Voltage control plays an important role in the operation of electricity distribution networks, especially with high penetration of distributed energy resources. These resources introduces significant and fast varying uncertainties. In this paper, we focus on reactive power compensation to control voltage in the presence of uncertainties. We adopt a probabilistic approach that accounts for arbit...

INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY Analysis on Topology of DVR Used in Low-voltage Distribution Grid Yanlei Zhao, Chuanxiao Wang , Jingjing Yan School of Electrical and Electronic Engineering, Shandong University of Technology, Zibo, 255049, China [email protected] Abstract Dynamic voltage restorer (DVR) is a series-connected transient voltage compensation eq...

We investigate correlations of current at contacts and voltage fluctuations at voltage probes coupled to interferometers. The results are compared with correlations of current and occupation number fluctuations at dephasing probes. We use a quantum Langevin approach for the average quantities and their fluctuations. For higher order correlations we develop a stochastic path integral approach an...

Distributed generation (DG) sources are becoming more prominent in distribution systems due to the incremental demands for electrical energy. Locations and capacities of DG sources have great impacts on the system losses in a distribution network. This paper presents a study aimed for optimally determining the size and location of distributed generation units in distribution systems with differ...

The installation of Distributed Generation (DG) can have a significant impact on distribution system voltage regulation. The effects vary according to the DG device: in particular, synchronous generators present voltage control systems which interfere with the voltage regulation of the distribution systems. The paper analyzes two voltage control schemes for synchronous generators connected to M...
