Determining the optimum medium voltage level by analysis of different voltage levels

Improving Voltage Stability Margin Using Voltage Profile and Sensitivity Analysis by Neural Network

This paper presents a new approach for estimating and improving voltage stability margin from phase and magnitude profile of bus voltages using sensitivity analysis of Voltage Stability Assessment Neural Network (VSANN). Bus voltage profile contains useful information about system stability margin including the effect of load-generation, line outage and reactive power compensation so, it is ad...

Planning of Distribution Networks for Medium Voltage and Low Voltage

Reactive Power Pricing in an Open Access Environment Considering Combined Optimum Voltage Profile and Voltage Stability

In a de-regulated open access environment, reactive power is one of the ancillary services which must be provided by an Independent System Operator (ISO). In this paper, a new algorithm is proposed in which reactive power resources are initially so tuned that optimum security in terms of voltage profile and voltage stability are achieved while at the same time, the system losses are minimized. ...

Coreless Transformer for Power Quality Measurement at Medium Voltage Level

Original scientific paper Measurement of grid voltage harmonic components is an important part of power quality measurements. Current high voltage transformers with iron core are not linear and cannot easily be used for accurate measurement of "polluted" voltages in wide frequency range. In this paper, design details of a new coreless voltage transformer for power quality measurement are given....
