Optimal placement and optimal mix of RDGs for improving voltage stability and maximum loadability using PSAT

This study focuses on finding the optimal location of Renewable Distributed Generators (RDGs) using Continuation Power Flow (CPF) analysis and the sensitivity factor. Also, the optimal mix of different types of RDG units (wind turbines, fuel cells, and solar photovoltaics) is selected. The CPF method is used to study the impact of the integrated RDGs on the voltage stability and maximum load. The proposed method is applied on a IEEE 14-bus system, using Power System Analysis Toolbox (PSAT), which is a MATLAB environment. The results showed that the optimal location and optimal mix of different types of RDGs enhanced the voltage stability and increased the maximum loadability point.
