Abstract
Power distribution networks are swiftly transforming into active distribution networks (ADNs) due to increasing penetration of renewables and electric vehicles. This raises concerns among distribution system operators regarding the power quality issues. Frequent over/under voltages in ADNs are some of the major issues. The advanced devices and control techniques are to be used to prevent system voltage violations to enable efficient and reliable operation. To enhance the insight and comprehension, a precise description regarding the state-of-the-art devices used for voltage control in ADNs, their models and characteristics are provided in this chapter. Various advanced control strategies used for voltage control under different operation scenarios to highly uncertain future power networks are systematically presented, along with their merits and limitations. Finally, a voltage control approach based on dual-stage model predictive control framework is presented and tested on modified 33-bus distribution network to study the voltage control capabilities of PVs and EV charging stations.
