Distributed Algorithm for Volt - VAr Optimization in Unbalanced Distribution System
2020 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2020Conservation voltage reduction (CVR) is implemented in the distribution system to reduce the voltage along the feeder with the objective to reduce the power consumption. Due to the increased penetration of distributed generators in the distribution system the centralized control is cumbersome.

Distributed volt/var control in unbalanced distribution systems with distributed generation
2014 IEEE Symposium on Computational Intelligence Applications in Smart Grid (CIASG), 2014Future power distribution systems are expected to have large number of scale smart measuring devices and distributed generation (DG) units which would require real-time network management. Integration of single-phase DG and advanced metering infrastructure (AMI) technologies will add further complexity to the power distribution system which is ...

Network reconfiguration for unbalanced distribution systems
TENCON 2017 - 2017 IEEE Region 10 Conference, 2017This paper proposes a network reconfiguration methodology for the three-phase unbalanced distribution system under both the normal operating and post-fault conditions. In normal operating condition, network reconfiguration is performed for real power loss minimization whereas, in the post-fault condition, reconfiguration is performed for faulty line ...

Probabilistic evaluation of harmonic impedances in unbalanced distribution systems
2003 IEEE Bologna Power Tech Conference Proceedings,, 2004This paper presents a technique to obtain the probability density functions of network harmonic impedances in an unbalanced three-phase distribution system. In these systems the impedances can significantly vary as a function of time due to the presence of single and multi-phase capacitors, generators and filters which can be switched on and off and ...

Unbalanced distribution system voltage optimisation
2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2016Conservation voltage reduction (CVR), the theory that reducing distribution feeder voltages will result in a reduction in demand, has recently been reintroduced with the aim of improving overall energy efficiency. Although CVR is a simple and cost-effective scheme, reducing voltages may not always be the most beneficial decision in terms of reducing ...
