Development of a steady state voltage regulation method for power distribution networks

Abstract

Distributed generation (DG) can be known as the power generating technologies that are installed at or close to the power consumption locations and it consists of a significant number of advantages for the power system in which it would reduce the transmission loss to a greater extent. On the contrary, it will be the cause of fluctuating the voltage on the distribution line. Many countries are inclined to observe the over voltage and under voltage fluctuations due to the high integration of inductive loads and distributed generation such as solar and wind power systems. Consequently, the active distribution system is supposed to be properly managed and coordinated. This study is mainly focusing on minimizing the voltage variation of a standard IEEE 33 bus bar system with the efficient placing of custom power devices on it. Moreover, voltage variation when distribution generations and inductive loads are presented on the bus bar system is studied. According to the results, it has been seen that the voltage variation in the existing distribution network can be minimized by placing a static var compensator at optimal locations.
