Abstract:

 

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.
