摘　　要：针对分布式电源接入配电网后会对电网电能质量产生不利影响的问题,对分布式电源的接入容量及位置进行了研究。在以配电电能质量符合国家标准的前提下,采用一种结合人工蜂群算法的分布式电源准入功率最大化配置方法对分布式电源准入功率进行了计算。针对多种分布式电源接入配电网的情况,首先分析了不同接入位置和不同容量的分布式电源对电网的影响;然后考虑了分布式电源对配电网电压偏差和谐波的影响;最后利用算例对优化配置方法的可行性进行了测试,确定了分布式电源接入配电网的优化配置方案。研究结果表明,该优化方案能够达到优化目标,满足电压调整和谐波畸变限制的约束条件,最大化地提高分布式电源准入功率,同时为分布式电源最佳接入点提供参考。Aiming at the harmonic problem of the distributed generation （DG） connected with power distribution network,the capacity and installation of DG in power distribution network were studied.The DG penetration levels were calculated by artificial bee colony（ABC） algorithm in compliance with the limitation of harmonics in GB/T14549-1993.The impact of harmonic injectioni on power distribution network caused by capacity and installation of DG was analyzed; The limitations in compliance with the requirements of voltage regulation and harmonic distortion were determined ; The DG penetration level was calculated complying with the limitation of harmonics by ABC algorithm.The results indicate that,the method for calculating DG penetration level can achieve the optimization goal,satisfy the constraint voltage adjustment and harmonic distortion limits,maximize access power distributed power,and provide the reference for the distributed power supply the best integrationpoint.
