摘　　要：随着小水电集中地区分布式清洁能源开发力度越来越大,电压质量降低成为辐射型配电网所面临的主要问题。针对小水电集中地方的配电网电压质量降低问题,从主动配电网的角度出发,针对辐射型配电网电压对无功功率和有功功率的灵敏度进行了分析,并在此基础上确定储能元件最佳的设置位置,研究了基于分布式电源(distributed generation,DG)自身和有载调压变压器相结合的新型调压策略,最后利用算例验证其调压效果。结果证明,主动配电网综合调压手段可以在不采用专门的无功补偿装置的前提下大幅度提高DG的渗透水平。With the developing of distributed clean energy in small hydropower concentrated areas, the lower voltage quality has become a major problem of the distribution network right now. With regard with the lower voltage problem of small hydropower concentrated areas, this paper from the perspective of the active distribution network, conducts sensitivity analysis for reactive power and active power of the radiation distribution network. On the basis of the sensitivity analysis, the best position to set storage elements is determined and the novel voltage regulation strategy based on the combination of distributed power and on-load tap changer （OLTC） regulator is proposed. Finally, this paper uses numerical examples to verify its effectiveness. The result proves that the integrated regulation means of active distribution network can greatly improve penetration levels of distributed generation without the use of specialized reactive power compensation device.
