Özet
Nowadays, the increasing penetration of electric vehicle charge stations and photovoltaic generators in the power system can potentially increase the voltage unbalance levels, since a considerable proportion of these devices are single-phase connected, and their total power rating and output are varied. In addition, voltage unbalance is established by the random distribution of single-phase loads throughout the three phases and their uneven distribution. Unbalanced voltage diminishes the power quality of the power distribution system, raises the maintenance costs of distribution operators, and drastically decreases the efficiency of electrical machines. Consequently, reducing voltage unbalance is one of the most important priorities in the power system sector today. In this thesis, the definitions of voltage unbalance of different electrical power communities, its calculation methods, causes, severity, consequences, and the literature works on voltage unbalance mitigation have been examined and evaluated. In addition, a three-phase four-wire power distribution system model with a single feeder has been created using Simulink to examine the levels of voltage unbalance caused by various load and generating units on the system and develop a mitigating solution to introduce voltage unbalance on the feeder. Household loads and electric vehicle chargers with different power ratings and photovoltaic generators connected along the feeder. By varying the power ratings of both the loads and the generating units, several scenarios are simulated, and the voltage unbalance levels in each case are measured. An active voltage unbalance compensator, which is based on a novel control approach, has been developed to mitigate voltage unbalance. The voltage unbalance compensator was placed at the PCC, and it was controlled to mitigate VU. The simulation results have validated the efficacy of the proposed method since voltage unbalance is removed in all examined circumstances.
