“Impact of Distributed Generation on Voltage Stability and Losses in Radial Distribution Networks”

Abstract

The increasing need for enhanced power quality drives modern industry. In the last ten years, there has been a significant rise in consumer awareness regarding dependable power sources. As a result, the growth of small distributed generation (DG) has accelerated. These small, independent DG units can effectively meet local energy demands, improving power reliability at a low initial cost. Such systems are becoming increasingly essential in remote areas where the installation of overhead lines or cables is either too costly or impractical due to various factors. Small generation systems can be efficiently deployed in mountainous regions, rural areas, islands, marine facilities, aircraft, and other locations, including in developing countries. However, it is important to note that these DG units may need to be de-rated if induction motor loads are engaged immediately. A useful strategy to optimize the overall production capacity of the system is to integrate a DSTATCOM in a shunt configuration with the main system. The voltage source converter (VSC) generates the necessary inductive and capacitive reactive power for the DSTATCOM internally. Its rapid response capability can provide suitable reactive power compensation to the connected system.
