Voltage Regulation in Low Voltage Distribution Networks with Embedded Photovoltaic Microgeneration

Voltage Regulation in Low Voltage Distribution Networks with Embedded Photovoltaic Microgeneration

Low voltage distribution networks have been originally designed to feed loads. However, recently, small dispersed renewable generators, mainly photovoltaics, are being connected to the low voltage grids. This new operational framework represents a challenge to the planning and operation of distribution networks, since the multidimensional stochastic dependence structure of the joint behaviour o...

Distributed Voltage Control in Distribution Networks with High Penetration of Photovoltaic Systems

In this paper, a distributed method for reactive power management in a distribution system has been presented. The proposed method focuses on the voltage rise where the distribution systems are equipped with a considerable number of photovoltaic units. This paper proposes the alternating direction method of multipliers (ADMMs) approach for solving the optimal voltage control problem in a distri...

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...
