Abstract

The transition of passive distribution network towards being active network results in many operation challenges. Voltage control is one of these challenges. This paper has studied the effectiveness of four voltage controlling techniques in a real 132/33/11kV distribution network from Oman which are on-load tap changer control, energy storages installation, transformer tap staggering and power curtailment control. The network has been stressed by large penetration of solar photovoltaic and wind farm power plants. Each techniques have performed differently in maintaining the voltages profile within the statutory limits ±6%. The lowest effectiveness level is the power curtailment, and that is due to the high X/R ratio, as the studied network constitute of overhead lines more than cable lines. Regarding losses reduction effects, energy storage was the highest efficient method whereas the transformer tap staggering control was the lowest efficient method. Moreover, Quasi Dynamic simulation method was used for variable load modeling which has increased the opportunity of large DGs accommodation compared to the static load simulation.
