Transmission congestion is a serious issue in transmission networks. In the PSAT MATLAB environment, this article suggested an NR (Newton Rapshon) based algorithm for tackling transmission congestion problems.NR based evolutionary technique is used for optimum co-ordination of series controllers with imaginary power sources present in transmission network. In this article author evaluate voltage stability, real power loss reduction, and running cost by using power flow. Transmission loss magnifies the total system running cost. It also manages the improvement of VAR power because its...
