Topological properties of medium voltage electricity distribution networks

Topological Properties of Medium Voltage Electricity

With a large penetration of low carbon technologies (LCTs) at medium voltage and low voltage levels, electricity distribution 9 networks are undergoing rapid changes. Much research has been carried out to analyse the impact of employing LCTs in 10 distribution networks based on either real or synthetic network samples. Results of such studies are usually case specific and of 11 limited applicab...

Planning of Distribution Networks for Medium Voltage and Low Voltage

Stochastic Assessment of Voltage Sags in Distribution Networks

This paper compares fault position and Monte Carlo methods as the most common methods in stochastic assessment of voltage sags. To compare their abilities, symmetrical and unsymmetrical faults with different probability distribution of fault positions along the lines are applied in a test system. The voltage sag magnitude in different nodes of test system is calculated. The problem with the...

The Effectiveness of Dynamic Voltage Restorer with the Distribution Networks for Voltage Sag Compensation

This paper discusses the Dynamic voltage restorer (DVR) operation and control for Voltage sags compensation. DVR is a series connected power electronic based device that can quickly mitigate the voltage sags in the system and restore the load voltage to the pre-fault value. Voltage sag associated with faults in transmission and distribution systems, energizing of transformers, and starting of l...
