Distribtuion System with Distributed Generation Load Flow

Open access to the power grid through privatization and environmental concerns are changing the way power systems are built and operated. Many in the power industry are looking to integrate smaller "green" generators into their distribution systems (DSs), which traditionally contain no sources of power generation. Such "green" technologies include wind, solar and small hydro generation. Traditional analysis tools need to be modified to facilitate distribution systems with embedded generation. This paper reports on a distribution load flow (DLF) for DSs with embedded generation. This DLF makes use of a recursive function and a specialized data structure designed to take advantage of the radial nature of DSs. The resulting DLF is fast, flexible and computationally efficient
