Analysis of unbalanced radial distribution system with SSVR
2014 Recent Advances in Engineering and Computational Sciences (RAECS), 2014This paper presents modeling of Static Series Voltage Restorer (SSVR) unbalanced radial distribution system (RDS) load flow. To incorporate this approach, an accurate model for SSVR is derived to use in load flow calculations. SSVR reactive power rating as well as direction of required reactive power injection to compensate voltage of a particular node

Current Compensators for Unbalanced Electric Distribution Systems
2018 IEEE Electronic Power Grid (eGrid), 2018Inherent current imbalances are often present in electric distribution systems due to the increase of single-phase generation in the form of renewables and the existence of single-phase loads. The continued expansion of non-linear load usage is also increasing the levels of harmonics through the power transformers servicing these distribution systems ...

Distributed generation in Unbalanced Mesh Distribution System with different unbalances
2014 6th IEEE Power India International Conference (PIICON), 2014Distributed Generation (DG) is an electric power source connected directly to the distribution network or on the customer site of the meter. The penetration of DG may impact the operation of a distribution network in both beneficial and detrimental ways. Some of the positive impacts of DG are: voltage support, power loss reduction, support of ancillary

Distributed Generator Placement And Sizing in Unbalanced Radial Distribution System
Distributed Generation & Alternative Energy Journal, 2010To minimize power losses, it is important to determine the locationand size of local generators to be placed in unbalanced power distribu-tion systems. Because of some inherent features of unbalanced distribu-tion systems, such as radial structure, large number of nodes, and awide range of X/R ratios, the conventional techniques developed forthe ...

Distributed Optimal Voltage Control for Three Phase Unbalanced Distribution Systems with DERs
2020 IEEE Industry Applications Society Annual Meeting, 2020Traditionally, electric utilities have used local (non-optimal) or centralized (optimal) approaches for voltage control in electric distribution grids. However, with increased penetration of distributed energy resources (DERs), voltage control has become increasingly challenging for distribution grid operators.
