Abstract
- Voltage profiles of feeders with the connection of distributed generations (DGs) were investigated. A unified typical load distribution model was established. Based on this model, exact expressions of feeder voltage profile with single and double DGs were derived and used to analyze the impact of DGs’s location and capacity on the voltage profile quantitatively. Then, a general formula of the voltage profile was derived. The limitation of single DG and necessity of multiple DGs for voltage regulation were also discussed. Through the simulation, voltage profiles of feeders with single and double DGs were compared. The voltage excursion rate is 7.40% for only one DG, while 2.48% and 2.36% for double DGs. It is shown that the feeder voltage can be retained in a more appropriate range with multiple DGs than with only one DG. Distributing the total capacity of DGs is better than concentrating it at one point. [ABSTRACT FROM AUTHOR]
