Effect of Voltage Variation from Distributed Generation on Very Long Distribution Line with Multiple Voltage Regulators

This paper presents the effect voltage variation from distributed generator (DG) on long distribution line with multiple voltage regulator. The mini hydro power plant is used as distributed generator. This paper considers the operation of DG and automatic voltage regulator (AVR) effected voltage along distribution on varying load. From this study, the operation of DG and AVR has effected to voltage along the long distribution line depended on load varying and location. Therefore, the size of distributed generation has to be considered when it dispatches to the very long distribution system.
