傳算法是現(xiàn)在光伏規(guī)劃中常用的方法,但前者容易陷入局部最優(yōu)點,而后者的迭代收斂速度較慢且計算過程繁瑣。提出了一種新的混合優(yōu)化算法,即將遺傳算法與粒子群算法結(jié)合起來,用二進制編碼的方式將光伏的接入位置加入到粒子的信息中,利用仿真實驗對考慮電能質(zhì)量的光伏優(yōu)化配置進行了驗證分析,并利用改進的混合優(yōu)化算法對數(shù)學(xué)模型進行求解,仿真結(jié)果證明了改進規(guī)劃算法的合理有效性。

Abstract: Particle swarm optimization (PSO) and genetic algorithm (GA) are commonly used in photovoltaic programming nowadays, but the former is easy to fall into local optimum, while the latter has a slow convergence rate and a cumbersome calculation process. This paper proposed a kind of new hybrid optimization algorithm, which combined GA with PSO and used the binary coding mode to make the interconnected location of photovoltaic join the message of particle. The simulation experiment was used to carry out the check analysis to the optimal configuration of photovoltaic system considering power quality and the improved hybrid optimization algorithm was used to solve the problem of mathematic model. The simulation experiments show that the improved planning algorithm is reasonable and effective.
Key words: photovoltaic planning; power quality; distribution network planning; planning algorithm
